Canon EF 100mm f/2.8 Macro - Canon EF Mount

The Canon EF 100mm f/2.8 Macro is a dedicated telephoto macro lens offering a 1:1 reproduction ratio. It is designed for the EF mount and is compatible with both full-frame and APS-C DSLRs. The lens is known for its sharpness and flat field of focus, making it ideal for both clinical macro work and traditional portraiture. It features a focus limiter switch to reduce hunting when working at specific distance ranges. On the used market, this earlier non-USM version is often evaluated for the smoothness of its autofocus motor, which is louder than modern ultrasonic drives. SDS verifies that the manual focus ring engages correctly and that there is no 'creep' in the barrel. We also inspect the internal optics for dust, which can become prominent when stopped down for macro photography, and check that the electronics communicate correctly with modern EOS bodies.
