Tokina 28-70mm f/2.8 AT-X 287 AF PRO SV
(From Tokina lens literature) The next generation of AT-X is the AT-X PRO SV series. The fist introduction is the AT-X 287 AF PRO SV, an exceptional 28-70 f/2.8 auto focus lens. With its emphasis on value, its cornerstone is it's heritage of Tokina HLD optical glass. Advancements in fabrication technology and the greater use of composite materials have created a lens that is lighter in weight yet more substantial value. The constant f/2.8 aperture makes focusing and shooting in low light situations much easier than other standard lens with smaller apertures. An internal focusing system couple to a Focus Clutch Mechanism yields quick and quiet auto focus as well as smoothly damped manual focus action.

8 out of 10 points and recommended by dugong5pm (52 reviews)feels like a pro lens, sharpnone for the price
I found it for $350 used. I think it was quite a bargain. This lens doesn't feel cheap at all. In fact, it's mostly made out of metal parts. IQ is good, very acceptable images wide open. I've got mine for the Sony alpha version, AF is ok, though might seems a lil bit noisy. I bought this lens to replace my 18-70 lenskit, and it's totally worth it.reviewed October 13th, 2012 (purchased for $350)

I bought this lens to go with my D50 becausereviewed November 17th, 2006 (purchased for $340)
a) I wanted a fast full frame zoom that could also be used with my FM2n s
b) It was cheap enough
The image quality has been better on the D50 than I expected. It can be a bit soft wide open, but then so if you want to be critical can an AIS 50mm f1.4. The built quality feels excellent though I've not dropped it to test.
