Product Description
This is a large aperture prime lens with a standard focal length of 50mm, ideal for all digital SLR cameras. This lens has superior peripheral brightness even at the maximum aperture and corrects a possible sagittal coma flare. This lens is perfectly suited for a wide range of subjects enabling outstanding, sharply defined images against a nicely blurred background. The fast, F1.4 aperture makes this lens desirable for use with Digital SLR cameras. This lens effectively becomes an 80mm medium telephoto lens on digital cameras with APS-C size image sensors. The optimum optical design and molded glass aspherical lens elements provide excellent correction for all types of aberrations. The super multi-layer lens coating reduces flare and ghosting. Superior optical performance is also ensured throughout the focusing range. This lens has a minimum focusing distance of 45cm (17.7") and has maximum magnification of 1:7.4. It creates a very attractive blur, even when a small aperture is used. This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed AF as well as full-time manual focus override.

Beautiful, sharp, fast, and fantastic bokeh August 13, 2008

In a world of zooms, many people would find plopping down $500 for a 50mm prime -- from a third party manufacturer, no less -- to be a bit absurd.
However, if you are a "prime person" -- and you know who you are -- you'll love the performance of this lens: super sharp photos, incredibly creamy background bokeh, nice contrast and flare resistance, and operation in low-light without needing super-high ISO or a blast of flash.
Pros:
+ @1.4 it's quite usably sharp
+ @1.8 and beyond, it's very sharp
+ the bokeh (rendition of out-of-focus areas) is really amazingly smooth. More so behind the DOF than in front, though
+ colors, contrast, etc, all excellent
+ great build quality, solid feel, free case and lens hood
Cons:
- weight
- price
- big filters (77mm)
Canon already has three 50mm lenses: the 1.8, 1.4, and 1.2L, so you might wonder why Sigma felt the need to jump into this market. The Canon's are all pretty good, with the 50/1.8 being an great value at $80, the 50/1.4 being a reliable workhorse (though prone to a dreamy look wide open), and the 1.2L, being, well, $1500. This lens is priced between the 1.4 and 1.2L, and judging from photos I've seen, it probably performs in that range as well. So it is filling an niche in the wide gulf between the 1.4 and 1.2L.
On my camera, a 400D, a 50mm is like a short tele, and I use it mostly for relatively close up photos of people. I like that when if upgrade to FF, I'll be able to continue to use this lens (and I'll sell my Sigma 30/1.4) whose place it would take.
The lens has not been out very long, and, to my knowledge, no formal reviews have been published (8/2008), but the general "buzz" is that people are seeing AF problems at distances beyond a few meters subject distance.
I personally have not done exhaustive analysis, but I feel my copy performs quite well. Then again, I don't use this lens for far-off subjects very much, and almost never wide open in that case. So there may indeed be problems with this regime, but I don't feel it affects my photography much. That said, it could be that I'm just not as exacting as some, or my camera's AF is sloppy enough to hide lens variation to begin with. However, I do pixel peep a lot and I get about the same hit/miss rate as I do with other lenses I own.
So far, I'm a happy customer.
