I currently own a Nikon D5200 DSLR with stock 18-55mm & a 50mm prime lens. I'm in need of wide angle telephoto lens. I've searched a lot in the internet and read a lot reviews of various lenses. Atlast i came up with these, Tokina AT-X 116 PRO DX AF 11 - 16 mm f/2.8, Tamron SP AF 10 - 24 mm F/3.5-4.5 Di-II LD & Sigma 10-20mm f/3.5 EX DC HSM, etc. So please help me chose the right wide angle lens witha little bit more zoom and nice picture quality. Lenses apart from above listed can also be considered according to ur suggestions. Thank You.
