Bill Porter November 2nd, 2005, 08:01 PM I don't think the profit is that great and I don't think $1,000 is too expensive. Their "ground glass" (well, whatever it is), as I recall, costs around $500. I don't think it's just some microwax sandwiched between two pieces of glass.
Also you haven't factored in their research costs, development costs, or patent and patent attorney costs - and ignoring paying themselves for their work. Let's say for example they have spent a paltry $25,000 to date, the units cost them around $750 just for the hardware (not counting assembly labor or paying anyone to handle all the sales and aftersale phone/web work), and they sell 500 adapters over the course of two years at $1000 per.
That means once they earn back their $25,000 outlay, Jon and Douglas each make a whopping $25,000 a year at a job where you work 12 hours a day, plus weekends keeping up on the forums and emails, and don't have any job security, benefits, or package. But to top it off, they have to make decently-sized production runs of the machined parts, and do quantity buys of the optics and ground glass, to get acceptable pricing. Let's say they make 25 units at a time. That's another $18,750 they have to front.
That's if everything goes as planned. If a supplier is out of something, or the supplier's equipment breaks, etc, and there are delays, these boys don't get paid, period. Can't sell that you don't have.
So, no, thanks. I prefer a higher paying job with all the fringes and I get to go home after a day's work and not be responsible for everything.
P.S. I can now make an okay static adapter for a pretty low price. But is my uncompressed footage as good as G35 footage? Nope. And I spent a lot of money trying different bits and pieces on the way to this point - and a lot of time. My time is worth something. Sometimes I don't want to get involved, I just want to pay someone who has already spent their own time becoming an expert. This is why many people use mechanics for their cars for doctors for their ailments - they attended school and we pay them for that, rather than us trying to learn it ourselves.
I know for a fact that a lot of people in video production do NOT want to visit dvinfo (as great as it is for those of us here) or screw around learning how to make an adapter and get it tuned just right. They will peel off a thousand or thirteen hundred bucks and not think twice about it. Companies like P+S and Guerilla35 and Movietube are not marketing to most people who even read the forums. They are going to sell to the people who want to buy their product, not the people who are going to try to steal their engineering by reading the patent and trying to DIY.
Oscar Spierenburg November 3rd, 2005, 06:52 AM OK OK Bill, maybe it was €12.-
Like I said, <if you are just making one or two adapters, you can find real quality parts for free or really cheap.>
If I (or Jim or Frank) would want to make a product out of this thing, it will cost allot more to find the same parts. Of course we all know why these pro adapters and things are so expensive, that's why we have this forum. It's accent has changed the last year because more and more people are producing these things and sell them here, which is fine too, but something tells me if it's growing too big, if patents are violated too easily, it will become lots of trouble. What do you think Bill?
Rafael Lopes November 3rd, 2005, 07:53 AM I think it's great that there's so many people "breaking patents" and doing their own stuff. And I really hope that somebody can come out with cheaper and cheaper ways to overcome all the technical flaws of conventional DV. Not everybody can afford 1000$ adapters and 6000$ cameras. I know some extremely creative people who would be able to do wonders if they just had the chance to use the right equipment. As for my self, I know that I had to work hard to buy all my stuff. Of course I would rather have an AG-HV200 than a Gl2! Of course I would rather have a G35 than a Letus35! But hey, tough luck. That's life and I'm very very glad that AT LEAST we have these cheaper alternatives. If I had the money I'd be using the best there is (even though this is kind of relative) but right now I'm very thankful to all of those who were willing to "break the patents" and make the "poor mens' " life a bit easier. THANK YOU! ;)

I think someone needs to chime in here. There is a HUGE misconception in the DIY crowd in regards to patents. In many cases this Alternative-imaging forum goes over the line (as grey as it may be). Patents are put into place to protect inventors and their ideas. Patents are good. Regardless of how much an inventor charges for their device, they have a right to protect it. When developers step over the line by not researching current patents and their claims, and release a product in order to make a quick buck, that is when things turn ugly for everyone. The "Poor mens" don't benefit when larger companies start throwing lawsuits around.
