Eye autofocus works even in the worst light with this lens. It is tack sharp wide open at f1.8 and requires no stopping down to guarantee focus even in terrible conditions. The resolution is easily good enough for the 42 megapixel sensor.

In our review of the Sigma 85mm f/1.4 HSM DG ART we were pretty much stunned by its quality. However, the Sigma 135mm f/1.8 HSM DG ART tops that. Those who have followed us over the years know that we don't easily come up with superlatives but this time it's hard to avoid them really.

The Sigma 135mm ƒ/1.8 DG HSM "Art" is one of the sharpest lenses we've ever tested. It's not an inexpensive lens, but for what you get -- great build quality, outstanding sharpness, little to no chromatic aberration, and almost zero distortion -- the lens is worth every penny, and destined to become...

This lens is everything reviewers say. The lack of VR/IS is a non issue with my Sony A7R3, while the extra 1/3 of a stop over my previous Nikkor 135 F2 DC is always handy. The Bokeh is the equal of the legendary Nikkor but much easier to use.
