Macro lenses are the best choice if you plan to do a lot of close-up photography. They attach to the camera in place of the normal lens and need no additional accessories – in effect, they have a built-in extension tube which allows for much closer focusing than normal.
All Canon EF and EF-S Macro lenses (except the MP-E65mm f/2.8 1-5x Macro) will focus to infinity, making them suitable for general subjects, but have an extended focusing range that takes you in close enough to shoot life-size images. These lenses are optimised to give their best performance at close distances, unlike other lenses that give their best results with middle distance subjects. All camera functions operate normally with macro lenses.
It is very easy to produce blurred images when taking close-up pictures. That’s because the magnification not only increases the size of the image, but also any movement. There are two types of movement to overcome – camera and subject.
Camera movement is inevitable if you hold the camera in your hands. Your hands are never perfectly still and pressing the shutter button introduces additional movement. This movement is more noticeable during macro photography than it is during normal photography. The answer is to fix the camera to a solid support, such as a tripod.
Even with the camera on a solid support, slight movement can be introduced as you press the shutter button. To avoid this, use a remote release. Some cameras have a built-in wireless receiver that is activated by the small Canon Remote Control RC-1, RC-5 or RC-6 hand units.
Other cameras have a socket for the cable from a remote switch. If you do not have these remote accessories, then set the timer to a 2-second delay. When you press the shutter button, any movement will have died away before the shutter fires.
