Lens Comparison | Sigma 24-70mm f/2.8 Art VS Canon 24-70mm f/2.8L II

By Holly Roa on December 18th 2017

The 24-70mm lens has long been a staple in many a professional photographer’s kit, and if you are in the market for a fast, sharp, fixed-aperture zoom, chances are you’ve been poring over tech specs and 100% crops of some of the biggest contenders in this category.

Hands-on comparisons are preferable to the obsessive googling and pixel-peeping to which many photographers are prone when on the hunt for new glass, but it’s not always practical to rent or borrow what you’d like to buy.

Bridging the gap between reality and the still image, though, is the next best thing to getting the gear into your own hands – YouTube. Ireland-based photographer and vlogger Anita Sadowska has pitted two of the top 24-70mm f/2.8 choices for Canon shooters against one another for your comparing pleasure in a recent video; Sigma’s 24-70mm f/2.8 Art lens goes head to head with one of Canon’s finest offerings, their own 24-70mm f/2.8L II.

Sigma’s Art series has made a name for itself as a competitor to first party lenses in every focal length they’ve introduced, and Canon’s 24-70mm f/2.8L II is known to be one of the sharpest and best in its class. In the video, Anita tests some important issues, including one that has been hanging like a raincloud over Sigma’s head as user experiences rattle around photography communities – autofocus.

      I would get the 24-70 mark 2 for portrait if i had the cash, it can get me through the whole day in a wedding event, having the 24-70 gives you tons of option unlike the 85 which leaves you stuck in 1 particular focal length.

    Autofocus reliability/consistency = I’d pick the Canon all day.  Even with the Sigma USB dock, the Sigma has a considerably higher AF miss rate than the Canon from the testing I’ve seen.

    Enthusiasts should also give the canon 24-70 f/4L IS a good look if you aren’t shooting portraiture or sports with it.  It’s a perfect hiking / walkabout / travel lens as it’s much lighter, stabilized, sealed, quick focusing and sports a 0.7x (1:1.4) macro option.

      F/4 is my go-to lens aperture, the minute I’m not shooting portraiture or action. So much lighter, and most f/4 zooms are just as sharp if not sharper than their f/2.8 counterparts, even when stopped down. The Canon 70-200 f/4 L IS and 24-70 f/4 L IS, and/or the 16-35 f/4 L IS, make one of the most awesome travel kits that a DSLR owner can want, in fact all three of those lenses are roughly the same size and weight as the competing Sony f/4 zoom trio. Go figure!
