Hi all,
I put my new toy to use. A Letus Extreme 35mm adapter. Iv been building this system up for a month or so, acquiring bits and pieces here and there.. Rail \ shoulder rig, 7" monitor etc..
Here is some mostly hand held test footage

most shot with canon 50mm 1.8
The swing\tree shot used a 80 \ 200 zoom lens I picked up at a pawn shop for $15.
Around :25 you can see me ratchet down the fstops on the 50mm lens.
The shot of my daughter had post exposure added.. so some grain is from that..
So far, I can focus with the monitor, I can clearly see that Im OUT OF FOCUS, turning the lens is hard part.. lol.
I need to make and adjustment to the Letus to fix the back focus (focus measurements are off, infinity focus is too "soon")
Opening up the DOF, by stopping down the lens is difficult, particularly with a vibrating adapter as once I go past f5.6 I can see the grain in the ground glass focus screen.. so for deep DOF, the Letus will have to come off
(I guess spinners dont have this problem)
In my other testing, I really see what people mean when they say each lens has a sweet spot. For the lenses I have, that sweet spot is NOT at the wide open aperture, so the need for faster lenses is even greater (also being able to stop down to increase the DOF is a good thing, trying to stay in that "RAZOR THIN" focal plane is tough!
I have lots of learning to do..
