Now I certainly Tokina AT-X 12-24mm F4 PRO DX (not II) but as I understand it, is it just that this has built in AF motor in the lens, something only Nikon owners get pleasure from and that the lens has a new coating on the front lens to prevent lens artifacts. There should also be a red line on the version II.
Well, since my camera bag gaped up at wide-angle lens so I decided to turn to the Tokina 12-24mm which I had read about before. Can say that I am satisfied with my purchase and it fits very comfortably on my Canon 50d.
The first thing you notice is how heavy and solid it feels. It may thus seem a little forward heavy on a Canon xxxd / xxxxd camera.
Autofocus is good and in my opinion quiet. To switch between auto / manual moves front and back focus ring. Think it works fine, but avoid making it too often as it rips on it.
F4 can feel a little faint (often use the lens in confined indoor environments) but it's great to have F4 along the entire range at least. The lens feels sharp along the entire range but a little soft at 24mm, but I use it almost never.
The only major problem I have with this lens is the amount of CA (chromatic aberration) as it forms, especially at 12mm @ F4. I get it off without much worry on the computer, but I've never seen so much CA from a lens before.
