Too funny, so is an actual focal length, of a 300mm lens the field of view shot on a 645, an FF an APC-s a 4/3 or a Q?
Trick question...
There is no actual focal length. A 300mm lens is still 300mm, no matter what format you shoot it on. Only the field of view changes, Since the largest format you could possibly use a 300mm lens on would be an 8x10 view camera, all those digital formats are horribly cropped. The term cropped sensor was designed by camera makers that make FF cameras, to sell cameras to fools. Of which there are plenty.
Even in digital a 36x24 is a cropped sensor. SO you're saying the uncropped FoV would be 300mm on a 645 camera? Ya, I'm with you, I'd love a 300mm lens on a 645 D or Z too.
