Is the Sigma 85mm F1.2 Art the new portrait champion for E and L mount?

Earlier this week, Sigma fully unveiled the 85mm F1.2 Art, a lens it announced would be coming earlier this year. We had the chance to shoot with it, and mainly focused on testing out its capabilities for portraiture, as that’s the traditional use for fast 85mm primes.

You can check out the sample gallery below to judge its performance for yourself. 

We found that shooting with it was the characteristically refined experience that we’ve come to expect from Sigma’s Art-series lenses. While a quality F1.2 lens will never be the smallest or lightest option, we appreciated that this particular lens is light for what it is; Sigma actually claims it’s the smallest and lightest full-frame 85mm F1.2 with autofocus for mirrorless cameras. It feels like something you could conceivably carry around all day without having to worry about waking up the next morning to an unusably sore arm (though I had it paired with an original Panasonic S1R, so it still made for a relatively hefty setup). 

The controls on the lens are also well-judged. I always appreciate a clicked aperture ring, though Sigma also lets you de-click it if you prefer. It’s also nice that you can lock it either into or out of the ‘A’ mode that hands over control of the aperture to the camera body.

While we haven’t put the lens through a full battery of tests to determine every aspect of its image quality, it’s hard to find much fault with the samples we’ve taken. It’s quite sharp across the frame, even at F1.2 (though obviously you’ll be working with razor-thin depth of field), though there’s definitely some chromatic aberration present. There’s also relatively strong vignetting at F1.2, which isn’t necessarily a surprise given the lens’s size, though it largely clears up by F2.8.

Whether you think the trade-offs of an F1.2 lens are worth it over an F1.4 or F1.8 will largely depend on your thirst for light and background blur. But before now, your options for this kind of lens on E and L-mount were limited to non-existent, so it’s nice that we’re getting a genuinely good option, especially one that comes in at just over half of what Nikon and Canon will charge you for a similarly-speced lens.
