Hi canon community, I'm very new to cameras and photography in general and was looking into getting a canon film camera but I was wandering if I will be able to use modern lenses (specifically a 12mm/10mm fisheye) have there been any significant thread changes or will it be a problem that it's meant to be used with a dslr? Thanks in advance.
DSLR cameras do not use threaded mounts, which means their lenses do not use them, either. There are a handful of adapters on the market that allow for the use of older, threaded lenses on modern cameras. But, not so many that allow modern lenses to be used on older threaded mount, camera bodies.
The Canon EOS mount is a bayonnet mount that uses several electronic "fingers" to create an electronic communication circuit between the camera and lens. This electronic communication is what allows for digital electronic control of the lens' focus and aperture. This communication is at the core of the ability of today's DSLR's to automatically focus and track subjects..
