I recently ran into an issue with my beloved Canon 35mm 1.4 L lens. After many years of exceptional quality and loyal service, it started to back focus when photographing an object or subject from that was more than 3 meters away.

Sigma's 35mm f/1.4 DG HSM is the first model in the company's 'Art' series of lenses. Designed primarily for cameras with 'full frame' (36 x 24 mm) sensors, it can also be used with APS-C sensors, where it covers a focal length equivalent to 56mm on Canon cameras or 52.5mm with other brands (Nikon,...

We're going to let you judge for yourself which lens is best for you. They're both excellent performers and can do a great job when used in conjunction with one another. But you're best off figuring out which focal length is better for you.

What a lens, everything the reviews say, brilliant, hope sigma keep coming up with stuff like this.

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.

-Great for Portraits -Great for Landscapes-Great for studio use/ small spaces-nothing to complain about on this lens! The bokeh is amazing! The autofocus works fast and great on the 5D3!

In late 2012, Sigma re-structured its lens lineup and announced that its future lenses would each be part of one of three new product lines: "Contemporary" for affordable consumer lenses, "Sport" for fast telephoto lenses, or "Art" for high-performance primes and zooms.

The Sigma 35mm f/1.4 is unlike any of the Sigma lenses we have seen in the past. I must applaud Sigma for stepping up and challenging the big brands, by spending their resources on engineering new generation lenses with amazing optics – all at a great value.

I bought this for my canon 6d and I couldn't be more satisfied with the pictures I've been producing with it. This is a great value and I've had a lot of fun shooting with it for the past few weeks.

Fast focusing; Looks great; Sharp; Strong build

Can't think of any

This lens is just a pleasure to shoot with, and gives your pictures a unique look that just makes you smile. I'm sure you've read a ton of other reviews that talk about its sharpness, and I'm telling you they weren't exaggerating.
