7. Your camcorder/macro to 52mm stepping ring - $5.00

+ Spanner wrench to screw retaining rings tight enough but we managed to tighten them with philips head precision screwdriver.

TOTAL: $170.00 (+20% for EU) for static one
Add $40.00 for vibrating one as it requires vibrating screen holder, vires, plugs, switch, battery and so on.

I must warn everybody that shipping costs could be as high as $65 for Thorlabs parts delivered to Europe.

This estimation doesn`t include camera specific achromatic macro or closeup lens as smaller Panasonic cameras don`t need any.

Assembly time: 3-30min depends on getting the correct flange focal distance (http://en.wikipedia.org/wiki/Flange_focal_distance).

Not that bad for the most versatile static DIY dof adaptor for Nikon lens, no glue required.

See here for sample footage with EE-S screen: www.cinedof.com/static/

With minor modifications to focusing screens and reduced viewable area this design can be used for vibrating assembly too.

and possible for Canon EOS ?

thx

Vibrating screen holder reduces almost any visible noise but is more complicated specially wen used in cheap macro tubes.
Static or so called passive one is easyer to complete and operate but any dust on focusing screen will be visible.

Sheap macro tubes can be used for adaptor housing but make sure of which inner diametre they are before ordering any or order those tubes before ordering our screen holder.

Frensel focusing screens such as EE-S and EE-A don`t need additional PCX lens. EE-S is focusable via on-board monitor.
Sanon EE series Screens can be sanded down to fit vibrating screen holder that fits to thorlabs tube.
HANDLE FOCUSING SCREENS WITH EXTREME CARE.

Thorlabs components are the best choise for static solution but more expensive than scheap macro tubes from eBay.
Thorlabs components can be assembled and tweaked with ease but you can not use full viewable area in vibrating assembly. You can align thorlabs components, focusing screen and lens mount to your camcorder with ease via SM2T2 coupler. Thorlabs 2" tubes can take 50.8mm diametre screen holders.

EOS mount can take almost all 35mm lens via lens mount adaptors. Canon EF mount can take Nikon, Pentax K, M42, Olympus OM, Contax/Yashica and Leica R for example. FD to EF mount adaptors are also available from third party providers but image quality might degrade because the nature of FD adaptor.

Specially designed anti reflective vibration motor can vibrate at half power (1.2V) to reduce audible noise and to increase bettery life and service life.

DO NOT USE SUPER GLUE!

Hi Toenis,

I have PMed you regarding the use of the leaf spring GG holder. Did you get the mail. Please get back to me regarding my comment and request. Following my last PM, I really don't mind compensating you for the use of the design. Say for every purchase I pay you USD5.00 and maybe this deal is limited for the next 50 purchases. PM me on this if you have no problem. Since you showcased this leaf spring GG holder first, I think its only right you get credit for it too. What ever it is, just PM me and we can discuss further.

Would it be effective to use one of the Thorlabs Ground Glasses in your screw-together static design using thorlabs tubes?

http://www.thorlabs.com/NewGroupPage9.cfm?Guide=123&Category_ID=185&ObjectGroup_ID=1132&Visual_ID=546

I'm not sure what kind of results people have recieved with these. My guess is that the advantage of the Canon focusing screens would be the build in fresnel, correct?

I have used Canon EE-S and there is a very weird double-ghosting artifacting occurring around the center, near the edges. I suspect it is from the fresnel design. I am also suspecting it also occurs with the EE-A as well. I suggest against the use of them.

Ben, Toenis has posted earlier couple samples with EE-A or EE-S(or with both). There wasn't seen any ghosting.

All moving images found on: http://www.cinedof.com/static/ and http://www.cinedof.com/test/ are taken with EE-S screens if not noted otherwise.

Frensel rings can occure in static design but when screen is installed so that frensel side faces slr lens they are not visible any more.

EE-S screen has some uncommon character when exposed to extreme lens flares - microlens pattern becomes visible. Here you can see the worst what can happen (http://www.cinedof.com/test/EE_S_microlens_lens_flare.jpg) and here can you see flare fom wide angle lens aimed directly to sun (http://www.cinedof.com/test/EE_S_oscillating_19mm_f4_01.jpg)

Hey Toenis,

I have a question regarding your creative commons licence, what is exactly does it protect you from?

On the subject of camera focusing screens.....An SLR camera consist of an CCD or CMOS which captures the image from the focusing screen, which captures the image from the lens. The SLR is static, any the image comes out hi-res with no problems so why does this not happen with the DIY adapters that use focusing screens?? In principle all you are doing is replacing the SLR CCD or CMOS with the camcorders CCD's. So why do the images come out so differently? Is it all in the presision that DIY adapters cannot achieve?

Maybe Bob Hart can answer this, after all he is the information god, who needs google when we have Bob. (Im not being sarcastic by the way Bob, I read through your replies all the time and they are very detailed and informative, keep up the good work).

Thanks,

Are you talking about a digital SLR? Either way, the mirror and GG are only for the optical viewfinder preview, and are bypassed once the shutter is released (mirror flips out of the optical path). Or am I missing something?

Yeah digital SLR. Doesnt an SLR record what is being projected onto the focusing screen? I thought that was the whole point of the focusing screen. The mirror/focal plane shutter opens and the image is projected in the sensor in exactly the same manner as on the focusing screen. I maybe wrong.

