Does my crop sensor camera actually turn my lenses into a longer focal length?
My wife has a pair of Tokina lens (28-80mm and 100-300mm, I believe, without the lens here to check) from her old Minolta film SLR that we've been using with Sony DSLRs. I was told that these aren't actually those measurements for a DSLR, but to multiply by 1.5 because of the cropped DSLR sensors. That would mean these two lenses are effectively the same as a 42-120mm and a 150-450mm (!) lens if we bought equivalent Sony DSLR lenses. Is that correct?
It seems too good to be true in the larger lens' case, so I'm looking for the catch.
