Design & Features
The Tokina 12-24mm f/4 ATX Pro DX is a ultra wide lens specifically designed specifically for Canon and Nikon APS-C format DSLR cameras. The lens has a constant maximum aperture of f/4 throughout the zoom lens with the optical construction made of 13 elements in 11 groups with diagonal angle of view at 99 degrees. This lens gives its users a super wide-angle zoom lens which has the equivalent of an 18-36mm zoom range on a 35mm film camera.

Compared to the Sigma 10-22 (470g), Tamron 11-18 (375g) and Canon 10-22(470g), this lens is hefty weighing in at 570g. I must admit that the build quality is excellent and if you shoot with Nikon you’re just going to love this lens more as the lens has a black crackle-coat finish similar to some Nikkors.
The lens has a filter size of 77mm and has no manual/autofocus switch. You can change the manual/auto focus by moving the focusing ring back and forth which I also like.
How does it perform?
This is the best part. The lens is about $500 cheaper than the Nikon 10-24mm but the build and image quality is fairly up there. It gives you good sharpness (even at the corners), colors and contrast at all apertures and focal lengths specially when stopped down to f/8 or f/11. I see some vignetting issues only at 12mm at f/4 but you can always stopping down to 5.6 and further to reduce it. What about flare? Yes there is some flare, but hey.. it’s a ultra wide zoom lens after all. The provided lens hood will help you a bit but I saw fringing in the corners at the 12mm.
There is a very little amount of distortion throughout the zoom range. I bet you won’t notice it unless you use the lens for shooting brick walls.
I love the autofocus which is fast and precise on outdoors. When use it on indoors with less light condition the lens was also able to focus quite fast. Experiencing a little bit focusing problem on some low contrast objects but nothing to worry about.
Should I buy it?
The answer is easy with this one; YES.
This lens offers solid build quality and stellar performance and for the price I’m not sure it can beat by anything else in this class. So if you are looking for an ultra wide zoom I would highly recommend the Tokina 12-24mm f/4 ATX Pro DX.
