Focal Length Ration on RED Cam

August 24, 2006

Just saw a very nice post on It shows the different areas of the CMOS that are used in the various format options of the RED cam.

For my Nikkor lenses this means in the Red S35 format they are extended to the following values.

24mm -> 35,40984mm
28mm -> 41,31148mm
35mm -> 51,63935mm
50mm -> 73,7705mm
55mm -> 81,14755mm
85mm -> 125,40985mm
105mm -> 154,91805mm

I also found that when using the Red 35mm format I can use Nikkor DX lenses and there is only a minimal multiplication factor. That means my 18-55mm will keep its focal length.
