Officially it’s “AT-X 124 AF PRO DX”. Their first shot at a crop-factor DSLR lens, and quite a big success; lots of people on the net like it for example.
A previous round of test shots when I first got this lens is here.
And why am I testing this when I’m leaving DX and about to sell it? Well, I needed to test my old 28-70, and I decided I should include other lenses as sanity-checks, so I’m looking at more than one set of results.
12mm f/4
So not so shabby really, I don’t think.
12mm f/8
There really isn’t anything much wrong with this by f/8.
24mm f/4
The 24mm end is pretty fuzzy in the corner too, at f/4.
24mm f/8
Pretty nice, especially in the center. Possibly better than the Nikkor at f/5.6, even.
