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.

The Sigma 135mm Æ’/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...

In this quick review of the Sigma 135mm f1.8 Art Lens, I will go over some of its features and...

In comparison, it’s a different lens from the Sigma 85mm f1.4 Art lens but probably not enough besides focal lengths.

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.

I'm a wedding photographer and purchased this to replace my Zeiss 135mm/2.8. I loved that lens, and I love the Sigma 135 even more. The extra f-stop is clutch for lower light ceremony situations, and the compression is great. Focus is sharp and fast.

I’ve had my Sigma 135mm for about 6 months now, so here are some thoughts: The aperture capabilities are wonderful and the color even from RAW photographs are undeniably beautiful. Such awesome bokeh, and I found out that it picks up lasers (like what you’d find on a dance floor) really well.

As a pro event and wedding photographer Ive shot over 480,000 images on my D3s alone. I recently purchased this lens after weeks of research for my new D850. So far Ive only used the D850 with my Nikon 70-200 f/2.8 VR II lens and just couldnt understand why the image quality didnt blow me out of the...

This lens is just amazing. I have never had the urge to write a review about a lens but this lens needs to be respected for the quality it brings to the photos.I have always stuck to my Nikon lens and never considered going third party. But Sigma's Art lens is top of the line and I have no regrets.

I have only been able to take it out a few times; once with A7rii & twice with A7Riii, but so far loving it. Although it is a bit heavy, it wasn't unexpected. Very sharp wide open, fast focusing and love the bokeh.

I want to share my experience with this lens. I had owned several other Sigma lenses and found them all optically excellent but had some sort of autofocus issue or another but the 135 is stellar. Performs like some of the Nikon lenses I have used.

I have owned the canon version with the MC11 and it was nice but the E Mount is awesome. Extremely close to the operation of my 85mm G master. Focus is FAST, no hunting and its SHARP wide open and edge to edge at 5.6 and 8..

This lens is F'ing SHARP! I own the Sigma 35 f1.4 art and the Tamron 85mm f1.8 and this lens is sharper than them both wide open! I honestly didn't think that ANY lens could be VERY much sharper wide open than the Tamron, but Man, this lens is!

I used nikon 85 1.4g, nikon 105 1.4, nikon 135dc, Sony 85 1.4gm for a period of time before, all are wonderful ....but believe me, this Sigma 135 Art is simply stand out from all of it, unbelievable sharp at wide open, smooth and wonderful bokeh (no cat eye, only sony 85 gm with 11blades can...

This lens is tack sharp. The focus is fast and accurate (when using the switchable focus ranges it's very fast and accurate). I've been using this lens for over a month and it rarely leaves my camera.
