The MP-E65mm f/2.8 1-5x Macro Photo is a photographic lens that was released in September 1999 and is 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 EF50mm f/2.5 Compact Macro and the EF-S60mm f/2.8 Macro USM, 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 natively. It is capable of generating full-frame images up to ten times the size of the subject with the addition of a 2‌× Extender teleconverter. Minor additional magnification can also be achieved by the addition of a Canon or third-party extension tube. It exhibits an extremely low depth of field, a maximum of 2.24mm at f/16 at 1× magnification, and a minimum of 0.048 mm at f/2.8 at 5× 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[citation needed]:

Effective f-number = f-number × (magnification + 1)

For example, at 3× magnification with a listed aperture of f/8, the effective f-number is 8 × (3+1) = f/32. Hence, the lens may have an effective f-number of f/5.6 at 1× magnification to f/96 at 5× magnification. When a Canon Extender EF is attached, the usual f-number compensation is applied (in the previous example of f/5.6 at 5× magnification, the effective f-number would be f/180 if the Canon Extender 2× was attached to the lens.) Magnification is continuous, not discrete, so fractional magnification values (for example, 2.3×) are possible. The lens circuitry communicates the chosen magnification ratio to the , so it will be recorded in the image metadata. It can be viewed by Exiftool version 8.11 or later.

Canon recommends using either aperture priority or manual mode when using this lens.[1]
