You truly have to have your subject centered in the front of the lens and it is easy to misdirect the lens towards your subject. While the front of the lens barrel is 58mm in diameter, the front element is approximately 20mm in diameter (roughly nickel-sized). The short working distances can be frustrating at first and the difficulty is amplified by that small front element. If you want 5:1 magnification, your subject must be 1.6 inches from the lens.
You cannot have 5:1 magnification at a distance of 8 inches. To put it another way: The MP-E65mm will only be in focus at these focal lengths. The working distance of this lens decreases as you progress your way up the magnification ratio, starting at 4 inches at 1:1 and ending up at 1.6 inches at 5:1. The MP-E 65mm’s variable magnification ratio ranges from life-size to five times life-size (5:1). A standard macro lens will have a working distance (the distance from the front element to subject) in the neighborhood of 6-8 inches and a life-size magnification ratio (1:1). Written a review? Contact us and we'll add it to the list.The main reason to use this lens is the MP-E 65mm’s variable magnification ratio and extremely close working distances. Note that other manufacturers may have different ways of displaying such information that may or may not match up with the Canon figures.Ĭanon MP-E 65mm f/2.8 1-5x Macro Photo - reviews and articles Remember that MTF charts are good for comparing similar lenses, so comparing ones from the 14mm f2.8L and 300mm 2.8L won't tell you much at all, whilst comparing the EF14 2.8L with the EF14 2.8L II will show meaningful differences.

If using with flash, at higher magnifications, it is well worth getting one of the special MP-E65 lens hoods/shades (cheaper versions can be found on eBay at a fraction of the full price)īetween x1 and x5 magnification, the lens extends to what seems to be an astonishing degree, compared to any other lens you've likely used. The filter holder ring is grooved on the exterior enabling quick and effective mounting of the MT-24EX dual flash unit and other ring lights.
The viewfinder gets increasingly dark too - this is a lens that needs a lot of practice to use well. Note though that the aperture values are those set via the camera, and not the actual effective values of the optical system, which varies with magnification and are higher.Įffective Aperture = (Aperture Setting) + (Aperture Setting x Magnification)Īt high magnifications and higher aperture settings, loss of sharpness through diffraction can be discerned - however without focus stacking, this may be the only way of getting a usable DOF. You set the magnification and the move the camera or subject to achieve focus.ĭepth of field is very thin, as shown in this table. The design is macro only - there is no focus adjustment. This macro lens is the only one having the MP-E designation in the entire EF range. Launched in 1999, this is very much a 'one of a kind' lens.
