"FOCUS" Sigma-son, "FOCUS"
29 August 2013
Summary: I wish this len would learn from Mr. Miyagi, "FOCUS." At close range, about a foot, it works great. But when you step back from that distance and take a picture of your object of interest, ITS NOT IN FOCUS. I've tried different f-stops and shutter speeds, and still it is not truly in focus. My purpose for this lens was to get more wide angle then my NIKON 50mm 1.8f on my D5200. If you are planning to use this as your go-to lens, overall you will be disappointed.
very soft.terrible quality control overall, do not buy or try at least more

Summary: tested 4 of these lenses , they were all VERY SOFT. recently i borrowed the same lens from a friend to give it another try. that one was sharp. also recently Sigma advertises with ; "enhanced quality control" . nice they more or less admit the previous era was terrible! And indeed the latest sigma's (end 2012, start 2013) are generally much better in IQ and QC.
Summary: I read all the reviews online and comments in this area for this lens and I decided to give it a shot. It appears well built and connected quite securly to my t3i. I was having difficulty with a bit of front focusing on my first copy but I decided to give it a long trial period. Well I went out on a shoot and found that at key moments (when I wanted to focus on a ring) it would put other things in focus and not where I had actually locked focus on.
Summary: I purchased this lens as a good low light and portrait lens. Unfortunately, after thorough testing the sharpness was not up to par. At first, I thought it was me, so I took a few sample shots. My first sample shot was a close distance (5 ft) handheld. I had a low light shot using f/1.4 and 1/100 and my focus points were a little shaky. Most likely my fault since it was hand held. My second sample shot, I got a tripod and stopped it down to f/2.8.
Summary: I wanted to love this lens. Sadly, it simply doesn't perform well. The focus issues with this lens have been written about ad nauseum, but I found that the focus issues manifested themselves differently than what I'd read here. It's not that the lens doesn't focus - it's that it focuses on the wrong thing. I was shooting this lens on a D40, which has five-point autofocus.
Summary: I used this lens on my XTi with good results. After upgrading to a 40D, many of my shots were not focused properly. I thought it was the camera but it (apparently) was not. The lens is great from f4 to f16. But from f1.4 to f2.8 the images were not sharp. This was with careful testing using tripod, focus charts, remote shutter release, etc. It's not my failure to understand depth of field. I returned the lens.
Summary: The item was broken when we received it and because it was from a supplier in Germany the returns policy was very complicated. I ended up sending it to Sigma to be repaired at around £80. 2 Months on something else went wrong with the lens. I'm sticking to Nikon from now on even if it means I have to save up for longer, because at least I'm guarantee quality.
You must read this review before purchasing the Sigma 30mm
Mac Porteiro, Amazon

Summary: Length:: 3:48 Mins I lost count of how many times I've purchased items here in Amazon, and this is the first time I have a problem with a product. You should definitely read this before buying the Sigma 30mm F1.4 (Nikon version), or be happy with the consequences. Despite the positive reviews around the web, this lens has a SERIOUS focusing problem.
Summary: I really wanted to like this lens. I already own a canon 50mm f/1.8 and a canon 85mm f/1.8. Going at 30mm and at a wider aperture seemed like a nice idea. For those low light conditions and when there is not enough room to step back. The good: Nice build, lens hood included, well padded pouch (if you are into that staff) The bad: Back focusing issues. Here's how I tested this. I used a canon 550d (T2i). All the tests were at f/1.4.
Excerpt: По снимком от Canon объективов сильно отстаёт(картинка другая). Купить экземпляр с фронт или бэк фокусом проще простого. Мыльные края(сильно). Тёмные пятна по углам снимков. Описаные мной проблемы характерны для всех объективов sigma 30 1.4. Другой вопрос, что за такие деньги найти аналог почти невозможно, а поиграть с 1,4 хочется.
Pros: Светосильный Корпус 30mm 1,4
Cons: По краям жуткое мыло в плоть до f/4 Жуткое виньетирование на открытой. В солнечный день фотографировать тяжело, хорошо хоть бленду дали, но помогает мало. Некрасивое бокэ Иногда мажет фокус Тяжёлый Абберации
