Canon MP-E 65mm f/2.8 1-5x Macro

A unique manual-focus lens designed exclusively for macro shooting, between life-size (1x) and 5x life-size - at its maximum magnification, you can fill a 35mm frame with a grain of rice. Compatible with the Macro Ring Lites and new Macro Twin Lite, it eliminates the need for awkward bellows accessories for many macro shooters. A floating system preserves optical quality at different focusing distances, and features a UD-glass element.
