Sigma 12-24mm F4.5-5.6 DG HSM II Lens Review by Thann Clark

Sigma 12-24mm Lens Review photo by Thann ClarkI am picky when it comes to wide-angle lenses, I’m not a big fan of fish-eye, or ultra-wide lenses, there is usually too much distortion for me. So I was surprised how much I liked the 12-24mm lens from Sigma. It is a rectilinear lens, so the distortion is minimal. Bottom Line – this is a very cool lens, that is fun to work with. There are a lot of creative possibilities packed into this sleek looking lens.

I was focusing on objects just 5 inches away. Even that close, the wide field I was able to capture did not seem physically possible. The lens has an angle of view from 84.1° – 122°.

This quality makes it a great lens to use when you have to shoot wide and have little room to move back. If you have to shoot large group portraits, this lens is an excellent choice as well. You will not have to keep shouting at grandma Phyllis to get closer to uncle Jack, “C’mon act like you all like each other.”

It gives images an inherent feel of motion, and is interesting to see. Like all wide-angle lenses, distances between objects are visually increased, which is great if you want to exaggerate elements of your image and play with size relationships.

The technical guys will talk of optics, and the 17 elements that make everything happen in a scientific way. But to be able to get so close to the subject, capture such a wide field, and get an image that is so undistorted has to be magic.

Sigma 12-24mm Lens Review photo by Thann ClarkIf you are looking to add a rectilinear wide-angle lens to your bag, you owe it to yourself to look into this lens (literally and figuratively). It will inspire you to capture creative images, and is really useful for group shots, landscape and architecture.The only draw back to shooting with this lens for me is I have to give it back. 

The Sigma 12-24mm F4.5-5.6 DG HSM II Lens works with full frame DSLRs but will also work with APS-C cameras. Available in mounts for Canon, Nikon and Sony/Minolta.
