I've made reference to this piece of photo gear in a few comments on other photographers' posts, so I figured I'd just go ahead and write a review of a lens I recently had the pleasure of renting and using for a wedding.
The Sigma 30mm f/1.4 DC HSM Art Lens
I use Canon EOS gear, both crop and full-frame, and this lens was for the EF-S mount, which is the APS-C crop sensor bodies such as the 7D, 80D, and Digital Rebel series cameras.
Now, having said the above, since it's a Sigma and not a Canon brand EF-S lens, the mount still allows use of the lens on a full-frame body. Typically, however, using a lens made for a crop sensor on a full-frame body will create a hard vignette, like what you'd see on a circular fisheye lens, and which can be seen in this photo which I posted last week that was taken with a Canon EOS 6D and a Sigma 17-50mm f/2.8 crop lens.
Instead, the Sigma 30mm f/1.4 DC HSM Art Lens produces a great image which covers the entire swath of the full-frame sensor that is wide enough at its native 30mm focal length to use as a walk-around lens for capturing amazing candid moments. And, at the f1.4 setting it produces a wonderfully thin yet easily-manageable depth of field and attractive bokeh, as well as a natural and incredibly creamy vignette which can be toned down by raising the f-stop.
And not only is the focus fast, but boy is it sharp.
That was something I was really hoping would be the case for the Art series lenses by Sigma in general, and there's certainly no disappointment there.
Enjoy the sample images below! Some where shot at a friend's wedding, others were shot in my backyard to test it out around the house. Feel free to right-click any pic and view in a new tab to see them at a larger size.
