The Canon EF 50mm f/2.5 compact macro lens is lightweight and compact for general-purpose standard focal length shooting and for close-up 1:2 half-life size macro photography. A floating optical system enables sharp delineation at all focusing distances. With a large f/2.5 maximum aperture, the lens is effective in low light and provides shallow depth of field and its truly circular 6-blade diaphragm offers beautiful background blur.
From the Manufacturer
Want to bring small things into full-sized view? Turn to the Canon EF 50mm f/2.5 compact macro lens, which can uncover detail that would otherwise be impossible to detect by the naked eye. Ideal for shooting extremely minute subjects such as insects or the petals of a small flower, the lens offers a nine-element design and a floating optical system that focuses down from infinity to one-half life size (0.5x). Despite these macro optics, however, the lens also functions beautifully as a general-purpose normal lens. And should you want to focus down to life size (1:1), you can add an optional Life Size Converter EF to increase the working distance--a valuable feature in close-up shooting. Other details include a 46-degree diagonal angle of view, a 0.8-foot close focusing distance, and a one-year warranty.
