The Sony 12-24mm f/4 breaks a bit of new ground as an extreme ultra-wide angle zoom lens. It’s a remarkably compact lens for a 12-24mm full-frame lens, and the construction is solid without making the lens too heavy. The 12-24mm produces images with very good image sharpness across most of the frame throughout the zoom range, and has surprisingly good CA control and excellent color and contrast.
The usual compromises for extreme ultra-wide lenses are here as well, with fairly hefty distortion and strong vignetting. However, the overall image quality is very good. When you consider the small size and extreme focal range, it’s a really impressive lens. While the 12-24mm is definitely a bit expensive, at $1,700, it also isn’t out of line with competing lenses from other manufacturers. If you need a zoom in this focal range, is easy to recommend.
