EF 75-300mm f/4-5.6 III
• The optical system, construction, and exterior are the same as the EF 75-300mm f/4 – 5.6 III USM’s.
• The difference is that it uses a DC motor instead of a USM to drive the AF.
• Ideal for sports, portraiture, animals, etc.
• The telephoto effect can make the picture look compressed or have excellent background blur.
• At the 300mm focal length, you can fill the frame with a postcard from 4.9' away.
