I don't specifically interested about any brand, but I love Canon, Nikon and Sony. Can we use full-frame lenses for Canon, Sony and Nikon APS-C cameras? And I would like to know what is the difference between Canon USM and TSM lenses.
I saw in some articles that Canon has 1.6X crop factor compared to 1.5X in Sony and Nikon. Does it significantly affect the picture quality or photography? Should I worry about it.
Thanks.
Added (1). Recommend me some good cameras much as you can around that price category. Please mention the which camera you mostly prefer among them and why.
