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.

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...

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 F1.8 DG HSM Art is very sharp, focuses quickly, is built tough, and gathers a heck of a lot of light at f/1.8-which, combined with the long focal length, nets shots with extremely blurred backgrounds.

Razor sharp; Wide aperture; No distortion; Minimal falloff; Dust- and splash-proof design; Focus limiter switch; Available for Canon, Nikon, and Sigma systems

Since the inception of its premium Art range of lenses towards the end of 2012, Sigma has gone from strength to strength. The 35mm f/1.4 DG HSM Art lens that kicked the whole series off has since been joined by four more focal lengths – 20mm, 24mm, 50mm and 85mm – to fill out an impressive set of...

Rather hefty, Rather hefty

A+!

I bought this lens through Amazon. It was delivered directly from Japan, and delivery was quick. I shoot on a D610. My original pictures were a bit lackluster but didn't have any focussing problems.

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.

Durable; Great Picture Quality; Simple Controls

Bulky

First... wow, what a beast! This is a seriously massive and heavy lens. The size, heft and operation of this lens just oozes quality. Photographers struggling with weight issues are strongly encourage to find an 1130 gram weight (39.87 ounces) to get an idea about how massive this lens is.

Sigma's range of Art lenses has catapulted the company into the upper echelons of lens production, and the 135mm f/1.8 demonstrates the appeal of the series beautifully.
