Canon EF 50mm f/2.5 Compact Macro Lens 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.

Specifications

  • Focal length: 50mm
  • Maximum aperture: f/2.5
  • Lens construction: 9 elements in 8 groups
  • Diagonal angle of view: 46 degrees
  • Focus adjustment: Front group linear extension system with AFD
  • Closest focusing distance: 0.8 feet

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.

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.

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.

Canon EF 85mm f/1.8 USM Medium Telephoto Lens for Canon SLR Cameras 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.

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 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
  • Diagonal angle of view: 32 degrees (at 11 feet) to 8 degrees (at 15 feet)
  • Focus adjustment: Front group rotating extension system with USM
  • Closest focusing distance: 4.9 feet
  • Zoom system: Rotating type
  • Filter size: 58mm
  • Dimensions: 2.8 inches in diameter, 4.8 inches long
  • Weight: 16.8 ounces

Customer Review: Works as designed.
It’s a great lens, and the USM motors really do help you focus a lot faster, but still not quite as fast as the smaller lenses.

Canon EF-S 60mm f/2.8 Macro USM Digital SLR Lens for EOS Digital SLR Cameras 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

Tamron AF 17-50mm F/2.8 XR Di-II LD SP ZL Aspherical (IF) Zoom Lens for Canon Digital SLR Cameras Tamron AF 17-50mm F/2.8 XR Di-II LD SP ZL Aspherical (IF) Zoom Lens for Canon Digital SLR Cameras The Tamron AF 17-50mm aspherical lens expands on the popularity of the AF 28-75mm f/2.8 XR Di zoom, with a 17mm focal length that offers a wider angle of view than an ordinary standard zoom lens. Designed exclusively for digital SLR cameras with smaller-size imagers (24 x 16mm or smaller), the 17-50mm standard zoom is extremely lightweight and compact for its speed. And with a fast f/2.8 maximum aperture throughout the range, it delivers fast shutter speeds and a natural soft-focus effect that makes your photography even more sophisticated than usual.

Superior image quality
Constructed with cutting-edge Tamron elements–three elements of XR (extra-refractive index) glass, two hybrid aspherical lens elements, and one element of LD glass–this elegant piece of technology inherits Tamron’s tradition of premium image quality and compact size. By incorporating Tamron’s SP (super performance) and Di-II (designed exclusively for digital cameras) specifications, along with special internal surface coatings to eliminate ghosting and flare, you’re guaranteed to get the superior performance you need from your digital camera.

Broadening your horizons
Tamron’s SP AF17-50mm offers a wider angle than the standard 18mm zoom lenses ordinarily used with digital cameras. With a wider-angle focal length of 17mm (26mm equivalent), this lens is unbeatable for indoor photography, and for capturing full-length people shots or an entire building. The lens is also top-level in its class for minimum focus distance at 27cm (10.6 inches) across the entire zoom range, making it easier than ever to enjoy the creative combination of wide-angle and macro photography.

Customer Review: Quality Control Issues
After reading all of the front focusing issues some people were having - I still took the plunge and gave this lens a shot. It really seemed like a good value and I hoped for a good copy. Well, I received the lens and of course immediately tested it to see if it had any focus issues. Without a formal focus test - there was an obvious front focus especially at 40-50mm when the subject was more than 4-5 feet away. And it had helluva time locking focus in less than bright conditions (using a 40d).
