A 18mm prime on APS-C? Why? You are better off just using a 18-55mm VR kitlens, to be frank.

If you were talking about a D700 instead, it would make sense.

Just look at an UWA zoom for APS-C. Either the Tokina 12-24mm f4 DX, or the Sigma 10-20mm f4-5.6 DC. Or if you have a bit more money to spend, either the Tokina 11-16mm f2.8 DX or the Sigma 8-16mm DC.

That makes sense if one needs wider than 18mm (27mm). Personally I think 18mm is wide enough for many applications, but probably yes, for architectural one may want wider.

The other thing is, I was also keeping my eye on 20mm 3.5's and similar, for a while. They go for quite a lot used, > 250. With the coming of the Nikon 18-35 new one, and the Sigma 18-35 1.8 for DX, at the prices < 800, and their 'reported' optical quality by the many reviews (albeit real life everyday  photos still to be seen across the board like on pbase and flickr) I would surmise that the recent additions are now fair comparison and better value, considering.

So, I suspect that the prices of the older wides are going to take a big hit, especially for aps-c users who can get the new Sigma which has rave reviews and is 1.8 constant.

And as you see the postings on  these board, the 18-35 Nikon is just as fast basically as the older f4 lenses, with great optical quality, for FF.

I think the older wides are about to take a dip on the used markets. Their attraction was prime quality at a low'ish' price.

But the two new zooms seem to compete very well. I was really not intending to get an APS-C only lens, but the new Sigma looks very interesting.
