It's hard to find a perfect sunny day in Oregon this season. I manage to take my camera when I go to church today and have a couple of minutes at the park nearby. I will try to upload some seconds when I get home. No firewire at church, thanks for your patient.

Both files are the same thing, just make the smaller file for people having difficulty to download larger file. Couple of minutes is too quick for anything nice. Full resolution mpeg1 file. I am sorry if you don't like flowers, thanks.

This is my first DVi post, so go easy on me if I say something really stupid. I am a still photographer who is interested in using my assortment of Nikon lenses to improve the quality of my videos. I read a lot of posts about the importance of having high quality glass on the subject side of the GG, but wouldn't obtaining the best relay lens possible be of equal value? Has anyone considered using a 35mm macro lens as the relay lens? These lenses are optimized for close focus, and have an aperture adjestment...would this be equivalent to iris adjustment in video. I have not done any tests, but I would think that a macro lens would be better suited to focussing on a GG at short distances than a 16x or 20x zoom, which has more elements and is designed to cover a much broader range. It would also address the "leaf blower" isse of hanging a shooting lens and Letus on the end of a long zoom. Any comments?

the non xl versions of the letus use a macro and the 16x lens. the relay lens does away with both of them. a macro by itself can not do the job of a relay lens. also it would have no focusing abilities or iris control

quyen... one thing that just hit me... is it pronounced like :LEETUS or LETTUCE?

Quyen.

If you are looking for easy materials to make a pin lock for the Nikon mount, have a look at the needle rollers out of automotive drive shaft universal joints.

They are chrome finished and have rounded ends which should not gouge the aluminium on back of the Nikon lenses. One of those, in a hole drilled right through your Nikon/Canon reversable mount might do the trick. You would need to have a simple flat leaf spring about 1.5" long, fastened at one end to the case to push the pin forward.

To stop the pin from falling out through the hole you would need to have something like the small electrical screw and clamp wire connectors you find in electrical switches, clamped on to one end or a simpler piece of plastic tube pushed over one end and tacked with glue.

A few little scratchmarks from a little grinding disk on a Dremel cut into the end to be glued should make sure the piece of plastic tube stays put.

There would have to be another button in the case to push against the flat spring so the pin gets pulled back in to release the lens.

I did not engineer a pin lock as I found that using the Nikon circular spring alone was enough for my purposes. The spring also keeps the lens flange firmly against the mount face.

Your dual purpose mount would have to be re-designed into two pieces to accommodate the Nikon spring and there would then be no advantage from a manufacturing standpoint to doing this over making two separate mounts for Canon and Nikon.

The method I described was the way I was going to go about making a pin lock.

There are also very useful little coil springs inside of every disposable cigarette lighter which uses a flint and wheel. The spring is under the little flint which rubs on the wheel to make the sparks to light the gas.

Quyen, would you kindly shoot something in 16:9 and upload? Would be awesome to see =)

Sorry if this has been asked before: does the flipmodule degrade picture quality?

Andreas Rylander

I don't have XL2 to shoot 16:9, my betatesters will do that for you.

Christian Schmitt

I don't think of any quality issue with flipping, just little bit of light loss, thanks.

Quyen

What could possibly be the issue with 16x9? If all the other canon XL series lenses work fine with the XL2 in 16X9 mode why wouldn't the relay lens work properly? The 16X9 ratio is derived from the chips in the camera not the lens. The XL series lenses even work with the new XLH1(albeit not resolving as high as the camera demands). It would seem to me that the flange distance and the lens diameter is the same for all Canon XL series.

I don't think it would be a problem at all, but I'll post some results once I get my Letus35XL.

Is anyone planning to use the Letus35XL with the new Canon XLH1? That is the footage I really want to see.

Quyen, just let me know when the Letus35HD100 is ready. My money is ready. Thanks for the great work. Just got my upgraded Letus35flip and it seems great so far.

I ordered the LETUSXL last week and will be posting footage with the CANON XLH1 and the CANON XL2.

ill be posting xl1s

Hey guys,
I look forward to seeing the XL2 footage especially, and the H1 footage will be an added bonus.

Quyen,
One question ,can the adapter be sent back to you guys to be fitted for another camera?

For example ;lets say I got the xl adapter ,then down the road I got a jvd hd 100.Could I send the adapter in to get it fitted for that for an extra charge?
Or would I need to get a whole new adapter?

