Para manter alta performance ótica em fotos de infinito a close-up 1:1 macro sem acessórios, a Sigma 50mm f/2.8 EX DG incorpora um sistema de "Focagem Interna Flutuante" (FIF). Como resultado a lente também possui um grupo de lente frontal não rotatória que facilita trabalhar com filtros polarizadores e possui um limitador de foco para estreitar a ampla faixa de foco. A abertura mínima melhorada de f/45 agora oferece profundidade de campo melhorada.
Essa lente foi projetada como uma lente macro primária de alta qualidade, boa para câmeras digitais SLR ou de filme. O design de lente DG aprimorado corrige várias aberrações. Essa lente macro foi especialmente revestida para obter o melhor balanço de cor reduzindo o fantasma causado por reflexos do sensor de imagem digital. A lente oferece a melhor correção contra aberração cromática lateral que é um problema sério para câmeras SLR digitais.

Purchased for general use as a 50mm normal lens, and macro work. Used with Canon Digital Rebel and 5D MkII bodies. Initial use on my 1.6 crop factor Digital Rebel body showed good, but not great results. The 5D MkII full frame sensor body exhibited better results, but not as good as I had hoped! After examing numerous pictures taken with the 5D MkII body, it was apparent the lens was "front-focusing I ended up setting the focus "microadjustment" to +5 (toward back) on my 5D MkII body, and the image quality is now excellent and actually better than I had expected. I also noticed degradation when using an old (but good!) Hoya Skylight filter, which seemed to cause the focus to revert back to "front-focusing."
This Sigma 50mm macro lens is capable of producing extremely high quality images, but is very sensitive to mis-focusing. I had no difficulties with autofocus other than the slight front-focusing on all pictures, which I resolved with the body microadjustment. Focusing at far and macro distances is now extremely accurate, but can be slow. For macro work it is generally better to focus manually, so you can center your depth of field.
The hood is OK and will accept a 72mm lens cap, unlike what some others say! Use 55mm filters on the front of the lens, and NOT on the hood! Placing a 72mm filter on the front of the hood will create flare issues!
The image sharpness produced with my "microadjusted" Canon 5D MKII is fantastic and uniform from center to edge at all apertures, from infinity to 1:1 Macro:
F2.8 VG
F4.0 VG to Excellent
F5.6 Excellent
F8.0 Excellent
F11 Excellent
F16 VG to Excellent
F22 VG
F32 & 45 F to P (Don't know why Sigma even included this capability!)

The depth of field is absolutely tiny with the f-stop at 2.8, which can be a lot of fun. The color is a bit off and the pictures can be a bit soft, even at higher f-stops.
One great feature that doesn't get mentioned is that it has a max f-stop of 45! Sounds impractical, but when you want to take a photograph of something stationary surrounded by a lot of moving objects, you can get a really pretty picture @ f/45 30s shutter.
I have nothing good to say about the autofocus. The autofoucus is terrible, especially in macro and I've found the it focuses slightly in front of the subject in a portrait type setting. It's incredibly noisy and it takes forever to focus, due to its wide focal range and slowness.
For the price, I recommend this lens, but if price isn't a concern, you want the Canon 100mm.

Comments about Sigma 50mm f/2.8 EX DG Macro Autofocus Lens for Canon EOS:
This lens takes great photos, but the build quality is mediocre. The plastic construction is not bad, but metal would have been better.
Also, if you attach the lens hood, you are no longer able to attach the lens cap. Finally, the front element moves quite far during focusing, which can make close-up work trickier.
With that said, for the price, this lens takes excellent photos, with no distortion and almost no chromatic aberration.

Comments about Sigma 50mm f/2.8 EX DG Macro Autofocus Lens for Canon EOS:
I am a professional photographer still building up my gear. I have wanted a macro lens for some time now. This camera is a great lens for the price. I couldn't ask for more. I was debating between this lens and the same model from Canon, what ultimately determined my decision was the fact that the Canon lens needed an additional $200 adapter to use the lens. Having to work on a budget, I decided that this was the lens for me. I can get within inches of my subject filling the field with my subject and the focus is not inhibited, I am very happy with it.

Comments about Sigma 50mm f/2.8 EX DG Macro Autofocus Lens for Canon EOS:
This lens came highly recommended from a photo shop in my area. After being given the opportunity to take some pictures using theirs, I was sold and had to have one for myself. The clarity of the close-ups is amazing and simple to use. Just aim and shoot. It has a fast focus rate for what I am using it for. I enjoy taking close ups of Hot Wheels and family portraits. I use the lens on my Canon Rebel Xti and couldn't be happier. For the price I paid, there are no cons.

Comments about Sigma 50mm f/2.8 EX DG Macro Autofocus Lens for Canon EOS:
I use it for portrait as its focal length gets similar to 80mm in my 30D. Very sharp. It shows higher contrast than my Nikkor 55mm f/2.8 AIS micro. Should adjust it!

Comments about Sigma 50mm f/2.8 EX DG Macro Autofocus Lens for Canon EOS:
Had my first chance to use this lens today. Winter in the Northwest doesn't lend itself to photography much of the time. No light. That said the lens is sharp and reasonably quick on autofocus and the small apertures make for a good depth of field. The initial test pictures I took while no works of art seem to be sharp and the detail is certainly there. You could see small water droplets on moss seed pods. Point here is you couldn't even see the water with your eye. The price is right. One thing, at 50MM while it gets in reasonably close a little more length might be nice and is probably a good excuse to get a longer lens latter.

Comments about Sigma 50mm f/2.8 EX DG Macro Autofocus Lens for Canon EOS:
I bought this lens for taking close up shots of flowers, fungi, jewelry, etc. and it performs the intended task perfectly! Love that I can stop down to 45 which, combined with a slow shutter speed (2"-3") gives me greater DOF on those really close up shots. Wide open shooting produces decent bokeh, too.
Looking for a great Prime lens that can focus 1:1? Then this one is for you !
The nice surprise was portraiture results- great overall lens.
I saw the focus complaints above but, while it may be slow and a little loud, really doesn't bother me; the auto-focus yields crisp results.
I highly recommend this lens for Macro, as wel as other, uses...

Comments about Sigma 50mm f/2.8 EX DG Macro Autofocus Lens for Canon EOS:
This is my first non-kit lens for my Canon Rebel XS. I did weeks of research before deciding which lens to get within my <$500 budget. At first, I was a little nervous about getting a third-party lens, but the reviews and price were so good, I had to go for it. I couldn't be happier.
I wanted a true macro (1:1) for photographing interesting small things (tree bark, wood grain, leaves, grass, rocks, flowers, wool), and this lens delivers. I can get an inch away from a subject and get a professional-looking photograph. It also captures portraits sharply, so it functions quite well as an all-purpose lens.
The autofocus tends to adjust a lot before finally focusing in, which has caused me to miss a few shots. But on the manual setting, this isn't a problem, of course. And I was also a little worried about the description not mentioning image stabilization, but with a fast shutter speed, I haven't had any problems.
Bottom line: with this lens, I can be creative, even as a newbie. Truly a great buy.

At first I was disappointed, but after pulling out the tripod and taking some still Macro shots, I was quickly won over. The pics are amazing!
Definitely not for chasing bugs, but for still objects with a tripod and you'll be a happy customer. Oh, and this works very well as a portrait lens.