Cheers,
Jonathan-
Bill Porter November 3rd, 2005, 12:56 PM Not to sound like a G35 cheerleader but I have wholeheartedly agreed for a long time. Without patents to protect the inventors, few would invent because their money and work would then be ripped off by companies with the money to hamstring them. This is why medical patents are so much more protective than other patents - we may WANT product innovation so we can have our G35's and motorized seat belts and all other patented devices, but we NEED medical innovation. The best way to create that is to reward the inventors by protecting them.
I used to own a manufacturing business (including in-house R&D) in a completely different industry than cameras/video/etc. For years we were the leaders and pushed the field forward technologically by giant steps with our products. Then the big companies started cloning my stuff. Some even had the audacity (read: lack of morals) to claim they invented it! I tired of this and stopped developing. As a result, the industry screeched to a halt and there was literally no change in the product lines on the market for about five years(!). People would call and beg to get "just one" of the unreleased products which we had stopped development on. But why should I? I was sick of using my own money to be "my competition's R&D department."
So I hope G35 guys and P+S and Hoodman and everybody else who spent money and time and attorney fees to get patents, make enough money to create more innovative products for me to consume.
Oscar, hehe- I was talking about the math in the post before yours, not your post. It probably WAS € 8,50. But at one point or another you did pay for all the stuff you had laying around. However, you probably bought it at IKEA so it was probably a good buy.
Rafael Lopes November 3rd, 2005, 01:32 PM Guys, I was deeply misunderstood. The reason why I used the comas is because what I meant by "breaking the patent" is that I think it's great to see that there are other options for people who cannot afford expensive equipment. I'm far from encouraging anybody to rob other people ideas. I think everybody knows that most of the time there is a reason why a certain product costs a certain price, hence most of the time they will not obtain the exact same results by chosing a cheaper option. But I like to know that the cheaper option is available. For instance, isn't everybody happy that the G35 is way cheaper than the mini35? I know that I am very very happy about it. The situation is the same with other products. I'm sure there is a lot of people who love the fact there is even cheaper alternatives. And just for the record, in my personal opinion I strongly belive that the G35 is the best adapter there is and I can't wait to buy mine.

Thank you Rafael,
Please don't take my post as an attack. I just feel strongly towards patent infringements and have spent the money to make sure that we are not doing that. There are other options for people who cannot afford the "expensive top of the line". That is what the DIY movement is all about. When you start selling a product that infringes on a claim that is when you get into trouble. To be fair I don't think you mean "Breaking patents" so much as developing cheaper more efficient methods. I know its semantics, but when you get into patent law it's ALL semantics. I would hate for someone to be labled as a "patent breaker" who is not. You dig? :)

You are only supporting "forget the biped walk, let's climb back into trees" as perfectly clear explained by Bill Porter in the post above.
Same was with Napster and followers. "Share" music instead of BUY a CD and the artists lost motivation to create. Rip of good ideas, turn them into "whatever", and offer them for a low price. The market will help the "turn back to stone age" buying the fakes. Was there anyone ever able to stop it? Not without a lot of bad blood and law suites and tons of money in legal fees.
Morals evolve with education. The closer to beast, the less moral. Bite before you get bitten, (and run with the dough). Could anyone argue with an alligator?
Some spend years on R&D and others still, or, unable to understand, come up with "their own inventions" and the market applauds them for how "smart they are" for the "short sighted interpretation" of ones work.
I might be a dreamer, but I still believe the good will prevail and all will act in the end as human beings. (or.. I might remain a dreamer)
Oscar Spierenburg November 3rd, 2005, 02:49 PM I started this discussion because we talked about the MovieTube. Bill and Jonathan say about the same as me in a way.
Rafael, only as long as people make something for their own use and share it on these forums, it's OK. But when more and more people are selling these things (unless it's an invention of there own like the FF gears of Dan) on these boards, I think there will be trouble some day. I think on the day when it becomes a real threat to the original manufacturers.
I hope (I'm sure) Jonathan doesn't mind me and others speculating about the G35 and microwax (back to the thread finally) and trying to achieve the same results, as long as we don't start selling a wax adapters. That was my point, back to the wax?

