I hope I am in the right forum for this question. I have an X-t10 camera, and am thinking about getting an older manual everything lens or a superzoom camera such as the Panasonic FZ300 camera for "static" bird and small animal pictures for printing ( 8x10 8x12 16x20 ) nothing bigger. The size of lens I am thinking about would be in the 300mm focal length. I do not know anything about cropping, but which would be the best way to go for prints, a small sensor camera with up to 600mm reach, or maybe a 300mm- 400mm lens and crop? I hope I have explained it correctly. What are the pros and cons? APS-C or small sensor? Thanks for your input.
