The MP-E 65mm f/2.8 1-5x Macro Photo from Canon lets you render subjects at up to five times life-size magnification with a minimum focusing distance of 9.4". Dedicated solely to macro applications, this lens's unique design employs a floating elements system to maintain quality throughout the focusing range. One ultra-low dispersion element helps to control color fringing and chromatic aberrations for high clarity and color accuracy. A Super Spectra coating has also been applied to suppress flare and ghosting for more excellent contrast. This 65mm f/2.8 is strictly manual focus operation only and features a removable rotating tripod collar for improved stability when working atop a tripod. Short telephoto prime is designed for full-frame Canon EF-mount DSLRs, however, can also be used with APS-C models where it provides a 104mm equivalent focal length.

Manual focus operation for precise control over focusing distance when working with close-up subjects. One ultra-low dispersion (UD) element greatly reduces chromatic aberrations and color fringing for improved clarity and color accuracy. Six-blade diaphragm contributes to a pleasing out-of-focus quality when using a shallow depth of field. The front ring of the lens supports direct mounting of an optional Macro Twin Lite or Macro Ring Lite and the lens has electric contacts for full support of the E-TTL II flash system and for relaying accurate focus distance information.