Tony,

The focusing screen is only for the viewfinder and setting focus ('focusing' screen). In an SLR (Single-lens reflex) the light from the lens is bounced 90 degree's up off a mirror and then projected onto the focusing screen, then through a roof pentaprism giving you the image in the viewfinder with the correct DOF and FOV.

Once you have set your framing, exposure and focus, once you press the shutter to take the photo, the mirror flips up out of the way, and the light from the lens projects directly onto the film or CCD in the case of a digital SLR.

http://en.wikipedia.org/wiki/Single-lens_reflex_camera

Most digital SLR's CCDs are smaller then true 35mm so there is a cropping factor.

Are the pentaprism too small from a camera body to be used for the dof rig application of flipping?

Yeah sorry, Ive got my diagram round the wrong way, the number arrows are weird, instead of bullet pointed numbers at the beginning then the description the numbers are at the end of the description with the next one next to the number, very confusing.

But ok if we view through the prism - condensing lens - focusing screen - mirror - lens assembly then wont this work........

Forget the prism and mirror as they are only for projecting the image the right way through the viewfinder.

Say the camcorder is the eye looking through the viewfinder then it passes through the condensing lens and focusing screen then through the lens assembly shouldnt the image be perfect providing the distances are correct etc. Or is it just that our eyes dont see the grain but the camcorder will, thats probably it isnt it?

While looking through the viewfinder, the lens is probably wide open all the time so that means less grain, also, depending on the focusing screen, the ones that have extremely fine grain are usually no good for an adapter, since they do not diffuse enough for that purpose, giving ugly hazy bokeh.

So has the Canon EE-S screen or any other screen setup been perfected on Toenis's holder as people have said that ghosting and artifacting occurs. When it does work is there a noticable difference between the static and vib setup? Is this a suitable solution for 35mm filming or does more research need doing. I only ask as whilst waiting for patent filing I have taken an interest in the other threads in this forum.

See here (http://www.dvinfo.net/conf/showthread.php?p=574284#post574284) for EE-S screen evaluation and latest tests

Toenis Liivamaegi

Here are a few still shows taking from footage using:

the panasonic pv-gs300
a adapter made using the Canon EE-A focusing screen, a 10x asian macro, and the Canon EOS extension tubes

I took plastic from a cd case to make the holder. With a better holder, like you vibrating one and a better macros, I think this would be a decent adapter.

I'm posting the still to show another POV, as far as using the canon EE-a Focusing screen.

I do have one question. do you accept paypal?

Paul, I assume that your design was static and matte side of the EE-A screen was facing your camcorder lens? BTW I have sent you an e-mail too.
Why are you using 10x macro on Panasonic GS300? As far as I know it should focus on 35mm frame without any resulting in much better image quality and edge sharpness. We have tested it with GS150 and GS500 without macro and it worked well, no chromatic abberations or edge softness. Even HVX200 almost made it without macros, but almost.

Regs,
T

Toenis, I have sent you an e-mail regarding using paypal as a method to purchase one of your screen holders.

I have a pretty interesting DIY concept that I thought up using some PVC Tubes. as opposed to the thorlabs tubes. I just need a screen holder and one of those EE-S Screens.

Yep. I can't get the moneybooker account working too. There's no way I can send you the money.
Can we use paypal for payment? It is much more common and safer than moneybooker i think.
If you do. I could make my payment immediately.

Moneybooker.com keeps telling me my transaction failed. Paypal is your best bet. I've been veried for five years or so.

**WARNING**

Be careful with moneybookers, I and many people have been getting dodgy emails from nigeria claiming to be from moneybooker.com. They ask for your details and stuff and steal your money. Theres loads of scams like this so be careful everyone!!

Yea Toenis.
You want the cash and we want the gg holder.
Let's get a Paypal account and everyone is happy. :)

We are using PayPal every day but unfortunately only for payments as it is not allowed to recieve funds when merchant is registered in one of the new European Union countries like Estonia.

It seems that only problem with Moneybookers is with customers with middle name or the like are being rejected by the system. As this is major problem for our business we are doing our best to solve it.

If someone knows better alternative to Moneybookers, besides PayPal let me know.

We are accepting IBAN transactions within EU.

BTW Tony, it seems you have never dealt with Moneybookers money requests so please don`t disinform potential customers.

Best regards,
T

Toenis,

How was I disinforming potential customers? I was purely making people aware of fraudulent emails that are currently circulating with people claiming to be moneybookers requesting details for supposed money transfers that dont exist, this is not disinforming. And for your information I have used them before, their office is about 200ft away from mine I actually know someone who works there and they too are aware of this problem so please dont assume.

The link below is a screen grab of many fraudulent emails I and many people I know have received supposedly from moneybookers. It says the payment is from moneybookers 3@mercantrade .com. mercantrade.com is an african registered domain used by many nigerians and other africans.

http://www.geocities.com/anthonyrelph/moneybookers.tiff

All I know is that my customers security and safety comes first when transfering money. Your priorities many be different. I was trying to do a nice thing and warn people JUST INCASE but I shall not bother in the future if thats what people want.

Hi Paul,

The 5 images above, what adapter setup did you use, static or vibrating?

Not bad images, the odd speck on the screen but all in all not bad.

Hey Tony,

the design was static. I'm working on a vibrating model . the problem is the gg holder. If I had a good gg holder that dampens the sound and localizes the vibration I would have no spots. Hence, my interest in this forum

please share any info on the matter.
