Well, I had my lens on F5.6 (All the Elite can handle). The Letus was on and everything on the scene was close to infinity. The only diference between the Extreme and the Elite is back focus. I think you can live without that for a while and buy the back focus later.

it's the elite worthed ?
or just pick a extreme sir?
what advantage with letus elite sir ?

thanks for info.:)

Sure it is worthed. It has back focus adjustment and better achromat lens. These features aside, it is just and extreme on esteroids. If you buy the EX1/3 optimization kit you get the better achromat. But as I said before, you can live without some features for a while and buy the addons later.

We Agree with your comments fully.

i can't believe a 135mm lens comes off with visible vignetting, moreover lensvignetting itself is circular...all the vignetting of the letus adaptors result from the square ground glass window...so it is quadrangular.
i used the letus for a commercial and the vignetting is just unnatural...but ok it's the best adaptor for the ex1 or the ex3. i also tested p+s 35mm adaptor and the biggest problem is that you can't stop down to F4 without making the ground glass visible...and i hate to use lenses with a wide open iris. anyway i achieved the best results when i fixed the zoom of the ex1 between 40 and 81mm and stoped down the 35mm lenses to T2.8 on a letus extreme...

Maybe you're right, but it doesn't seem to vignette when there's no lens on the Letus, just looking at the gg.

mhmm...

Hey Lukas, I tried to film it pretty flat, so I could play with it in post.
Settings I remember by heart:
Matrix Off, Detail On at 0, Gamma Cine 4(Interiors) Cine 1(exteriors), Black -3, Shutter at 180, Gain 0. I might have tweaked the gamma levels and low key saturation, but I really don't remember.

You would probably come out well with the cameras you mentioned with proper color correction, maybe with less background defocus.
I think letus have mounts for almost every lens and you could use yours. Tanks for watching.