We have 2 xl2s now.
We might be getting in a HD100 though in a few months.
Im not sure.

Definitely like the hd100 a little better.

I am making HD100 adapter now. The XL and HD100 are quite different in design, so the adapter for HD100 camera is the whole new design and cannot be interchanged with XL parts. If you want HD100 adapter, I think you should wait another month, thanks.

Sorry if this has been discussed but I don't have time to read through all 116 posts.

I love the mini35 concept, I just wanted to know if by buying either of the adapters will render the Canon factory adapter for still lenses obsolete?

Obviously these adapters do more than just fit the lens to the body.

Haven't bought the Canon adapter yet but it was on my list.

I would say it was obsolete before it was made. Yeah it allows you to use those other lenses, but it does nothing for the DOF, and adds 7.7x magnification to your zoom. Unless you're shooting from large distances and need to zoom in a lot, I'd reccomend not getting the Canon adapter. The Letus35 will allow you to mount the same lenses, but take advantage of all their 35mm properties like DOF.

once this comes out my 16x lens will become absolutely obsolete as well.. i havent shot once without my letus since i got it.,

Hey Quyen,

I was looking at the footage and I just had a quick question. I have a mad slow connection so it takes a while for these things to load but as i was looking at the beginning second or so it looked really soft, and i was kind of disappointed, and then the next second loaded and there was this, what looked like, a fade transition, and then it was crystal clear. My question is just what was going on with the beginning.

Also, a request to the beta testers. can you guys do some resolution tests against the stock lenses (16x and 20x and what ever came with the H1).

So far the footage looks really good (cept for that first second or so) and im pretty excited.

when i get mine ill definately be doing tests against the old letus using the 16x and the 16x by itself.

Quyen,

I was curious, and maybe it's been posted already, but how much light loss is there in regards to the Letus35XL? Is it 1.5 stops like the Letus35Flip Enhanced or less?

Thanks :)

quyen... one thing that just hit me... is it pronounced like :LEETUS or LETTUCE?

Hey Andrew, I'm assuming it's Let - Us - 35 (it).

Am I correct Quyen? If I'm correct, I'm assuming I'm getting a nice prize. :)

Can't believe I brought the Letus35 and have not used it yet! Of course, it hasn't been the best weather conditions, lately, in Washington...Yeah that's it.

I lie, I just havn't played with it yet. I've shown it around to people and looked at it but havn't shot anything with it. Plan was to go shoot some nice footage in Korea, for my vacation starting this weekend.

However, I'm thinking of not taking the Letus35Flip with me. I'm not too sure how the airport security guards would react to it, that and I don't want to have to open and show it to the guards at the checkpoints, repeatedly in Korea and on my return trip. What with the recent news about airport baggage losing and damaging gear in the bags on the rise...Am I worring too much I just have a feeling the system will be damaged. I should worry more about my FX-1. :)

Oh well.

take it on the plane as carry on.. im bored here.. just moved to halifax and living on then navy base.. getting some awesome shots in my room though :)

cant wait until the 35xl arrives back home.. ill have to make the 4 hour drive just to pick it up.. well worth it.

Tony Tibbetts

I don't find the good way to measure light loss of the relay lens. With the regular unit, I can compare with and without the adapter then calculate the difference between the 2 figures. With the relay lens, I don't have anything to compare with. Can anybody help me on this? Thanks.

Quyen

it depends how wide your opening the iris of the adapter. At the widest, you're not loosing more than a stop of light. I think that you're not loosing .5 stop because there is no longer the XL HD lense in front of the adapter. I would say it depends. The thing is more you're closing the iris, the better the quality of the image.

Guillaume

Quyen, in your opinion is the relay version proving to be sharper than the version that uses the standard lens?

Are you planning on posting any more footage or stills?:)

So in theory, light loss would be less than 1.5 stops fot the Letus35XL since the light loss for the Letus35Flip Enhanced is about 1.5 stops.

Tony Tibbetts

Letus35XL is less light loss than the Letus35 Flip Enhanced, thanks.

Quyen

Hello Quyen,

How long do you anticipate the beta testing to last? Any info. will be appreciated.

My beta testing program is to develope the next generation. So it's likely will end when the next generation is about to surface, thanks.
