Many of you have or have had a crop sensor camera and a full frame camera. Asking specifically about portraits: Do you see a huge difference? Does your lens choice vary that much? Say a person has an EF 85mm 1.2L or EF 200mm f/2L... would you hesitate to use those lenses on your crop sensor camera for portraits? Maybe someone has examples of those two lenses on both a crop and full frame camera of the same subject? Thanks!
