Morning :) Well I'm looking to get a wide angle lens for my Nikon. It has a crop factor of 1.5 so I need a shorter focal length than usual... I have a 35mm prime lens that behaves more like a 50mm because of the crop factor. But I'm wondering how the crop factor effects distortion, if it does at all
Would a 10mm lens, for example have the distortion of a 10mm lens on a cam with crop factor, or would it have the distortion of a 15mm lens? I'm a little braindead in this area!
As I need to get a shorter focal length to get a wide angle field of view on a cropped sensor, I'm wondering will it suffer from more distortion than usual, or will it just behave like a longer wide angle lens on a full sensor camera
@johnp It all depends on the particular lens in question. In general terms, a rectilinear lens will exhibit less distortion than a fisheye lens. A 10mm rectilinear lens on a 1.5X crop body should look about the same as a 15mm lens on the FF camera. But in practice no two designs are identical and either lens could be better corrected than the other.
