Canon EF 50mm f/2.5 Compact Macro Lens Want to bring small things into full-sized view? Turn to the Canon EF 50mm f/2.5 compact macro lens, which can uncover detail that would otherwise be impossible to detect by the naked eye. Ideal for shooting extremely minute subjects such as insects or the petals of a small flower, the lens offers a nine-element design and a floating optical system that focuses down from infinity to one-half life size (0.5x). Despite these macro optics, however, the lens also functions beautifully as a general-purpose normal lens. And should you want to focus down to life size (1:1), you can add an optional Life Size Converter EF to increase the working distance–a valuable feature in close-up shooting. Other details include a 46-degree diagonal angle of view, a 0.8-foot close focusing distance, and a one-year warranty.

Customer Review: Macro Away. I use the lens for close up product shots for a business that my partner runs. I also use it for shots of my work for my portfolio. It is versatile and takes very clear pics. Overall I really enjoy using it. Customer Review: Nice little lens for the price. I’ve been looking for a reasonably priced macro lens for taking pictures of my husband’s scale models, and wanted to get all of the fine details that a macro lens can find.

Customer Review: First(ish) L I bought this lens just about a month ago after an endorsement from one of the teachers at a photography class I was taking. (The fact that I was taking an introductory photography class should give you some sense of my skill level, and hence perspective…) I’d previously purchased and returned the 300M L, for both quality and usability issues.

Customer Review: Good Canon L Lens but not for the price. Again, Canon L lens will never disappointed any photographers this 16-35mm f/2.8L II USM is no exception and it will allow you to shoot in very tight pace without moving back, I had a chance to try it from my friend while I have my own EF24-70mm f/2.8L USM. This 16-35mm is going to give you super image quality with just a little distortion that you can’t barely notice until you enlarge final print, to me it’s nothing better than canon 24-70mm F/2.8L USM. Except its version II. I have also thanks to my best friend allows me to try it before I decide to make some upgrade. I’ll keep my own. Here is some side by side comparison, so future users could use some help.

Customer Review: Definitely worth it. I own a lot of L series lenses from Canon and love this lens. I used it for a year on my 40D and was pleased, not extatic. Upon upgrading to the 5Dm2 I became extatic. The quality is great on a crop factor but when you compare it to the full frame, you will notice the difference.

The lens construction, meanwhile, includes UD and aspherical elements that deliver impressive image quality throughout the entire zoom range.

Finally, the lens offers a ring-type ultra-sonic monitor (USM), inner focusing, and new AF algorithms to help achieve autofocus quickly and quietly, along with full-time mechanical manual focusing that makes it possible to manually adjust the focus even in AF mode. As with all Canon lenses, this lens carries a one-year warranty.

Customer Review: Perfect Lens for a 1.6 crop. I purchased the 17-55mm about a month ago, and was very happy with the quality of images the lens produced. I like night photography and the f/2.8 helped alot, even when shooting without using a tripod. There are alot of good things to say about this lens, i know alot of people are in love with it, maybe because it’s one of few lenses that Canon produce for the 1.6 crop cameras? Well on day 2 of having the lens, i was shooting outdoor and noticed a few dust particals behind the front glass. It was not fun to see dust from the 2nd day of getting the lens, specially after paying that amount of cash. I kept using the lens for almost 3 weeks, and everytime i shoot outdoor i noticed more and more DUST particals in my lens. So i decided to return the lens for a full refund. Amazon did the refund very fast, it just took like 2-3 days to get the money back. Thanks Amazon for a great and honest support. Well after getting the money back, i placed an order for 2 other lenses from Amazon. EF 17-40mm f/4L USM and EF 50mm f1.4 USM. I just could not stand the dust issue, and i have read that they won’t effect the image quality or the foucs. I also have friends that have been using this lens for a while now, without having the DUST issue. I guess i was not lucky.

