|comment:||I like this lens - I use it with APS-C and also with FF. |
The 12-24 delivers good image quality with 122°. The colour
reproduction is very natural and pictures with the 12-24 show a distinguished colour palette that invites you to step into the picture and marvel at the quality of reproduction and the depth of perspective.
The lens is sharp enough at f4,5-f5,6 in the center, but not the borders and corners! You have to stop down to f8 for good and f11 for corner to corner sharpness on APS-C. My point of view is that you need f14 for optimal sharpness on the FF Chip. I see minor limits of defraction at f11 to f16.
I often use this lens for architecture and landscape shots.
With f14 you have the hyperfocal DOF. You need experience to take shots when the sun is in the "field" - the lens catch flare very easely. Sometimes you can block the sun with your hands.
The distortion control is excellent for a zoom lens.
The mechanical quality is good: the mechanism of internal
focusing is indeed incredibly smooth in its movement.
The 12-24 is a very fine tool for the photographer
who wants to create pictures with a very strong visual
impact and a wide dimensional scope.
Recommend for Full Frame and APS-C users
if you can find a good sample.
