I am using a Sigma 8-16 APS-C lens on the SL to shoot 4K video.
Is there a factor involved?
Does the Sigma 8-16 become a 12-24 when using it with the SL switched to APS-C.
I know when I use a full frame lens, and I am shooting 4K my frame is within the Super 35 area. I have a crop factor of 1.5, (or 1.6 ... I am not sure.)
The Sigma, by the way is a nice lens .... but I think I want the Canon 11-24 f4. I want a constant f stop. I don't like variable aperture.
