Tokina http://www.amazon.com/exec/obidos/ASIN/B00099C2M6/kenrockwellcom Nikkor http://www.amazon.com/Nikon-14-24mm...1?ie=UTF8&s=electronics&qid=1204109236&sr=1-1 The last piece I feel I need, for the moment, is a good wide-angle lens. Man, though: At an over 1k price difference, the Tokina is... extremely tempting. Extremely. Can anyone justify the price difference between the two, or even the 2x price difference between the Nikkon 12-24 f/4 and the Tokina? I mean, the first I can understand the price discrepancy (just not the degree) but the latter I'm baffled.
