hii Jared .
I am use 35 PS technick for first time (Waste money and so drop / light loss ) , than redrock , but for this time i m very comfortable with LETUS ULTIMATE
Actualy, the excellence picture appear from LENS PRO RELAY , so i can control the shutter and Irish independtly
On letus Ultimate you will get the Achromat lense, so possible for U to avoid the distortion of the lens and vignete shadow on the sides of frame.
I have some of refference when I shoot music video by letus ultimate
(about letus ultimate and PRO relay lens)
music video
thanks
