Summary: I had high hopes for this lens after purchasing a 35mm 1.4 Sigma Art lens which was spectacular. Long story short, it was front focused pretty bad and my first 30 test shots were all out of focus at 1.4. Got a calibration target and started tweaking the micro-focus adjustment. The max my camera goes is +20 and that yielded the best results. I was able to get it even sharper by using manual focus so I think if I could take it higher than +20 it might be even better.
Summary: While researching to buy a 50mm 1.4 i was confused between canon and sigma. I read mixed reviews about sigma and a lot of ppl complaining about front focus or back focus problem, I took a shot at it anyway so I won't have regrets. Here is my take about this lens Cons: 1) the focus really is a hit and miss. I never felt confident that I would get my photo sharp at selected focal point. 2) by no means it is a light or a small lens.
Excerpt: I purchased this lens for portrait work and low light - exactly what a good 50mm f/1.4 is all about. I have good wide angle and telephoto zooms, but prefer primes in the middle (I use 50, 85, and 135). I really wanted to like this lens. Really. So much so that I tried three times to get a good one. All three were plagued by the oft-cited front focus issues to one extent or another.
Summary: Boken is definitely better than canon 50m f/1.4, also slightly sharper than 50/1.4 when you get it right. You buy it for the boken and the depth of the field. Focusing is slower than canon, also not as accurate. If the shooting object can stand still, you will dig out a great photo eventually. However, regarding moving object, you can get it blurred very easily. Although this is true for all lens, it is particular worse with this lens.
Summary: Received the lens yesterday morning. I opened it and was very impressed with the build quality of the lens itself... It is very solid and "heavy". The quality of the lens build is very nice. Comes with a very nice case to store it in as well. Exception to this is the REAR Lens cap and Lens hood are "cheap". They don't seem to fit very well. Lens hood seems like it was just made as an after thought and does not match the build quality at all.
Excerpt: Great bokeh and color, with decent af speed. Build is OK.... I would say that the new Sigmas definitely look and feel better built (my other lens is the 150mm macro which is great also). AF also seems pretty accurate, except for the issue below.<br />OK - the issue, on my D800 and D7000 the Sigma can not focus in Live View mode.... my Nikon 50mm 1.4D and Nikon 85mm F1.8G both work without issues on both bodies.<br />So - definitely a largish issue.
Excerpt: optics are awesome but only when used in manual focus. even at f1.4 i don't find the images soft at all. However, at f1.4 the autofocus makes it seem very soft. i tried 3 copies and all the same. it's too bad cause apart from the autofocus its almost a perfect 50mm. But to some having a usable sharp image is everything. so there is only one downside but a huge one at that.
Pros: Durable, Nice Bokeh, Rugged, Strong Construction
Summary: This is going to be a review from a casual photographer. I have the Canon 5D mark 2 and used the Canon 50mm f/1.8 before I upgraded to this one. I really want to give it 5 stars but I can understand that it may pose some problems for some people. What one notices first is that it is a big lens. I don't want to repeat what everybody is saying but, compared to the 50mm 1.8, this is a brick.
Summary: I seem to have some back focusing and front focusing issues, depending how far you are away from the object. It's not as sharp when wide open on the corners. Definitely better for outdoors because of more light, but not so well in doors, even though it has f/1.4.
Summary: I feel that I should pitch in with this review for the sake of others contemplating this purchase. I purchased this lens as an upgrade to the Canon 50mm f1.8. I mount it on a Canon 7D and in every respect other than focusing it is an AMAZING lens. Colours, sharpness, bokeh!!! are brilliant. However I am just about to return my 3rd copy of this lens.
