Product Description

From the Manufacturer

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

Product Description

Autofocus lens for macro photography up to life-size (1x) magnification. Inner focusing affords a long working distance of 5.9in. (149mm) at 1x. A 3-group floating system results in excellent delineation at all focusing distances.

Ring USM for silent and high-speed AF, and full-time manual focusing also provided. The optional Tripod Mount Ring (B) B (with adapter) enables the lens to be rotated for vertical or horizontal framing.

5.0 out of 5 stars An excellent lens for the budding nature photographer December 15, 2004

By Scott Burgess

Prospective buyers of a macro lens for a Canon EOS system have a great first choice in this 100mm Macro. The extra length over a 50mm macro gives much better working distance (space between lens and subject) in the field, and EOS-compatible lenses by other manufacturers match poorly with accessories and are nowhere near as sharp.

Compared with the earlier Micro Motor 100mm Macro that Canon made (which I also own), the USM lens focuses *very* fast. The USM lens also can accept Tripod Collar B (by use of a small plastic adapter)--I recommend you buy the collar with the lens, as adjusting to a vertical composition with a tripod means repositioning everything. The front element is not recessed in the USM model, which makes lens cleaning easier than with its predecessor. And build quality is improved--the earlier model was prone to its switches breaking (could fix it yourself with the ordered part, but really annoying) and eventually the Micro Motor gearing gave out (no trouble so far with the USM ring motor). The USM model will work with Canon's 2x teleconverter by interposing a 12mm extension tube, allowing 2x magnification with lots of working distance, though this is not nearly as nice a solution as the 180mm lens referenced below.

I will quibble with another reviewer--Canon does make sharper lenses, and sharpness compared with the earlier model is virtually the same. But this is still one of the sharpest lenses you can buy, and ergonomically a huge improvement over its predecessor.

Having said that, Canon now has an L-series 100mm macro that is a bit sharper and has better bokeh (out-of-focus highlights). A serious hobbyist might consider that lens, though it costs about 40% more on the street. I purchased the Canon EF 180mm f/3.5L Macro Lens less than a year ago, and am very impressed with its greater sharpness and working distance relative to this lens. If you work much with small critters, take a look at that lens before making a purchase.

If you are building up a set of lenses for outdoor/nature photography and you do occasional macrophotography, this might be the first or second lens to buy. If you work significantly at magnifications greater than 1:1, consider the Canon 65mm 1x-5x Macro zoom.

5.0 out of 5 stars An extremely versatile lens. January 7, 2005

By Richard B. Williams

This is the lens I leave on my camera for general purpose use. At non-macro focus distances, it is a very fast lens in a convenient short-telephoto length. The images are sharp out to the corners. This is one of those great Canon lenses that probably deserves an L-series rating but is available without the red stripe and exorbitant cost.

Tested in an astrophotography context (point sources on black backgrounds - excellent for revealing aberration and coma), I have found that this lens is reasonably sharp at f/4 and completely sharp by f/5.6. For daylight terrestrial photography, the tiny aberrations caused by the wide-open f/2.8 aperture are hardy noticeable and by f/4 the images are exquisitely sharp.

There is a lot of glass in this lens - it is heavy. I highly recommend buying the tripod collar as it allows you to attach the camera and lens to a tripod or ballhead with much better balance.

Also, if you plan on using the macro functionality, keep in mind that the effective f-stop of the lens goes way up when you're focusing at very close range. At 15cm from the front surface, it performs as though it were an f/9. You'll either want a lot of light or a very steady subject and a good tripod (another reason to buy the hideously overpriced tripod collar).

5.0 out of 5 stars Sharp, versatile and a bargain January 29, 2006

By G. Clark

The 100 f/2.8 macro is very sharp, even for general shooting, so it works great for portraits, too. When I'm not using a zoom, this is my walkaround lens for people, relatively tight scenes and even indoor sports. Think of it as a great lens that also shoots macro than the other way around. Hard to beat that versatility at the price.

But it comes into its own at close distances. If you've never had a macro lens, you'll run around shooting everything in sight because everything looks new from a macro perspective.

Canon has several macro lenses. I prefer the 100 mm over shorter lenses because I don't have to get quite as close to that bee or wasp. The 180 mm gives you even more distance from your subject, more background blur and amazing sharpness. But it's much more expensive and in most cases you'll need a tripod, and I shoot a lot of improptu macros as I'm hiking.

For extreme closeups with larger-than-life images, there's the MP-E 65. It goes up to 5X, compared to the 100mm's 1X, but you lose autofocus with this lens. In fact, you set your magnification and then move the camera until the object is in focus! As you get beyond about 2X, the viewfinder gets fairly dark. If you're doing still life macro work, it's amazing. I'll probably get one someday for shooting my mineral colletion.

One thing to keep in mind with any macro is that because of the close distances, you're often in lower light conditions. Althought it's fairly pricey, I'm using the MT-24 EX, which lets you adjust the direction of the twin flashes. The MR-14EX ring light is a couple hundred dollars cheaper but will produce a slightly flatter image. And you can always use one of the standard flashes, though the closeness of your subject may cause some odd shadows.
