EF 75-300mm f/4-5.6 III
For roughly a few buck less than the EF 75-300mm f/4-5.6 III USM the EF 75-300mm f/4-5.6 III offers everything that the former does except feature a DC motor instead of micro-motor USM. The lens is optimized for the larger image circle of full frame Canon DSLRs. It is ideal for wildlife and sports photography but will require a tripod to stabilize.
The optical system" construction" and exterior are the same as the EF 75-300 mm f/4-5.6 III USMs. The difference is that it uses a DC motor instead of a USM to drive the AF.
