Full frame sized imageLenses that create APS-C sized image are designed for digital only. They cannot be used on cameras that have image sensor larger than the APS-C format. These lenses are not suitable for film cameras either. No Ultrasonic AFLenses with ultrasonic focusing mechanism tend to be quiter and faster than traditionally focusing lenses. No Low Dispersion lens element is usedLow Dispersion lens elements help to reduce chromatic aberration. Not stabilizedImage stabilization helps to reduce blur caused by hand shake, especially at high focal length or in low light situations. Image stabilization can give 1 to 3 stop advantage over none stabilized lens, based on the reciprocal rule. Metal mountCheaper lenses are usually equipped with plastic mount, while more expensive, professional lenses have metal mount. In general, metal mounts are more durable, and a good thing to have when lenses are changed a lot. When a camera is used mainly with one lens, the material of the lens mount is not that important. No Internal FocusingInternally focusing lenses don't change their size while setting focus. The front lens is fixedThe fixed front lens is not rotating during zoom and/or focusing. This allows the photographer to use petal shaped lens hood. Fixed front lenses also make the use of polarization filters a lot easier. Not SealedWeather sealed lenses are protected from dust and water. While they are not water proof, these lenses can be used in rain and other humid environments. Some sealings only provide protection against dust or water, not both. Sealing is only available when the lens is used on a similarly weather sealed camera body. No drop-in filter supportDrop-in filters are used in those lenses where either the front lens is too large, or the field of view doesn't permit the use of traditional filters at the front of the lens. Usually bright tele and ultra-wide angle lenses support this filter type. |

I purchased this lens back in March of 2005 to shoot static "Warhammer models" with my 10D. I found that longer lenses such as the Sigma 105mm, the Canon EF 100mm, and the Tamron SP Autofocus 90mm all were "too long" with the 10D's 1.6 focal crop and would result in requiring me to use a lot more physical space that what I had room for to get the shot.
The Canon EF 50mm f/2.5 is nearly a perfect match with the 10D for this purpose. Its small, its compact, and its short focal length do not require that I be standing three feet away from the model I'm shooting.
As far as shooting at non-static objects, such as insects, the lens is slow to focus and loud, in both noise and vibration, which results in "startled" subjects and missed shots.
The same also applies for non-macro shots as well. Its slow focus makes it a poor choice for action photography, and its loud enough to draw attention to you when you are attempting other shots as well.

I never thought a $250 lens could be so good. I have been trying to buy lenses that are light-weight for my 20D, due to a neck injury problem, and this 50mm fits the bill.
Great in low light, and agree also, the bokeh is sweet. I do alot of bee chasing and manage some great macros with bees in flight with this one. All hand held. Can also take great indoor shots without flash, with a steady hand.I chose it also because it was one of the least expensive high rated canon 50mm's.
It goes well with another inexpensive canon lens, the 55-200mm ef f4.5-5.6 II, which also does well outdoors, including macro.
I am very pleased with both, and wouldn't part with them!

I bought this lens to go with my Canon Digital Rebel XT. I absolutely love this lens. I got it to try some insect and other macro shots and it has served this purpose very well. With some practice this lens will produce fantastic macros with some great bokeh to boot.
I read the other reviews and must say that I have never scared an insect away with the noise as mentioned before. And I have taken countless insect shots with this lens. It is a bit louder than the other lenses I have but I don't see it to be a problem. The one problem I do encounter is when using the autofocus in a busy closeup scene it often will focus on the background instead of say a closer insect on a flower. When this happens I just flip it to manual and focus that way. No big deal.
Overall, great lens for an even greater price. Definitely worth it. (I submitted a photo of a bee that I took a couple of days ago with this lens as an example.)

I bought this lens around three months ago for use with my Rebel XTI/400D. It has produced some nice shots and has great clarity and bokeh for portraits and the like. However, in this area it is really only as good as the "nifty fifty" 50mm f/1.8, which you can get on here for about $90.
For me, I like to take shots of insects and other animals that tend to be skittish. For that type of work, this lens is loud and finds it tough to focus quickly, so you need to work in manual mode. By the time you get the shot, the subject has moved out of the position you were after. Also, you don't get true 1:1 macro, so the details are not as good as if you fork out the extra for the 60mm Canon f2.8 Macro USM, which has the ultra quiet focus.
A recent review I read in a prestigious magazine put this lens a distant second to the Sigma Macro 50mm f2.8 EX DG, which costs about the same as this one and offers true 1:1 macro. If I could go back and buy that one I would.

I purchased this lens to take photographs of vintage wristwatches. I use an original Canon Digital Rebel and the shots are really very detailed. It is easy to use in fact, I can hand hold the camera and capture the details in the hand-made craftsmanship of the watches. Its F2.5 opening is a welcome change when you are use to shooting with a zoom lens and it is quite sharp edge to edge. If you own a Canon digital SLR and want to pocket some extra coin then this is the lens for you.
