mm f2.5 Compact Macro
Here’s an entry-level macro lens that will perform beautifully as it opens up the world of closeup imagery for you. Capable of one halflife-size magnification and 1:1 ratio with the Lifesize Converter EF, this inexpensive and lightweight little lens also functions as a lens of normal perspective that you could use for everyday snapshot photography. This lens is best for inanimate objects, as you have to move in pretty close to get a tight image, a position some creatures feel uncomfortable with. Still, it can work well with people. Many medical and legal operations and investigators use this lens for the everyday documentation of injuries or evidence.
