So I'm planning on getting the 7-14mm and considering the 14mm f2.5 Just curious if anyone has done a comparison of lenses at 14mm.. say the 7-14, 14-45, and 14mm f2.5? I guess my real question is if I'm planning on getting the 7-14, would the 14mm f2.5 be worth it? I can definitely see myself shooting at this focal length a lot. The faster lens would be a plus but if the 7-14 is just as good (or better)... I might could live without it. If anyone has both lenses please chime in. Any input is greatly appreciated. Thanks.
