سلام جناب farhad44
این کار باعث میشود ترسم از انتخاب بدنه های غیر فول فریم بریزد.
اینم واسه اینکه بدونی کراپ دار ها میتونن از فول فریم برتر هم باشن آقا ضیاالدین!
یک موردش:
Some photographers say that this extra reach amounts to a crop of the full frame—equivalent to simply blowing up the center portion of the full-frame image.
But this is a film analogy that doesn’t hold true in the digital world. The APS-C camera concentrates all its pixels in that smaller frame, whereas if you crop the image from a full-frame camera, you lose pixels.
For example, if you put a 200mm lens on a 12.1MP full-frame Nikon D3, then cropped the picture to a field of view equivalent to what you’d get using a 300mm lens, your image would wind up just 5MP in size. But if you put the same lens on a 12.3MP APS-C sized Nikon D300, you’d get a 300mm-equivalent image—with the full 12.3 megapixels.
With today’s high-resolution full-framers, that compromise isn’t as striking, but it doesn’t disappear. Put a 200mm lens on a 24.6MP full-frame Sony Alpha 900, then crop, and you’d get a 10.5MP image—respectable, but still less than you’d get with a 12.2MP APS-C Sony Alpha 700.
So the telephoto advantage of smaller-format DSLRs is very real. Sports and wildlife shooters in particular can benefit from a smaller-sensor DSLR, either by getting long reach with relatively compact lenses, or by getting huge reach with big “legacy” glass—full-frame lenses originally developed for film SLRs
