Do I get this right about S35?

[Pascal Parvex]

I checked the specifications in the pinned thread. So the Super 35mm Helium sensor is bigger than film Super 35mm and cannot be used with Super 35mm lenses to shoot with? Or am I mistaken?

It's best to check the individual lenses themselves. Most Super 35mm lenses actually do cover 8K FF on Helium.

I've compiled several lists of lens coverage, but this is a good starting point:

In terms of being true "S35", 7K HD is pretty "nail on the head"-ish if you are deliberately trying to match the exact format.

Just shoot 7K. Almost all S35 glass will cover.

Or basically, what Phil said.

So, in 7K, a lens would need an image circle that could cover 29.58mm. Do I have that correct?

And therefore, Sigma's 18-35 would be a tad too small?

 

[Paul Watt]

18-35 vignettes between 18 and 21ish at 8k. At 7K it has total coverage.

Simple solution - if it exists: use a teleconverter that increases the image circle just enough so that you lose no more than about 2/3 of a stop. 1.4x might be overkill.

I imagine it would be. Veydra does a 1.2x PL Expander and says it expands an image circle from 28mm to 36mm.

Thanks for all the answers guys.