Well put, What makes you say we have a wax adapter? :P I love this speculation. It cracks me up :P
Jonathan-
Bill Porter November 3rd, 2005, 10:06 PM What makes you say we have a wax adapter?
I saw an unmarked jar filled with what appeared to be Mobilwax 2305 sitting next to an XL-2 once. MYSTERY SOLVED!!
Next up, is Loch Ness Monster a plesiosaur or a floating log??
Matthew Wauhkonen November 3rd, 2005, 11:58 PM Regardless of if it's microwax or not, it's got producing good images and that's what counts.
By the way, I think microwax produces far nicer images than GG in most cases (the highlights are handled in a nicer way, contrast is changed for the better) so I would be thrilled if the screen were microwax, despite the fact that this would mean the key element of a $1000 adapter costs under a dollar in costs and labor, potentially. If it works, it works.
Dan Diaconu November 4th, 2005, 01:56 AM despite the fact that this would mean the key element of a $1000 adapter costs under a dollar in costs and labor, potentially.
You seem to forget the thousands of $ spent and sleepless nights of many months leading to $1 screen THAT WORKS !!!!!!!!!!!
Bill Porter November 4th, 2005, 12:03 PM the fact that this would mean the key element of a $1000 adapter costs under a dollar in costs and labor, potentially.
Not a fact.
To mass produce wax screens means a huge investment in engineering and producing a machine to build them. Or, to do them by hand, means higher per-part cost. Either way, there is a lot more expensive infrastructure around making them. This means a hell of a lot more than $1 per screen.
Having a background in process engineering, when I have spoken with manufacturers of wax screens I have come away feeling their prices were quite economical. Nobody selling a $100 screen is getting rich, overcharging the consumer, or even making any money really.
Most retail consumers look at a simple part and make the same mistake of seeing PER PART cost and not the amortized cost of everything it took to get there. To offer anything as a business you need at least one person there full time. Add their salary into the mix. These are hard costs. I have seen this same mistake many times before. This gross misunderstanding is why so many businesses fail: people go into business assuming a per-part cost of $1 is $1. Really a per-part cost of $1, is unit cost X units sold per year / all expenses (payroll + rent + materials + equipment + advertising + inboound freight + marketing (if any) + electrictity + phones + taxes + insurance + every other thing that eats away at the bottom line). Try it, you'll see why most niche artisans like Dave Maxwell and his screens, are charging $200+ for a screen and still living a pretty meager life.
Oscar Spierenburg November 4th, 2005, 06:03 PM Of course your right Bill, but the whole discussion is not really of any use. It would be unappropriated for Jim to produce and sell wax screen on a big scale because Frank did a lot of work and research before him. It would be unappropriated for me to do it because Frank and Jim were doing it before me, It would be unappropriated for Matthew or anyone else here to sell wax screens because the point of these forums are to share your ideas. If suddenly people think: hey, that's a good idea, I can make money out of that!, then this whole forum is going the wrong way IMO.
I suggest to go back to the wax discussion, I'll be making a new one soon, so I'll sell...hmm..share my results next week or so.
Bill Porter November 5th, 2005, 02:04 AM Can I buy one for a dollar?
Matthew Wauhkonen November 5th, 2005, 07:03 AM I'll sell you one for a dollar.
Also, you totally missed the point of my post. I merely meant that it's funny how the least expensive solution can sometimes be the best, even in something with otherwise expensive parts. I don't consider $100 for a wax screen to be a rip off at all.
Ben Winter November 5th, 2005, 11:00 AM It would be unappropriated for Matthew or anyone else here to sell wax screens because the point of these forums are to share your ideas.
Who's to say someone is required to make their own wax screen if they want one? If someone's willing to pay enough money for a premade wax screen, I don't see why someone with experience in that area already can't say "Oh here, I'll make one for you and charge you reasonably for parts and labor because extravagant prices would scare you off anyway."
