s16 lenses shooting 2k. FOV difference

[thomas-english]

I am considering buying a RED camera. All my glass is s16 for my sr2. When I am shooting 2k with my RED and s16 glass will I notice a FOV difference relative to my arri sr2?

When shooting high speed 2k will I notice a difference relative to my s16 arri sr2 gate?

The literature seems to indicate that I can shoot a proper s16 gate on the RED however forums and further advice seem to indicate that I can't.

Please enlighten me!

There will be a little FOV difference. Super 16 camera aperture is 12.52 mm wide and RED 2K is 11.06 mm. So your lenses on S16mm film have about a 13% wider FOV. (Projector aperture for S16 is 11.76 mm)

These dimensions are for the open gate of s16.

It sounds like this is going to be around the same relative to the commercial ground glass I use. 7% on each side.

I found that some S16 lenses, the Canon 8-64 for example, can deliver a higher FOV on the Red until it vignettes than with a S16 Camera. But for this you have to shoot 3K RAW and crop later to something close to 2.5K RAW.

In order not to shoot to much uneccessary "flesh" I use 3K RAW 2:1. Cropped 3K RAW to 2.5K RAW has also the advantage that a full debayer with a debayer factor of approx. 0.75 - 0.8 will deliver full 1080p which 2K RAW does not.

Taking all this in account, the Red is a heavy but nicely working digital "S16" camera which can deliver pristine full resolving 1080p HD.

Thanks Hans.

How much are you having to zoom in on your monitoring? I have a Marrel frame lines generator and I think my transvideo does frame lines.

Shooting 3k for s16... easy to work with?
