I am going to shoot a feature on 35mm using Anamorphic lenses and my camera has a "Full Aperture" gate.
The camera, of course, is set up for regular 35mm not Super 35.
Will everything be ok with this setup?
Thanks for your help in advance.

Yes, as long as the lens is centered for regular 35mm, not Super-35. Most cameras set-up for regular 35mm (1.85 / anamorphic / Academy) leave the gate Full Aperture anyway.

Shoot a framing chart that matches your camera's groundglass markings and project it to make sure your lens is correctly centered for the anamorphic projection aperture.

I presume that you are renting this camera, in this case it's usually just a matter of telling the rental house that you are shooting anamorphic. They usually take care of the rest (at least in my experience). There's some little adjustments that need to be made (video tap and viewfinder that unsqueezes the picture, donoughts, etc...)

Standard SMPTE 59 specifies the 35mm camera aperture image areas and uses. When shooting anamorphic, the "Style B" aperture is specified, which is 21.95 x 18.59 millimeters, centered on the "Academy" centerline that is 18.75 millimeters from the reference edge of the film. But as long as the centerline is correct, you can use the larger full frame "Style C" aperture of 24.92 x 18.67 millimeters, since the unused area of the camera negative (where the optical soundtrack is printed) is not printed anyway.

Depends on your end format or post process. if you're aiming for a contact print and a traditional release print then N35 centering would be the right way to go. If you're going the DI route, then there's no reason to not S35 center it. Gives you extra leeway on the sides (2.66:1 recorded on the neg, so you can extract 2.40:1 from the center but be able to slightly repo the image in post horizontally).

I've shot many shorts on anamorphic w. super-35 centering and it works just fine.

Ok. So everything is fine.
I plan on a contact print.
We do own a camera that has a full aperture gate.

Thanks for all your help.
