Canon EF-S 10-22mm f/3.5-4.5 USM SLR Lens for EOS Digital SLRs

This exciting new zoom lens provides ultra wide-angle coverage to the EOS 20D and Digital Rebel shooter. Equivalent to a 16-35mm zoom, it offers excellent performance and optics designed from the ground-up for digital SLR use. Three Aspherical lens elements, plus a Super-UD element, assure image quality. Its ring-type USM means fast and silent AF along with full-time manual focus. It focuses as close as 9.5 inches.

Features

• Excellent optical quality and true wide-angle coverage with select digital SLRs
• Superior AF performance and speed, with full-time manual focus by simply turning ring
• Close-focusing to 9.5 inches — fill the frame with subjects as small as 3.6 x 5.4 inches
• Relatively compact size and light weight for an ultra-wide zoom lens
• Inner focusing system (no front element rotation); length doesn’t change if zoomed
• Circular aperture design — natural highlights, even stopped down two stops
• Electronic diaphragm — manually-set apertures stay constant from f/4.5 thru f/22
• EF-S lens mount — exclusively for EOS 20D and Digital Rebel bodies

Canon EF-S 10-22mm f/3.5-4.5 USM SLR Lens for EOS Digital SLRs Review

I am very impressed with this lens. I didn’t realize just how wide-angle this lens was. At 10mm, I can stand just a few feet in front of a 13-story building, and get the whole thing in the picture, from the entrance to the top of the building.

As with all very-wide lenses, you have to be careful that you don’t have people at the edges of the frame or too close to the lens, or they will appear very distorted when taking pictures at 10mm. Also note that a wide angle lens is not easy to use at first to create compelling images, as it’s very easy to include too much clutter in your compositions.

PROS
- optical quality is excellent (deserves an “L” lens designation)
- uses the higher quality ring-type USM focusing
- minimum focusing distance is very close
- surprisingly lightweight
- very flare-resistant even without hood
- the only option for EOS digital cameras (Rebel, Rebel XT, 20D) to get true wide angle shots due to the smaller APS-C sensor in those cameras.

CONS
- It’s expensive! But at least it is cheaper than a year ago.
- The lens is a little soft in the corners at 10mm, but is very sharp at 12mm and up.
- Canon has not formally committed to how long they will continue to make cameras and lenses using the EF-S system.
- The lens currently only works on the lower-end dSLR cameras — the 10D, 1D, 1Ds, and 5D cameras cannot use this lens.
- The hood is not included with this lens, but it’s such as ugly hood and the lens doesn’t have flare problems, so I don’t really think it is necessary anyway.

In 5 years when you upgrade your camera, there is a possibility that it will not support this lens. This depends on what direction Canon goes in making camera sensors:
1) continue to make cameras that use the smaller APS-C sensor, and keep improving its density to support more and more resolution. This will help keep the dSLR cameras smaller and lighter, and will necessitate making EF-S lenses the standard.
2) make the sensors match the size of a frame of 35mm film. And at the same time increase the density to yield even more resolution. Right now sensors this big are very expensive to produce.

I now think that #2 is more likely to happen. All the other lenses out there are built for a 35mm-film-sized sensor, and now that Canon has released another full-frame camera (5D) at a lower price, I’m betting that in another few years the APS-C sensor will be practically obsolete. A 5D body and 16-35 or 17-40 lens will give you better results than a 20D with this lens, but the difference in price between the two setups is a few thousand dollars right now.

The 10-22 is an excellent lens, but it will probably not hold its value as well as the Canon 16-35 and 17-40 lenses. A slightly more affordable alternative is the Sigma 10-20mm, which sounds like it nearly equals the optical quality of this lens.

Canon EF 100mm f/2.8 Macro USM Lens for Canon SLR Cameras

Bring small things into full-sized view with the Canon EF 100mm 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 lens offers such features as a three-group floating system for exceptional close-up performance; a secondary diaphragm that blocks stray light at f/2.8, which increases contrast when shooting wide open; a ultra-sonic monitor (USM) that provides outstanding autofocusing speed at all focusing distances; a wide manual focusing ring with smooth action; and full-time manual focus even in AF mode. The first lens in its class to feature inner focusing, the lens carries a one-year warranty.

• Focal length: 100mm
• Maximum aperture: 1:2.8
• Lens construction: 12 elements in 8 groups
• Diagonal angle of view: 24 degrees
• Focus adjustment: Inner focusing system with USM
• Closest focusing distance: 1 foot (film plane to subject)
• Filter size: 58mm
• Dimensions: 3.1 inches in diameter, 4.7 inches long

• Weight: 21.1 ounces

Canon EF 100mm f/2.8 Macro USM Lens for Canon SLR Cameras Review

The Canon EF 100mm f/2.8 Macro USM lens is an extremely good lens. I spent weeks researching which single lens I should first purchase for my (now extinct) 10D, and this lens won out on three points: sharpness, f/2.8 and 1:1 macro capability. The only thing it’s missing is zoom… and that I can do with my feet.

I have since added a Canon 28-135 to my (small) collection of lenses. The 100 mm macro is not the lens I usually use, except when I am doing studio work of small things… which means that whenever I am working in my studio it’s on my camera except for portraiture.

That’s not to say it isn’t good for portraits; on the contrary, it’s great for portraits. I just have too little room to work with indoors for it to be very useful as a portrait lens.

This lens, however, was touted as being “as sharp as L glass”, and “one of, if not the, the sharpest non-L lenses Canon makes”. I have not yet started purchasing L glass, but I can attest that this lens will make even critical pixel peepers like myself quite happy.

I use two methods for getting exceptional focus. First, I hit the shutter button to achieve focus five separate times. This achieves and fine tunes focus. Second, when I am doing macro work, I always focus manually.

No rails or ring lights here; I’m not a macro photography expert. But I have never failed to appreciate the sharpness this lens offers in all usages.

Another nice thing about it is the small 58 mm filter size. Much easier on the wallet than 72mm, 77mm, 86mm, etc.

I love this lens. The only drawbacks I can find with it are:

1. It is a prime. You have to move it or use rails to get a different “zoom”.
2. It is sharper than is advisable for doing portrait photography. You’ll have to manually “soften” some images to minimize skin blemishes if you don’t want to airbrush.
3. Distance from subject in macro mode is only a handful of inches… not enough for doing macro work of most animate living things.

Otherwise, I always come back to this lens for when I need razor sharp images.

By the way, I find that reviews are not as useful unless I know the experience level of the photographer and their camera type. I am using a Canon 5D Mark 2, which is 21.1 mp. This allows me to be supremely aware of flaws to the optics. This lens keeps up with the full frame 21 mp sensor just fine. I am also what I would call a semi-pro photographer who is on the early end of “medium” level of skill/experience compared to the top pros. I have been studying photography, on my own and in college, since 2000. Hope that helps.
