Yup, Im back with another question lol. Only cuz this site is soo helpful. Anyways, Im in need of some guidance on a wide angle lens for landscapes/cityscapes. My first question is, what are some options that I have for the Nikon F mount (besides brands like Sigma, Tamron, Nikon and Tokina)? I would like to find a lens that will still allow AF on my D5000, but I dunno that it will happen. Next, would the benifits of a prime lens outweigh the versatility of a zoom lens? If so, considering Im after AF, wouldnt that pretty much limit me to Nikon lenses? Again, the only brands I know are listed above. I cant seem to think of any other questions right this second, but Im sure theyll pop up. Thanks.
