TPF Noob!
First, two facts:
a) Shorter lenses distort the image, giving it the wide angle feel. It usually gets noticable at 24mm and below.
b) On a small sensor camera, it takes a crop out of the larger availible image.
So using this logic, even though a 30mm lens will give the standard view (like a 50mm on a full-frame sensor), it will have some image distortion. As I use smaller and smaller lenses, it should get worse. Is this correct?
And lastly, if I were trying to get a full-frame equivalent of 28mm, I would need to use an 18mm lens. This is usually down in fisheye range, with incredible perspective change. Do wide-angle digital specific lenses correct for this fisheye distortion?
As always, thanks!
