-Prime 25mm f/2.8 is designed for full-frame Canon EF-mount DSLR cameras, however can also be used with APS-C models where it provides a 40mm equivalent focal length.
-Specifically developed for macro photography, this lens is designed for use within a 2.5:1 to 5:1 magnification range for producing greater-than-life-size imagery. This lens does not offer infinity focus.
-When at 5:1 magnification, the lens has a minimum focusing distance of 6.8″ along with a working distance of 1.6″, which affords sufficient room for illuminating your subject. At the 2.5:1 position, a minimum focusing distance of 9.2″ is possible along with a working distance of 1.8″.
-Wide-angle design benefits the high magnification design by providing greater depth of field compared to telephoto or long lens designs.
-Manual focus operation for precise control over focusing distance when working with close-up subjects.
One extra-low dispersion element greatly reduces chromatic aberrations and color fringing for improved clarity and color accuracy.
-Eight-blade diaphragm contributes to a pleasing out of focus quality when using shallow depth of field.
-Especially slim and lightweight physical design is easier to use handheld and offers more room for illuminating close-up subjects.
