I am doing a two stage upgrade from a d5000 with an 18-200 lens to a d5200 with an 18-300 lens. About a month and a half ago I bought the 18-300 lens and it seemed to be sharper than my 18-200. Then last week I got a d5200 and my shots all seem to be just a bit softer. I've also noticed on the metadata that the 35 mm equivalent is the same as the focal length, rather than the 50% increase it should be (i.e. at 300mm on the d5000 the 35mm equivalent was 450mm while on the d5200 300=300).
Any thoughts? Are the two (softness and 35 mm equivalence) related?
