ex3 and letus ultimate
on Jul 25, 2015 at 6:04:25 pm

Hopefully some of you guys have experience with Letus adapters and the ex3.

My setup is ex3 + letus relay (academy frame) + Letus Ultimate + Rokinon DS Cine lenses.

It looks like I am getting good focus on the ground glass but no matter what I do I can never get good focus with the Rokinon's on and the image quality is terrible. I followed the instructions to set back focus (for infinite focus) with the back focus ring on the letus but I can never get good focus. As I turn the ring it will get a little better then as I continue to turn it get worse again.

Guy who sold me the ultimate said it worked fine with his hpx200.
I cleaned all the glass. Called Letus and they were completely unhelpful. They told me to losen the 3 screws that hold the spinning glass and move it until it gets in focus. That had no effect at all.

Anybody have any ideas for me?
