I've been a working photographer for over 30 years, and never owned a Sigma lens before. For years I shot weddings/events/meetings with Mamiya/Pentax (medium format), and gradually moved to Canon/Nikon in the digital years. During that timeframe, I only purchased and used OEM lenses.

I bought the Sigma 24-105 Art to use with my 5D Mark II based on many stellar reviews. So, when I got it I immediately did test shots (comparing to my EF 28-135) and discovered that generally the images were not up to the quality of my Canon EF 28-135 with the exception of contrast.

Strong Construction

Blurry Focus; Heavy

Solid build and a great looking lens. The SLR Gear review is right on. Though this Sigma is large and on the heavy side, for what its giving, I'll gladly haul it around. I first tried the Tamron 24-70, another great performer optically, more expensive, but also rather heavy and more limited zoom...

Excellent all around performer; sharp; good contrast; very pleasing build

weight; not weather sealed

SUPER SHARP. Using on a D7100 and D500. Perfect focal range for family photos, portraits, groups, etc. Great "walk around" focal length. LOVE this lens. Very solidly built like the other ART lenses. It's heavy, just shy of 2 pounds. Smooth stiff zoom ring, doesn't float. Really fine quality optics.
