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.Customer Review: See Review at dpreview.com. Excellent lens!
I'm saving up to buy this lens. Right now, I own the Canon 50mm f/1.4, which is an excellent lens for the money (especially since I got it for only $200, never used), but the published review at dpreview.com convinced me. The bokeh on this lens looks fantastic! I also own the Sigma 30mm f/1.4 EX DC HSM, which is an amazing lens. The build quality is fantastic, as are the photographic results. The only negative I had for that lens is that it's made only for "cropped sensor" cameras (APS-C), and won't work well with full-frame cameras. The 50mm DG won't have that problem, so should be an even better lens for most people. I've fallen in love with the build-quality of the Sigma EX lenses (EX lenses are the high-quality Sigma lenses). The DC in the 30mm f/1.4 means it's made for the APS-C sensor cameras, while the DG in the 50mm f/1.4 means the lens has been made specifically to correct digital-camera-specific issues, but the lens will work on all sensor sizes.
Customer Review: Beautiful, sharp, fast, and fantastic bokeh
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.
After filling your camera with photographs you need to take camera to the store in order to get them printed out which can become a major hassle. As technologies improved, digital cameras became more available to the public at cheaper prices that most people could afford. Thanks to these improvements people could begin printing their own photographs at home. Of course, the idea was too good to be true. Photographs printed from a digital camera at home were often flawed with downgraded quality. The quality of the cameras and printers are usually what influences the outcome of the photos. The lower the quality of the camera and printer the lower the quality of the printed photos. In recent times, the price of digital cameras and printers has dropped while the quality of these devices has improved greatly. The photo printer was also released for the first time and people quickly fell in love.

There are very little requirements needed to use a photo printer. All that you really need is a digital camera and some disposable models are also compatible with such printers. Many people were thrilled when they realized that a computer wasn't among the requirements. Of course, a special type of paper is needed to give the photo the authentic look of store processed photos. Anyone who has ever used a printer knows how much ink is needed to printed all the photographs and documents desired. It is a good idea to go ahead and stock up on ink cartridges because you'll need one after printing a small number of photographs. Of course, many people overlook the ink problem. Those who do will be happy go to with photo printers over photo centers any day of the week.
Before finalizing a purchase you much determine whether or not a photo printer is capable of meeting of all of your needs. People who intend on printing a large number of pictures will end up saving money in the long run. Those who only need to printed pictures ever so often might find that the photo center works better for them. People only printing photos ever month of so will definitely want to stick with the photo center and save a little money. A good photo printer will cost you over one hundred and fifty dollars. There is no reason to spend that amount of money on a printer if you aren't going to be using it very often. You will also need to take into consideration the cost of ink cartridges which can cost a pretty penny.
Of course, there are other alternative out there. People who are only printing a few photographs ever now and then might find that an all in one photo printer is capable of doing what they need to get done. These printers are great for almost anyone since they are so well rounded. The printer is capable of doing virtually anything. The printer is capable of copying photos are well as performing all the tasks performed by normal printers. This is like buying a Hewlett Packard printer that is also equipped with a photo printer. These types of printers usually cost a little more than others but they can deliver nearly flawless quality photos. Every one in a while you'll need to make copies of something, so this printer will come in handy in that department as well. When shopping around don't just purchase the most expensive printer you can find. Try to match the quality of you camera with the quality of the photo printer. A good quality printer and good quality camera will allow you to print excellent quality photographs right from your own home.
