For close-up photography there is no substitute for a tripod with a center column that can be swung off-center to get closer to the ground, and a ball head to make positioning the camera fast and easy.

The close-up mode in the Basic Zone can be used with any lens to get close-ups at the lenses' minimum focusing distance. It's no substitute for a macro lens.

When photographing small objects from coins to insects, your lens' focal length and minimum focusing distance affect how small objects are captured in photos. For example, if you're photographing a small coin, you probably don't want it to appear as a tiny coin surrounded by a large background. More likely you'd like a photo showing a large coin surrounded by a small background. For many pictures, just zooming your lens in on the subject will suffice. However, macro lenses allows you to get a lot closer to the subject, making it much larger in the final image. If you can't get close enough to an object to fill the image area, you can always crop out the unwanted areas later. However, the more you crop, the smaller the image will become.

Canon offers a wide range of macro lenses that are compatible with EF Extension Tubes EF12II and EF25II and Macro Ring Lites ML-3 and MR-14EX.

■ Extension fit between the lens and the camera body and allow the lens to focus much closer than normal, giving increased magnification. The larger the amount of extension and the shorter the focal length of the lens used, the greater the increase in magnification. Because of the Digital Rebel's new lens mount, new extension tubes EF12II and EF25II replace the Extension Tubes EF12 and EF25. These are the only extension tubes that work with the EF-S 18-55mm but they also work with almost every available Canon EF lens. Magnification varies, but for standard zoom lenses it is about 0.3 to 0.5 for the Extension Tube EF12II and 0.7 or over for the Extension Tube EF25II.

■ The EF 50mm f/2.5 Compact Macro focuses up to 9.1 inches (231mm) for 1:2 (half life-size) magnification. At 9.1 inches and f/11 depth of field is 0.24 inches (6mm). The EF Life Size Converter for the lens extends its range to between 1:4 and 1:1 magnification and also compensates for spherical aberrations.

■ The EF 100mm f/2.8 Macro USM lens focuses over the full range from infinity down to life size (1:1 reproduction ratio). The lens allows full-time

manual focusing so you can override autofocus whenever you want. When shooting at life size (1x) magnification, the minimum working distance between the lens and the subject is approximately 6 inches (152mm), providing enough room for an additional light source.

■ The EF 180mm f/3.5L MACRO USM Telephoto Lens shoots throughout the focusing distance range from 1x to infinity. The lens has full-time mechanical manual focusing and focuses as close as 1.5ft (0.48m).

■ The manual focus MP-E65mm f/2.8 Macro Photo Lens extends the capabilities of conventional macro lenses and is designed exclusively for high-magnification close-ups from 1x to 5x. Working distances (from the front of the lens to the subject) range from 4 inches at 1x (life size) to 1.6 inches at 5x. The lens is equipped with a detachable tripod collar.

■ Canon's Angle Finder C attaches to the viewfinder eyepiece so you can photograph from a low angle without kneeling or lying down. It's also great when doing copy work and macro photography. It features a rubber eyecup, a built-in adjustable diopter, and a roof prism that keeps the image correctly oriented. The viewfinder has switchable magnification (1.25x or 2.5x). The 1.25x setting shows the entire frame including exposure data outside the picture area, while the 2.5x setting provides a magnified view of the center of the image area—excellent for critical focusing with macro lenses and other specialty optics.
