Need a wide-angle len that do not give too much of a distortion and yet able to capture landscape like Niagara Falls or Grand Canyon, etc.
Ideally, it can be used on SLR and DSLR.
If a len is particularly use for DSLR, how do I know if it can be used on SLR?
and how much vignetting the picture will turn out to be? Any formula?
Thank you.
