I have multiple canon lenses most with L rating. Depending on usage this sigma art lens blows them all away. A few months ago I took the photographs for my daughters wedding using only this lens on full frame camera. Excellent results. It stays on one of my cameras all the time now.

"I mainly use my Canon mount lenses for wedding videography but I'm a photography enthusiast as well. This lens produces gorgeous video and photographs paired with a 5D Mark iii. I have a lot of glass, including Canon L glass, but I keep reaching for this lens the most often.

Had two bad copies so far, both inconsistent focusing especially at apertures from F1.4 to F2.8. Using a high quality, sturdy tripod, taking photos of the exact same thing will result in front focus in one, back focus in the next, and maybe one (or two if I'm really lucky) sharp one out of 5...

BUY IT NOW, save yourself from the Canon 50mm lineup and get even somewhat better quality than the prestigious 50mm "L" lens... Canon's is good/great, but after some review this one has the upper hand in 50mm (only this range, "L" is preferred on all others for me)... can't wait for the 5D MK2...

Inexpensive; sharp at 1.4; and great background blur; blows away my former Tam** SP F2.8 lens; ultra fast focusing on my 50D; a great pair for portraits; made my photo shoot go easy the other day and it made it hard to pick which photos to use; THE WERE ALL GREAT!!

its not a 1.2; ummm

50mm is the focal length most used by doyens like Ansel Adams . This lens justifies it's position for being among the sharpest 50mm ever produced. It's sheer poetry to play with this piece of art. Just wished Sigma started developing weather sealing to it's Art armoury.

Excellent tool for three quarter and full length studio shooting, and most work,this is the lens of first choice for day to day shooting both inside and outside. The quality when attached to a full frame FX body is quite unbelievably good,It has been said that this lens is bulky however to achieve...

One word for the product: AWESOME Let me list out the pros and cons below for better readability. I am so excited about this product that my words will just mix-up. PROS: 1. SUUUUUPERIOR quality images. DAYUMMMN sharp.

The Sigma 50mm F1.4 DG HSM is a fast and tack-sharp lens, both in the centre and at the edges of the frame, with virutally no evidence of chromatic aberrations and very little distortion.

Another fantastic performer. Sigma has been getting serious for some years now, and each and every Art series lens I have bought I have been most impressed with. Some years ago I told myself that I would never sell this or that genuine Canon L series lens in my extensive collection.

One of the nicest things about Sigma lenses is that they come with a padded pouch, instantly suggesting that the manufacturer feels the lens is worth protecting. Sigma's 50mm f/1.4 is no exception, boasting an enormous front element and a .
