The Canon EF 70-300mm f / 4-5.6 IS II USM is a mid-range telephoto lens with four-step image stabilization and a new Nano USM motor for fast and quiet autofocus.
It weighs 720g, features a nine-blade diaphragm for attractive background blur, and is equivalent to 112-480mm when used in APS-C sensor bodies.
An interesting idea is the lens’s LCD panel that can be used to cycle through three modes: focal length (shown as 35mm equivalent on crop sensor bodies), a two-dimensional camera shake meter, and The current focus distance is completed with a simple depth of field scale.
Build quality and handling are acceptable for the price, but it lacks a seal around the lens mount.
Overall, though, it’s a great match for Canon’s mid-range DSLRs, offering a good balance of portability and image quality.
