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

Quite heavy; Expensive; Omits optical stabilization; May require focus adjustment

Long ignored by Canon and Nikon, Sigma proves it has what it takes to revitalize the 135mm portrait lens.

Very sharp; even at f/1.8; Beautiful bokeh; Fast; accurate autofocus; Weather-sealed mount; Three-position focus limiter

Big; heavy; No image stabilization

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.

Sigma brings us their latest Art lens, intended to represent the pinnacle of the lens makers' art, a super bright 135mm f/1.8. This is one of the most popular traditional focal lengths for full frame cameras, ideal for a wide range of subjects and particularly portraiture.

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.

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.

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...

Superb sharpness and very few optical aberrations; Dreamy bokeh; Superbly built

Rather hefty

Sigma is currently having a run. Unlike CaNikon, who seem to have slowed down their activities lately, they are providing a continuous stream of highly interesting new lens designs and not only that - they are pushing their product quality to a level that is now truly threatening the original...

A+!