Oscar Spierenburg November 5th, 2005, 02:13 PM Ben, I was talking about people selling on a 'bigger' scale. Anyway let me put it this way, I posted a guide on the web on how to make a waxscreen. No one but me and Frank have succeeded (without dust and all), that's why I post the guide, so people can do it themselves and maybe improve the method, like Matthew or someone else. But not to have people making screens and sell them. Is that so strange? It used to be the spirit on this forum.
But that's not the discussion, I only said (some post up) if people are selling everything so easily, some day it will turn into a lot of trouble with the companies that own the patents.
Ben Winter November 5th, 2005, 03:19 PM Oh. Gotcha.
By the way, I've been experimenting with different options instead of wax that are a bit unconventional (sugar water, hot glue, scotch tape) but haven't come up with anything fantastic. I'm betting there's something out there that can beat wax or at least match it...
Oscar Spierenburg November 5th, 2005, 05:04 PM That reminds me, I tried hot glue too some months ago. One other thing I had in mind was resin, which in some conditions turns diffusive, but probably not between glass.
Mikko Parttimaa November 5th, 2005, 05:15 PM Hi, posting here for the first time.
Month ago I made my first test glasses with microwax. (which was unbelievebly hard to find, had to order it from UK) I wasn't able to find epoxy which wouldn't produce bubbles and I had a tons of school work so I stopped working with this thing for a while. Now im ready to start again. This is what I have this far:

http://hasu.kapsi.fi/Mikko/Microwax/Wax7.jpg
http://hasu.kapsi.fi/Mikko/Microwax/Wax8.jpg
Shot with f.1.4 50 mm Ricoh lens and a crappy Sony handycam. The glass is not correctly aligned and the condesors (two of them) need to be tweaked a little to reduce the barrel dissortion.
It has couple of those nasty bubbles in it but I find the grain (or the lack of it) great. It can bee seen if looked carefully but I can live with that.
Ill go look for better epoxy tomorrow so I can finally finish this project. It's funny how I (and all of us) have these three problems: grain, dust and bubles. I never have all of them, just one. This glass in the pictures had only grain after first melting. When I remelt it, the bubbles appeared. Cruel I say.
Oscar Spierenburg November 5th, 2005, 05:35 PM Nice to see someone new picking it up again! The images look very good. One thing I notice is a little reduced contrast, but I seem have the same thing with microwax. I think that's one difference (besides grain) with Paraffin which has more contrast (maybe because of the grain).
Epoxy shouldn't be hard to find, but maybe they call it something like: two component glue.
Also, to avoid those bubbles when remelting, but the whole thing in a small container of already melted wax, so there is no chance of air coming in.
Andy Gordon November 6th, 2005, 05:33 PM I use an epoxy called Araldite. Where did you get the wax from?
Oscar Spierenburg November 6th, 2005, 06:26 PM Make sure you check the right stores, microwax is used for candle making (try hobby suppliers) and Batik paint techniques (try art suppliers stores) I also think they put it in chewing gum, but that's of no use I guess, unless you can blow a bubble onto a piece of glass...oh, never mind.
Mikko Parttimaa November 7th, 2005, 08:17 AM I ordered mine from here: http://www.candlemakers.co.uk/textile/textframe.html
Yes, I had two component glue but there are differences in them also. Have to look for Araldite then.
Oscar Spierenburg November 11th, 2005, 05:49 PM Just because I want to make a new adapter for higher resolution, I thought I'd need to finish the first wax adapter, so that I can shoot work and test scenes with my one chip consumer camera (which is not a bad camera for that purpose).
The wax screen is without error, bubbles or dust, and I think as little grain as possible, unnoticeable under most circumstances. Here it is:
http://s01.picshome.com/a82/wax_adapter.jpg
Now I'll get on with a bigger wax screen for my double camera (which I talked about some time ago, and will explain when I get some results)
Besides that, I made a LCD projector from a 15" LCD and a OHP and the footage from the wax adapter projected on a big screen shows very much resemblance to 16mm film. I think the grain of DV resolution is about the same size.
Leo Mandy November 11th, 2005, 06:45 PM Bravo, Oscar. It looks great, as usual!
Dan Diaconu November 11th, 2005, 08:54 PM I second that. Bravo Oscar. Nice and clean, like a pin!
