This lens is a digital-specific lens designed to provide a normal focal length with a wide maximum aperture on a DSLR with a crop factor. It is not designed to work on a full-frame or film camera. It is the only lens on the market manufactured specifically for this purpose. Other similar lenses are designed as wide-angle lenses that happen to give a normal (~48mm) length on a APS-C size sensor camera. For what it is, this lens is an expensive one, but feels well-made, if not rock-solid. Before buying, make sure you will be making good use of the large maximum aperture. If most of your work is not in low light, another lens might be a better, more economical choice (Sigma makes a 24mm and a 28mm which are f/1.8). In low light, the lens is able to focus decently well, without flopping around. The focusing is internal, pretty fast, and almost silent. Additionally, the lens supports full-time manual focusing adjustment, which means that once the lens has autofocused, you can still use the focus ring to adjust focus without fear of stripping the AF gears. I don't end up using it, but it's nice to have and know that if I bump the focus ring, I'm not shredding the mechanism. Macro-wise, there's not a lot to offer from this lens. Sigma makes similar, slightly wider lenses at f/1.8 that have a macro function, but I've never tried them. Sharpness-wise, it's decent but softish when wide open or close to wide open in low light, but I've gotten lucky and gotten razor sharp focus in good light at f/2.0, which could make this lens a candidate for portraiture. Bottom line: if your favorite film lens was your 50mm f/1.4, this is a natural choice. If your favorite lens was one of the toy Canon 50mm f/1.4 Mark II's this lens feels like much more of a tool and precision instrument; and it costs as much as 5 of those. If you work in low light and need a wider focal length than 50mm and a maximum aperture faster than f/1.8, this is a good lens for you, too. If you use a fullframe camera, don't even bother. Sigma designates this lens as a specialty lens, which I find ironic because what this lens is equivalent to the golden standard in both art and much of documentary photography for years. I guess people are shifting in the direction of zooms with image stabilization instead of more glass and faster apertures, but for those of us in the older school, this may be a good choice.Read full review
I have had this lens for about 2 months at this time of writing my review. This is my first prime lens for my 60D cropped sensor camera and my first non Canon lens. Canon does not make the perfect 1.6 cropped lens. No idea why which is why I was drawn to this lens. This lens has become my walk around lens or the lens that stays on my camera all the time unless I know that I am shooting something specific that requires another lens from my small arsenal. Prime lenses are also good to make you think about framing and composition since there is no zoom. The huge aperture on this lens also is great for low light situations such as shooting in sunset or pre dawn times and does equally well indoors. I am not much of a portrait shooter but I am sure this lens would do great since it is easy to get the classic blurred back ground with this large 1.4 aperture. I find it easy to isolate rocks or foliage from the back ground just the same and at high shutter speeds which makes this a fast lens. I shoot a lot of outdoor and landscape and found this lens to do really well at small apertures all the way to f/16 and the images so far have been coming out sharp, clean and well saturated with color.Read full review
The auto focus os very noisy. If you plan on using it for video, you need to know that. I use lav mics so its not a big deal but know that it would be impossible to use this lens for video/auto-focus with the onboard mic. Way too noisy.

Very nice lens for anything below a Canon 5D Mark II. The 30mm focal length is great since it matches up very close to 50mm. The f/1.4 on this lens gets really shallow depth of field. It's almost so much that it's an inconvenience. Not a bad lens, very well build, and easy to use.
A very good lens...This is NOT the Art,Contemporary or SPORT model....you can NOT use the NEW docking station with this lens. That said, you really don't need it with this lens. Sharp, fast, and a solid build. The second hand price, is fair, and a great value for crop sensor cameras.