Canon EF 85mm f/1.8 USM Medium Telephoto Lens for Canon SLR Cameras A highly practical medium telephoto lens with superb delineation and portability, the Canon EF 85mm lens produces sharp and clear images at all apertures. Through computer simulations, the lens has been designed to give beautiful background blur, thereby bringing your subject into crisp view. The ring-type ultra-sonic monitor (USM) and fast f/1.8 aperture, meanwhile, helps the subject zip into focus in the viewfinder. And because the front lens group does not rotate during focusing, special filter effects are not affected. Best of all, the standard zoom lens–with its natural angle of view and perspective–captures the subject plainly, making it excellent for portraits and images that require a natural depth of field. As with all Canon lenses, the lens carries a one-year warranty.
- Focal length: 85mm
- Maximum aperture: 1:1.8
- Lens construction: 9 elements in 7 groups
- Diagonal angle of view: 28 degrees (at 30 feet)
- Focus adjustment: Rear focusing system with USM
- Closest focusing distance: 2.8 feet
- Filter size: 58mm
- Dimensions: 3 inches in diameter, 2.8 inches long
- Weight: 15 ounces
Customer Review: Great lens for indoor sports Got this lens for high school indoor volleyball and basketball games. I love it so far. The focus is fast, f1.8 is great for some of the poorly lit gyms we play in, and the 85mm length is just right for taking pictures from the stands. The only con I can think of is that working with a prime lens takes some getting used to - You have to think ahead about where to position yourself for different types of shots since you can’t just zoom in and out. Also as others have noted on this and other lenses the focus can be a little soft when it’s wide open at f1.8. At f2.0 and f2.2 I could still use a fast shutter and get really sharp pics. Customer Review: Brilliant lens for portraits This lens is brilliant for portraits. The background blurrs out and the object really stands out. Wonderful. This is the best lens for photographing people from a close angle. Yet, I had to get used to the focal distance of 85mm because you can’t zoom in or out!

The lens is distinguished by a ring-type ultra-sonic monitor (USM) drive that provides silent, high-speed autofocusing, along with full-time manual focusing. The 1.6-foot close-focusing distance, meanwhile, lets you take great close-up portraits and nature shots. A good match for the Canon EOS A2/A2e or ELAN 7 series cameras with built-in flashes, the EF 28-105mm lens is an excellent zoom lens for everyday use. The lens carries a one-year warranty.
- Focal length: 28-105mm

Canon EF 75-300mm f/4-5.6 III USM Telephoto Zoom Lens for Canon SLR Cameras This compact and lightweight EF 75-300mm telephoto zoom lens is ideal for shooting sports, portraits, and wildlife. The lens is distinguished by a newly developed micro ultra-sonic monitor (USM) that makes autofocusing quicker and quieter, along with an improved zoom mechanism that includes a silver ring on the front for a luxurious touch. The micro USM makes this version of the lens particularly suitable for applications that require a fast autofocus, such as sporting events or wildlife shoots. Best of all, the USM version shares many of the same features that makes the non-USM lens so popular, such as a compact size, a close focusing range, and accessory compatibility. As with all Canon lenses, this unit carries a one-year warranty.
- Focal length: 75-300mm
- Maximum aperture: 1:4.5-5.6
- Lens construction: 13 elements in 9 groups

Canon EF-S 60mm f/2.8 Macro USM Digital SLR Lens for EOS Digital SLR Cameras Bring small things into full-sized view with the Canon EF 60mm macro USM lens. Macro lenses can uncover detail that would be impossible to detect by the eye and give new perspective to extremely minute subjects such as insects or the petals of a small flower, and this lens is no exception. The 60mm lens offers an angle of view that’s equivalent to a 96mm lens on a 35mm camera, along with a floating optical system that can focus down to life-size 1:1 magnification. The inner focusing system, meanwhile, is driven by a silent and powerful ring-type ultra-sonic monitor (USM), meaning the lens’s overall length never changes during focus. Ultimately, the multi-purpose lens is equally at home shooting macro shots, portraits, or available-light photos. Like all Canon EF-S lenses, this lens is restricted to the EOS 20D, EOS Digital Rebel, and EOS Digital Rebel XT cameras.
- Focal length: 60mm
- Maximum aperture: 1:2.8
- Lens construction: 12 elements in 8 groups
- Diagonal angle of view: 25 degrees
- Focus adjustment: Manual
- Closest focusing distance: 0.65 feet
- Filter size: 52mm
- Dimensions: 2.9 inches in diameter, 2.8 inches long
- Weight: 11.8 ounces
