Overall, not a bad thing can be said about Sigma ‘ s 35mm f1.4 EX. The company surely put a lot of time and effort into the design and it ‘ s worth every penny. The lens is sharp as a razor, a relative speed-demon when it comes to focusing, and has some beautiful image quality.

Cost of Sigma lens vs; cost of Canon, Nikon or Zeiss lens, Great image quality, Optional USB dock to update firmware, Fast autofocus speed

Lack of weather sealing

I try from a friend mine. It is a super lens, excellent quality. Not just sharpness as smooth for a profissional classic photographs. Great Great lens, help the good photographers, profissional or not. Superb!!!...

I bought this to shoot weddings - it takes a bit to get adjusted from the versatility of a 24-70 but once you do you don't want to change lens even when you know / you're taught in some cases you should be using a longer lens! At F/2.8 it's almost TOO sharp! But vignetting is heavy wider than f/2...

I was always told, 'You get what you pay for' and this lens is no exception! I've used the lens at f2.8, 4 and 8 and could not tell the difference in picture quality or sharpness across all apertures. Ok, so the lens is a bit bulky, but that's because it contains a serious amount of glass!

I always regarded Sigma as being a cheaper third party lens. This lens is quite possibly the best prime lens I own. I have several brand name high end prime lenses that perform well but nowhere near as superb as this.

This is a very good prime lens for portrait, street shooting, and some landscape. Works fine on my Nikon D700, but need to adjust focusing with +15 fine tuning, not bad at all! Image quality is super good, someone said it is even better than 35G, which is $500 more expensive than this one!

Great product, I recommend those who want best in class image quality to get this lenses. I needed to shoot indoor all the time, 35mm is perfect wide angle for indoor use and large apature helps with low light condition. What'd wonderful glass.

Build quality

Bulky

very sharp lens. Great for walk around and street photography. Sharpness intact even after cropping. great capture in low light because of the f 1.4. Feels great to hold and premium finish. Paired with my Nikon D750 it works just great.

This is an amazing lens. So sharp even at 1.4. Solidly built. I'm have a nikon d610 full frame and the rest of my lenses are nikon and this is far superior in imaging quality and build

Fantastic quality lens, big and heavy, but worth the extra weight. Its super sharp, fast autofocus, wide maximum aperture for low light, and great bokeh, and solidly build. The Sigma 35mm Art is equal, if not better than the Canon L series 35mm, and is now my main wedding lens.
