Review Date: May 19, 2008 Recommend? yes | Price paid: Not Indicated | Rating: 8 

 
Pros: ultra sharp, fully correctable CA, very low distortion
Cons:
dust sucker, size, doesn't fit my Nodal Ninja 3

I use this lens as my main lens. I mainly shoot architecture where I use it at 17mm.

I love this lens for it's superb sharpness even in the corners. If you need a standard zoom I think there is no better alternative.

At 17mm there is some colour aberration. But when you shoot RAW and apply a correction of -25 in Adobe Camera Raw you won't see any left. Contre jour performance is good too. Both the Tokina 12-24 and the TS-E 24 have worse performance regarding CA.

After two years now you see dust particles behind the front lens. However I couldn't find an influence on image quality probably because the front lens is very big. I assume the dust enters where the zoom moves in and out.

It would be a good lens for making panoramics. Therefore it's sad this lens doesn't fit Nodal Ninja 3 because the nodal point is too far away from the sensor. Have fun with Nodal Ninja 5 or any bigger nodal adapter.

Pros: build quality
Cons:
sensitive to blooming

I usually shoot architecture with my EF-S 17-55 and I needed a wider lens. So I got the Tokina 12-24. Those extra 5 mm make a huge difference!

It is very sturdy and the handles are extra smooth.

You will wish to correct the CA during raw processing. Normal CA can almost perfectly be corrected. However on high contrast edges like a white facade against the sky you'll note a slight halo.

The lens is also very sensitive to scattered light. Keep direct sunlight away from the front lens! On the other hand I don't think it's worse than other 12 mm lenses.
