35OPF18-1 20-120mm f2.5 zoom COVERAGE?

[Ilya O.]

Hi, fellas

Can anyone shed some light at the LOMO 35OPF18-1 20-120mm f2.5 zoom coverage on Red? 5K okay?

And as for Arri open gate?

Andy White once said "Portholes in 5K up to 70mm - so only usable in full zoom range at 4K"? Any more experience?

If anyone in the LA area has one, I'll be glad to project it for you and report on the projection measured coverage based on our reticle target.

PS probably works stunning with the 1.7X Red Vistavision / Full Frame expander that Duclos is selling - that thing is tack sharp for an extender.

Hello Ilya, i don't have any red around me, but have shot various films with this zoom.
In my memory it vignettes seiously in 5K...1,66 format was the widest possible.
Concerning ALEXA i have shot recently in 16/9 without any trouble but i can't say anithing about OPEN GATE, but i'm quiet certain that it will vignette a litlle bit.
