Is the aspect ratio almost the same if I'm at a 50mm focal length on an slr lens vs. super 35? Thanks.
The lens doesn't determine the aspect ratio - a lens projects a circular image. The gate and later cropping determine the aspect ratio (the ratio of height to width in a rectangle). The lens determines perspective and field of view.
If you're asking if a 50mm has the same field of view on a 35mm SLR versus Super-35, the answer is no -- the 35mm still camera format is 8-perf horizontal and the 35mm motion picture format is usually 4-perf vertical. So a 50mm lens behaves more wide-angle on an SLR.
As far as aspect ratio, the 8-perf 35mm still format (same as VistaVision) at Full Aperture is about 1.5 : 1, whereas the 4-perf Super-35 aperture is about 1.33 : 1.