Bill Porter November 12th, 2005, 12:58 AM Good job! Keep it up, Oscar! I like seeing your experiments.
Off-topic I have another question. Do you guys really eat french fries - sorry, Freedom fries - with mayonnaise?
Mikko Parttimaa November 12th, 2005, 04:11 AM Of course we do. I only use ketchup if there is no other choice. Mayonnaise and -krhm- FRENCH fries are like red wine and good steak, they are just meant to be together. Eating them with ketchup is like eating the steak raw and drinking turpentine with it.
And once again back to the topic. Oscars adapter looks nice. It has this great guerilla (not 35) look to it. I also got my araldite and will be making a new screen as soon as the epoxy has dried. Instructions say it should take something beetween 18-24 hours.
Oscar Spierenburg November 12th, 2005, 05:16 PM I got a few emails over a period of time from different people who can't really figure out how to implement my guide using round UV filters. (In stead of straight pieces of glass)
So tonight I made some new pictures (just for the guide, there isn't even wax in the cigar case..hehe) and wrote a slightly better guide:
http://members.chello.nl/a.schultzevspierenburg/wax3.htm
Oh and Bill, I can only get French fries in YOUR Mc Donald's. How about that!
Kurt August November 21st, 2005, 02:53 PM Probably asked one thousand times:
Has someone worked with aspheric condenser lenses? Like these:
http://www.edmundoptics.com/onlinecatalog/displayproduct.cfm?productID=2454
Every image I see with wax adapters has this strange bokeh. Very round. I don't exactly know how to describe it. But I'm shure you know what I'm talking about and can also give me a good explanation.
Oscar Spierenburg November 21st, 2005, 06:46 PM bokeh? Good or bad?
I like it, although you are right about it being a bit circular (or round as you say), as if the condenser distortion only works on the unsharp areas.
I don't know about the lens you posted, it might be too thick.
Anyone know more about this? Aaron Shaw...?
Bill Porter November 21st, 2005, 07:33 PM I am not sure if you are talking about bokeh or something else, Kurt. Round bokeh is almost universally considered preferable, as far as I have ever read or heard. The fewer the blades in your lens' aperture, the more of a polygon the bokeh appears to be. Uuugly.
Aaron Shaw November 21st, 2005, 10:27 PM Ooh intersting question. I'm not entirely certain what effect an aspheric element would have on bokeh if any. Hmm, I'll have to ponder that. As far as I know there shouldn't be any effect in the out of focus areas that you don't see in the sharp areas. The only thing I can think of off the top of my head which might cause a difference is the angle at which the light from the 35mm lens hits the aspheric element (as it isn't colliminated when emerging from the 35mm lens). 35mm lenses use these often enough though that I doubt it would make any overly noticable difference. The fact that everyone shoots wide open all the time might have something to do with it since anything out of focus becomes much more obvious.
As for the lens you posted... "condenser" lenses are designed to be very fast so the thickness isn't a problem in that case. The problem is that with speed comes aberration. Unless you stay at the precise focal length of that element I suspect your image quality will go to crap (heck it might even do so anyway). The hard part is balancing speed with quality (in any system really). To get really fast optics that are clean you really have to go with custom designed and ground elements. Of course, the amount of aberration people see as acceptable differs from person to person.
Geeze it' been a while since I posted here! Always good to come back now and then. =D
Oscar Spierenburg November 22nd, 2005, 04:20 AM Thanks Aaron.
Maybe you know why the condenser lenses I use work so good. I took two lenses from from old optics. One front piece of a 135mm telephoto lens. One front (or second) piece of glass from a super8 zoomlens. They are both just big enough to use in front and behind the wax GG (like a sandwich). They are relatively thin.
I seems they strongly reduce each others aberrations.
Kurt August November 22nd, 2005, 09:05 AM About the circular blurred parts, Wayne pointed me to an interesting website where some explanation can be found:
http://www.vanwalree.com/optics/bokeh.html
Read: 'Shape of the blur patch'
Thanks, Wayne
Wayne Kinney November 22nd, 2005, 09:16 AM Actually, we need to credit Dan Diaconu for providing that useful link.
