I'm thinking of buying a secondhand Nikon 12-24mm f4 and wanted your thoughts. There's plenty of other lenses available from Sigma, Tamron and Tokina, should I be considering these? or maybe the newer Nikon 10-24mm?
14 - 24 is where the party's at!
For Nikon I found the Tokina 11-16 the best UWA although there's not a lot in it compared to the 12-24 and there's always PS anyway. The Tokina is more flexible- lack of range I always thought was a mute point seeing as most UWA's are nearly always used at their widest and that's where a lens collection comes in though I appreciate it could be handy.
