Yeah got the letus a couple of days ago - the economy. I'm still learning the ropes and testing it out...but so far I've been able to get some promising results. It's very very sharp, although the light distribution isn't completely even is what I've noticed. It's only a small, niggling fault though, and alot of adaptors are plagued by that to some extent or another. Will post footage when I'm satisfied with my results.

just recieved mine yesterday. Its heavier than previous FE version.

Malcolm if you need even light distribution you would need to get the Extreme version as it has a added condenser glass for even distribution of light.
However for me i like the slight vignetting look to it especially for filming wedding.

Hmmm, been doing more tests with it. I've managed to secure it properly to my camera, and I've adjusted it well enough. I've more or less killed the vignetting in most situations - it only appears in situations that are too dark. Other than that its great!

Hey Malcolm, great that you have got it working. Can you post any screen grabs or sample clips?

Here ya go: http://www.mediafire.com/?8tyxe2msim9
Its a 47mb quicktime file, shot using a nikkor 50mm f1.8 prime, using available lighting. The footage from my initial tests is at the start of it, for roughly 1 minute, and yuo can see the heavy vignetting. After i tweaked it and made some changes to my DVX scene file, i shot more stuff and i think it looks alot better now. It's still got a bit of vignetting, i think? But I'm not really sure - its like its there, and not there. I guess its more apparent when the shot is a bit dark, but then again it's really minor, and you'll only see it if you're really looking for it. I didn't bother editing any of this, so i just dumped everything i shot onto my timeline. I just wanted to check out the adaptor, so pardon the poor footage quality. I tried to cover as many scenarios as possible with this.
Notes:
The quicktime compression is great for retaining the sharpness of the shots (and i am very pleased with the sharpness of this adaptor), but it seems to wash out the colors a bit, and the gamma is a bit lighter. The actual shots are a tad less washed out, and slightly darker.
As for the shakiness of the footage, this bugger is really hard to keep steady alone. Grrrr. Heavy too - gonna needa figure out a new technique to keep it steady while handheld...When my 18" rails come I'm thinking of putting a counterweight at the back of it. This way it'll shift the centre of gravity back to the handle, and it'll make it more stable as well. It'll also tone my biceps.
Also, one thing i realise about using a still camera lens to shoot with is that it's really prone to hazing when pointing at sunlight, etc. Footage can get washed out by excess light pretty fast in relation to the camera lens alone. Probably see if i can diy an ersatz mattebox to shade my lens when the rails arrive.

Hi Faiz what camera are you using? is it possible to post some footage?
So far it work beautifully on for me.

Thanks Malcolm. I'm downloading it now, but looks like it'll take a while.
Yes when you add a matte box (which you will need for sure) it's going to be really front heavy. Tripod is the obvious answer, but if you need to go handheld you better start working out man!
Looking forward to see the footage, will post again later when I get the chance to see it.

A few observation i have realise when using letus.
1. Make sure you turn off your autofocus on your camera.
2. Make sure you zoom-in enough so that your GG edges is not seen.
3.The vignetting occurs usually because we did not zoom-in enough.
4.Turn off your OIS.
5. Try not to shoot with back light. remember you are using like wide open f1.8 light spill from backlight tends to occur furthermore of DV or HDV ccd are smaller than film cameras

Yeah, that's what i learnt. I'm not sure how much to zoom in though...with the current test i'm zoomed in at 75 on the DVX. Not sure if i should go in more - i wanna stay as zoomed out as possible so that i get smaller grain and a wider field of view - the 50mm becomes quite tele otherwise.

Yup 75 for dvx is sweet. you should not have serious edgy vigenetting unless you use 24mm but even when i use 24mm the vignetting looks very smooth and nice.

Nope, no serious edgy vignetting right now. Only the occasional hint of it, but like i mentioned in my post, it only appears sometimes, and normally when the image is underexposed anyway

I don't understand. Your set is my set. And I'm fine at 75

The footage looks really good Malcolm. It takes away the video look and gives a totally different feel to the image. Wonder how it would be on my A1, I think it is not as good in low light as the DVX.
MalcolmOng

You'll definitely get the same filmic image, but yeah i guess the light sensitivity is dependant on your camera. I used it a bit with the A1, and it gives pretty acceptable light loss, actually. And that was before i properly calibrated it. Now that i know how to work this baby, i shuold get much better results with that combo. Speaking of which, check out the VIVIDRGB preset for the A1. It's floating around DVXuser or DVinfo. It's really good - really makes the colors pop, if you don't already use it
