Sigma 10-18mm f/2.8 DC DN Contemporary Reviews

Perfect lens for Canon APS-C mirrorless

By Jeff
Rated 5 out of 5
Date: 2026-05-31

I used Sigma lenses on my Canon 60D for many years, along with Tamron and Canon lenses, and always had a soft spot for Sigma as they are extremely well built and well designed. This lens is possibly my top choice for the Canon R10. Over the years I have moved from event photography to landscapes, and this tiny lens is so fantastic for travel that the Canon equivalent is not even in the same league. It weighs almost nothing, features a constant f/2.8 aperture, and provides wonderfully consistent colors with very little aberration, all of which is easily fixed in post. It is very cheap for what it is.

Maximum fun lens

Ultra Wide angle, high level of fun lens. Great for shooting photos at parties, car shows, and parked aircraft at Air shows and such. Landscapes and great close-ups too. Buy it. You will be happy you have a camera to put it on. Sony a6700.

Will this lens work with the Canon 7D, Mk II?
Asked by: Jerry
A lens made for a mirrorless camera system like the RF mount would not fit or work with a Canon EOS 7D Mark II DSLR Camera. For a Canon EOS 7D Mark II DSLR Camera, you would need to use an EF or EF-s lens.
