I have a Sony a7r III, and I have the chance to get a 28-200mm APS-C lens. I know this is a full-frame camera, but I also know an APS-C lens can work on it, but at what cost? Am I correct that it would crop it more (my understanding is that a 200mm would be more like a 300mm?) and would it also negatively affect the quality?


I don't know 28-200 APSC lenses that would become 42/300 equivalent....

but some 18-200 would be more interesting

Quality wise, you lost 13.3 Mpx, and 1 stop for noise at same final size
