What's the best camera setup for sports and wildlife .. full frame or mirrorless..I have a Panasonic g80 with pan 100-400 lens, but I'm disappointed with the results. Cropping seems to make the pic worse, is that down to my 16mp sensor on the g80? Should I change for a full frame such as the nikon d810, 36mp ,would that improve things image wise while cropping. It may well be user error. But I'm thinking I need more detail im my pics.