Bill Porter November 22nd, 2005, 02:49 PM Bill, I'm sure you've dealt with this before to some degree at least? As far as I know there shouldn't be any effect in the out of focus areas that you don't see in the sharp areas.
'Bokeh' only refers to out-of-focus areas. And typically, sharp areas don't show the same effects as in the out of focus areas, unless there is something really wrong with the optics of that make/model lens.
Theoretically, I think a lens' bokeh traits probably are present in the sharp areas, but let's think about the reason they're not visible: What is bokeh? It's a pinprick of light, a highlight, "blown up" to much larger size. In sharp areas, the pinpricks are still almost infinitessimally small.
Oscar Spierenburg November 22nd, 2005, 05:28 PM Yes, but Kurt seems to be right about the bokeh looking differently on these wax adapters. One of the reasons that I think the G35 has something waxy going on.
Unless it has something to do with the fact that wax can be made very thin, so you have the highlights reflecting on the condensers as well (just my theory though) . It could be that the G35 isn't a wax adapter, but uses a different diffusing material with the same thickness of the wax layer. I don't know.
Dan Diaconu November 22nd, 2005, 06:48 PM It's a pinprick of light, a highlight, "blown up" to much larger size. In sharp areas, the pinpricks are still almost infinitessimally small.
That's right, and they go by the name of... circle of confusion (cough, cough) make that diffusion!
Bill Porter November 23rd, 2005, 02:39 AM Ahhh, I misread or missed something in Kurt's post, perhaps. I didn't see the bit about bokeh looking different due to just the wax adapter. Interesting point. Oscar, if you or anyone has both a wax and a non-wax screen (such as ground glass), somebody ought to compare with the same lens!
Dan,
Now that was a bad one. LOL
Oscar Spierenburg December 4th, 2005, 06:25 PM Hey.. I just had a look at the new website of the Cinemek/guerilla35, but the first footage I played, montereyweb.mov, clearly shows a small amount of static grain on the shots were there is a lot of sunlight. All static adapters have the same thing when you close the iris, but we were told that the G35 was grainless. (I'm not talking about the large amount of compression artifacts)
So, whether it is a wax adapter or not, I can surely see (now) that it has the same characteristics. Anyway, it's not better than microwax....meaning that wax is the end of the static quest?
(there is some very good footage their site by the way, they should post some frame grabs)
Bill Porter December 4th, 2005, 07:28 PM I love that clip. According to SavvyPro's site it was a demo G35 unit from half a year ago. I know a lot has changed since then. Maybe Jonathan will chip in about how much different it is from current production units.
But, I don't know who from Cinemek said the G35 was grainless... ? I did see a post some months back where Jonathan said it wasn't totally grainless. But it sure is the nicest of any of the adapters I've seen.
I guess it is a subjective term too, because even film has grain, though not due to any adapter of course. The only thing without grain is... pure video?
Matthew Wauhkonen December 4th, 2005, 10:43 PM Moving grain is inherent to the random nature of light. Even your eyes have it. Everything does.
Static grain, of course, is due to the size of the pores in the diffusion screen.
Ben Winter December 5th, 2005, 05:02 AM I'm still clueless about how the Cinemek adapter could possibly be grainless in all situations if it's static. Someone mentioned using Sapphire around here as a focusing screen...
Anyways, all the details will apparently be released within the next few weeks, but from what I understand that phrase is wayyy overused over there.

Call it 'virtually grainless' or something, but this clip shows virtually grainy shots and some vignetting.
My point was, it's very good, but it seems to be the same quality as microwax. In the best possible conditions (cloudy sky?) the microwax is virtually grainless. Too much light would make you close down the iris and some grain will appear.

The common understanding to avoiding grain is that you leave the SLR iris open fully and use an ND filter or close the iris in the camera itself if there's too much light.
Matthew Wauhkonen December 5th, 2005, 09:08 AM Jonathan quoted no grain at f2.8, usable at f4 and at some cases f5.6, beyond that there are grain issues a while back...
Then HD got big, and grain become much more of a concern so apparently there are improvements.
It will be interesting to see....
