Autofocus could be faster
comment:I bought this lens for shooting wide open on my A99, which I can't with the old Sony 50 1.4. After the first few test shots I noticed many photos weren't track sharp. After many test shots in various lighting conditions, micro-adjustment, comparison with Sony 50 1.4 and Minolta 85 1.4 lock-on, I was sure it wasn't locking focus accurately. I even switched the AF on the A99 to slow and waited a fraction of a second longer for it to focus (after the beep), it improved accuracy but was still getting some missed shots in all sorts of conditions.
I finally compared to a Sigma Art 50 on a friend's Canon 6D and it was flawless in his.
So I returned the lens to go for the Zeiss 50, with the advantage of having a much wider AF area on the A99 II.
As a professional I can't rely on a lens that doesn't give me confidence I can get the shot.
My build rating reflects only on the AF accuracy.

price paid:£530.00
positive:EVERYTHING except size.
negative:It's huge but who cares.
comment:The best 50mm currently available for A mount and FE mount cameras (via the LA-EA4 adapter).

Note...The LA-EA3 adapter does not offer autofocus at all with this lens or the 35mm Art lens.

compared to:Sony Zeiss 50 1.4
price paid:650
positive:1) Sharpness and more sharpness. This lens has detail to beat the band, and with excellent microcontrast.
2) Great build quality. Proverbial brick sh-- house.
3) Easy to very finely MFA with USB Sigma dock (four different values possible).
4) Excellent control over CA (better than CZ 50 1.4).
5) Great value for the $. Better lens overall than pricier CZ.
negative:1) Weight and size. Big as some 24-70's? Instead of 'Nifty Fifty' Sigma must have thought of 'Chunky Monkey?'
2) Not much else to speak of, except that Sigma may not be making these any more for A Mount, such that once stock runs out, that may be it. If so, that's very disappointing and suggests that you should get one NOW.
comment:The Sigma 50 1.4 Art, like all the Sigma Art series lenses, is a value 'home run'. This lens is $500 less than competing (and admittedly excellent) Zeiss 50 1.4, but is sharper in the corners at virtually any aperture, with about the same central sharpness. Easier to MFA precisely, given firmware dock. Won't allow H-AF on the A99ii obviously, which is a significant downside compared to the CZ, but only if shooting in wide modes and wanting features like eye focus. Works great with PDAF 79 AF points, so I don't miss H-AF at all. As for the weight, it's all tradeoffs. Can't get this kind of optical quality, including particularly wide open sharpness, without big elements.

compared to:CZ 24-70
Sigma 2.8/70 Macro
Sony 1.4/50
Sony 135 STF
price paid:500 Euro
positive:Sharp, silent AF, solid build
negative:Size, no weather sealing
comment:The lens is huge compared to the old Minolta/Sony 1.4/50. It has some heft to it that may be deal breaker. It does, however, balance well on a full frame body.

The AF is silent and swift but not very fast. The Sony 1.4/50 acquires focus as fast as the Sigma, if not faster. The CZ 24-70 is faster to focus too. You might want to fine-tune the AF but that's no lens fault.

The bokeh is very fine but not rocking. Of course, subject isolation is easily possible and a 3D effect can be achieved.

Despite being so conveniently small the Sony 1.4/50 never convinced me. When shooting wide open I got images that have been a bit on the soft side. I don't hesitate to shoot the Sigma at 1.4 - it's very shard, it's great...

Build and finish
Tough as nails
negative:Heavy, really heavy.
comment:Only just got this lens but straight away I can see it is so Sharp and love the whisper quiet focus.
Have put 4 for flare control but tbh it was probably me more than the lens.
Lens is heavy but have got used to that quite quickly.

Update: This is one tough lens. Tripod fell over the other week, had Sony A7R, Sigma 50 ART and NISI filter system attached. The filter smashed to bits camera suffered a broken mount requiring repairs. Filter adaptor ring was ripped out of the lens but the Lens doesn't have a mark on it. The filter thread is still perfect and the lens still works.

comment: I got to use this lens for a weekend. It is easily as sharp as my Sony Zeiss 50 1.4. The flare resistance, distortion and bokeh are second to none. The image quality versus price is really surprising.

compared to:Minolta 50mm 1.7
price paid:950
positive:Sharpness, color, sharpness, contrast, low distortion, vignetting, manual focus override.
negative:Slightly sticky focus ring. Slow focusing. Big for a 50.
comment:This lens is phenomenal for shear image quality. The contrast and sharpness is out of this world good. It is so much better than my current Minolta 50 1.7 that I feel like I have a new camera. Yes this lens is big but it is no bigger than your average 24-70. On the A99 this lens seems very well balanced. On the A58 it feels a bit ridiculous. The Sigma is significantly slower than the Minolta in focusing. As long as you are dealing with high contrast items. With lower contrast targets the Sigma seems to do slightly better at locking on. Overall the build quality is fabulous. But to me the focus ring leaves something to be desired. Wish it was more silky smooth with longer throw as the short throw and slight stiffness can make it difficult to make very fine adjustments when wide open. Love the big focus ring though. The focus ring on the Minolta is almost impossible to use as it is so thin it is hard to find. If you have the money for this lens and fast focusing is not critical for you I highly suggest getting it. The Sigma makes my Minolta look like it has Vaseline smeared across the lens. I haven't had this lens for too terribly long as it just came out for A mount so I will update with anything that comes to light.
