Micro lenses are commonly mounted on the tops of the light-gathering portion of pixels (aka photons) and are often angled along the edges of camera sensors to capture and redirect light back into the pixel, as a method of reducing light falloff on the edges of the image and redirecting it for image processing. Not to be confused with NIKKOR micro lenses.

Canon Lens Class and Technology Abbreviations - this autofocus motor is smaller and simpler than USM used in most Canon lenses. Like its big brother, it is fast and quiet when used in smaller lenses with lighter optical elements. There is a disadvantage, though Micro USM does not generally allow full-time manual focus override. There are exceptions. One notable lens to feature the simpler Micro USM motor rather than full-sized ring-type USM yet allow full-time manual focus tweaking is the Canon EF 50mm f/1.4 USM. Both USM and Micro USM motors are indicated as USM on the lens itself.
