And I am surprised that the new Sigma 50/1.4 Art is even sharper, with more contrast.

The Sigma improves on all of these things, a tremendous amount

But in this case, my older glass outperformed the Sigma

I was told by the salesman at the shop that the Sigma was superior in sharpness to the newest Nikon 50mm lenses (of a similar price), in that the latter had chromatic aberration problems

After all of my troubles I swore off Sigma and bought the Canon 35mm 1.4, and I love that lens, I only regret is having to pay the Canon Tax of $300-400 for a lens that is optically just short of the Sigma's excellence, but it focused accurately and that is very important for paid assignments

Also, the Sigma 50's bokeh while much smoother than the Sigma 35, lacks the silky quality of the Canon's primes...particularly the Canon 85 1.2 and 50 1.2 (which I owned for a while).

Sigma has outdone themselves and about everyone else in the industry with this remarkable lens.

Its heavy because of all that great Sigma glass

After shooting with this for a couple of days and letting the initial elation with how sharp the lens is wear down, I started to notice that much like the Sigma 35, the Sigma 50 seems to lack the tonal depth and richness of Canon's L primes....particularly in rendering the subtle gradient shifts on skin tones exposed with a soft light.

Well done Sigma

Hopefully Sigma can improve it's quality control and double check for poor lenses leaving the factory

Sigma is really scary with their lens designs, because they're really pushing the envelope

Well, overall, Sigma created a knockout lens

Sigma has another winner on it's hand that can go toe to toe with the best of Canon.

If weight is a concern, just buy the Canon 50mm f/1.4.Compared with the Canon f/1.2, the Sigma is sharper, no doubt

We all want our pics to be as sharp as possible and Sigma, by margins, is sharper

Nifty Fifty’ Sigma must have thought of ‘Chunky Monkey?’2

Well, Sigma is at it again, the new 50mm Art is another lens winning praise on every review site, but because of my previous experience with Nikon D800 and Sigma 35mm, I have trouble trusting these reviewers.

Great work, Sigma!Some people don't like the different filter thread size on this guy compared to what they're used to in a 50, or the weight, but it doesn't bother me

Simply superb, these Sigma Art

DID I MENTION, SHARP?Seriously, I've had the 35mm version of this lens for a while and felt like comparing the Sigma 50 to my Canon 50 f/1.4, guess which one is getting

Either way, this Sigma is pretty damn good

Sigma is like enigma when the fall in some sort of pricey category lens and if I can say, it's worth the effort timing to advance in such engaging glass

If more people knew how sharp Sigma lenses are, more people would use them and forget about the whole weather sealing argument

AND my Nikon 55 f1.2Sure, Sigma has had problems in the past

I have a Sigma 35mm Art that works great, and a Sigma 15mm 2.8 fisheye, also fine.

it was really really sharp as I

(I also think it's way better than Sigma's non-ART 50, which I found worse than Nikon's 1.4G in terms of its low light autofocus ability as well)

I later tried the Nikon 50mm 1.4G and I was not happy with its performance, I then owned the Nikon 1.8G and although better than the 1.4, I never really fell in love with that one

And it's very inexpensive - nearly as good as the Zeiss Otus 55mm f1.4 but with autofocus and at

Beautiful lens, accurate focus, sharp as the 35mm 1.4

If they make a 85mm Art, I will order it as soon as it's available as 50mm on a full frame camera is not great for portraits in my opinion where an 85mm on full frame is great for portraits.

Chances are you'll find that some of your lenses aren't performing quite as well as they could. :

Just keep in mind that F1.4 on a full frame body will have significant out of focus blur, so the picture may not have come out as sharp as you'd like due to this reason
