Certainly the increased field of view on full-frame can be advantage in framing some targets, and it is certainly a more extreme test of the optics than a smaller sensor, but if that concern can be mitigated or better optics used, it opens the door to the other important potential benefits of full-frame compared with APSc (or smaller), namely that:
- FF collects approximately 2.5 times more light than APSc and therefore should offer lower noise for an equalised field of view and
- FF tends to have greater well depth and hence greater dynamic range and is therefore likely to suffer less from loss of star colour for the same exposure
