The MP-E 65mm Macro f/2.8 is a photographic lens manufactured by Canon for use on the EOS photographic system. It is a manual focus lens for the EF mount and is specifically designed for macro photography. Unlike other macro lenses, such as the Canon 50mm f/2.5 Compact Macro and the Canon EF-S 60mm f/2.8 Macro, it does not focus to infinity and cannot be used for conventional photography.
This lens is capable of generating full frame images up to five times the size of the subject. It exhibits an extremely low depth of field, a maximum of 2.24mm at f/16 at 1x magnification, and a minimum of 0.048mm at f/2.8 at 5x magnification. It is sensitive to faint vibrations, with slight breezes or imperceptible movements having potentially significant effects on image focus. A tripod is generally required when using this lens, but handheld photography with this lens can produce images with good focus when a flash is used.
The technical specifications indicate an aperture range of f/2.8 to f/16, which is the value displayed by the camera body when the focus is set to infinity. However, the MP-E 65mm lens cannot be set to infinity,[1] so its effective f-number depends on the magnification ratio chosen, and is calculated as:
Effective f-number = f-number x (magnification + 1)
For example, at 3x magnification with a listed aperture of f/8, the effective f-number is 8 x (3+1) = f/32. Hence, the lens may have an effective f-number of f/5.6 at 1x magnification to f/96 at 5x magnification. Magnification is continuous, not discrete, so fractional magnification values (for example, 2.3x) are possible. The lens circuitry does not communicate the chosen magnification ratio to the camera body, so it will not be recorded in the image metadata.
Canon recommends using either aperture priority or manual mode when using this lens.[1]
