Searched and not many have used this lens, should I assume it is not a good lens? I am thinking about getting it as it almost perfectly fits my needs. I was about to pick up the 11-16 f2.8 when I came across this lens. It is $50 cheaper and provides a focal length that I think will be almost universal for me to use. However, my main purpose in getting a wide angle lens is to take great landscape shots, will I be disappointed with this lens? I know the 11-16 is super wide and I will probably be very happy with it, but I am trying to kill two birds with one stone. The 16-50 will provide a wide angle (but will it be wide enough?) for landscapes and the 2.8 and the zoom will allow me to use it for indoor pictures. Advice? Tips? Recommendation? Will be shooting with a Canon T1i.
