If, like me, you're accustomed to edge-to-edge sharpness and couldn't bring yourself to even press the shutter-button, with the expectation of chromatic aberration, with it's purple-fringes, then this lens is for you.

For its type, the Sigma 12-24mm f/4 DG HSM Art lens is a good performer and buyers should be satisfied with the results they can obtain with it, provided they are aware of its capabilities and limitations. It's also a lot of fun to use.

Noticeable vignetting at the maximum relative aperture on full frame.

It’s easy to look at the price of expensive lenses such as the Sigma 500mm f/4 DG OS HSM Sport and immediately disregard them from your radar. While the price implies working pros specialising in sports and wildlife are the only ones ever likely to purchase such a lens, it’s possible to get it in...

This is a brand new lens in the Sigma line-up and dPS had a chance to try it out. See...
