The Canon EF 100-millimeter f/2.8 Macro UltraSonic Motor Lens can be used for a multitude of shots, but it specializes in close-up photography. If you have ever wanted to get a photo of an ant or a small leaf, this is the lens you want to purchase. This lens is a fixed 100-millimeter lens, so it does not have any zoom capabilities, which can make using it for portraits difficult if you are a beginner. Standing away from your portrait subject at a distance will ensure your image will be very sharp, but with the 2.8 aperture, you will need patience since it is slow. The EF 100-millimeter f/2.8 Macro lens has an autofocus feature, which some say is a little slow, but once the autofocus finds its focal point, it is extremely precise and clear. This lens does not have image stabilization, but it is not a necessity when using macro focusing distances. Also, due to internal focus, the macro lens does not change length when it is focused.
The EF 100-millimeter f/2.8 Macro lens works well in low light environments, and has beautiful color and contrast with no chromatic aberrations and has minimal distortion. It is a heavier lens than most, but this can be solved by bringing along a tripod or a strap. Whether you are taking photos of jewelry, nature, or people, this macro lens will always deliver a sharp as a tack image.
