EF 100mm f/2.8 Macro USM

Many EOS shooters consider this two professional lenses in one: a superior- performance portrait-length tele with a fast f/2.8 aperture and lightning-quick USM AF; and a superb macro lens that focuses to life-size (1x) without accessories. It has a unique internal focusing design and floating optics for sharpness throughout its vast focus range, and allows a working distance of 5.9 inches (149mm) at life-size. Full- time manual focusing and an available Tripod Mount B with adapter round out this terrific macro lens.

EF 180mm f/3.5L Macro USM

One of the sharpest lenses in the entire EOS system, and a brilliant all-around telephoto lens that can focus to true life-size (1x) — with a working distance of almost 10 inches (0.25m) from the subject! Three UD-glass elements, a floating optical system, and internal focusing assure superb performance at any distance. It’s even compatible with the EF 1.4x II and 2x II tele extenders. A powerful ring-type USM means fast and silent AF, along with full-time manual focus. It includes a tripod collar and detachable lens hood.

About Macro Magnification
A life-size macro lens—that is, a 1x
magnification records an image on film
at its actual size. If you’re photographing
a flower, for example, and it has a
diameter of 1 in., it will occupy 1 in. on
your film. Other macro lenses have
lower or higher magnifications. A lens
with 0.5x magnification would produce
an image on film that is half the size of	0.25x
the actual subject. Your 1 in. flower,
then, would only occupy 0.5 in. on film.
In the other direction, a 5x magnification
lens would convert the 1 in. flower to a
5 in. diameter image. Since the entire
image wouldn’t fit in the frame of your
film, you would have an enlarged image
of a detail of the flower. Magnification
is not the same thing as focal length. A
50mm lens and a 135mm might both	0.5x
be macro lenses with, for example,
1.0x magnification. The advantage of
the longer lens is that it allows greater
distance from a subject. You would
choose the 135mm macro lens to
photograph a butterfly or a bird.
The 50mm lens would be more suitable
for a subject that won’t move away
when you approach it.

Extension tubes are one method of getting closer with EF lenses. A powerful tool when attached to standard and wide-angle lenses, they’re also used with telephotos to get just a bit closer. With any lens, the longer the extension tube, the greater the close-up effect. The 12mm EF 12 II is often used with wide-angle lenses, while the longer EF 25 II is a better choice for normal or telephoto lenses. Auto exposure continues to work reliably, but manual focus is recommended in most instances. The version II extension tubes are also compatible with EF-S 18-55mm f/3.5-5.6.

An effective close-up method with telephoto lenses, and the only close-up accessory that doesn’t lose light. The 250D is optimized for lenses between 50 and 135mm, while the 500D works best with lenses from 75mm through 300mm. Both have a double-element design, so their optical quality is excellent. The Close-up lens 500, a single-element design, offers an even more affordable alternative.
