The Canon EF-S 60mm f/2.8 USM macro is a fairly recent addition (2005) to the Canon lens line-up.
The EF-S naming refers to Short-back focus design featuring a protruding rear
element which requires a special mirror design to avoid a collision of mirror and the rear part
of the lens. The principal idea is to reduce the distance of lens to the sensor plane which
can translate to a better lens design thus a better performance. These lenses are compatible
to APS-C EOS DSLRs only.
The build quality is very good based on a metal mount and an outer barrel made of high quality plastics.
The broad, rubberized focus ring and has smooth, pleasant action. A barrel-shaped hood is available
as an option. The lens features a "true" IF (internal focus) design so the front element does not
rotate and the length of the lens remains constant regardless of the chosen focus distance.
The AF speed is very fast which is unusual for a macro lens. Typical for ring-type USM lenses full-time
manual override is always possible in one-shot AF mode. The minimal focus distance is 0.2m (90mm working
distance) resulting in a max. magnification of 1:1. This is an improvement over the classic (full-frame)
EF 50mm f/2.5 macro which requires an additional macro converter to reach this level of magnification.
