"Have a heart and help a noob ." What I'm looking for: a sharp, wideangle lens for landscape photography. What I'm currently using: Tamron AF 11-18mm 4,5-5,6 Di II LD ASL SP // EOS 50D to be replaced by an EOS 5DII (no time soon though.) What I could spend: About $400. For some years now, I've been dreaming about shooting large panoramic landscape prints. I'm aware that the APS-C sensor of the 50D is not the best choice to do so, but as a mere hobby photographer my budget and wife do not allow me to obtain a better body. So far I've used the Tamron 11-18 on the 50D, mounted on a NodalNinja II and a Manfrotto Silver Jubilee tripod. Maybe there's a better, sharper lens out there I could get. What about a used "vintage" lens, as I see no need for autofocus here? Wouldn't $400 get me an older prime glass? Maybe my conceptions is all bs - what would you recommend please?
