What a great lens this is! High performance, light weight and easy to handle the 400mm f5.6 L USM delivers super fast auto focus in a super zoom.
This high-performance lens was designed with portability and handling ease in mind. One super UD-glass element and one UD-glass element deliver the shooter crisp sharp pictures from corner-to corner even when opened wide
It is compatible with the EF 1.4x II or EF 2x II tele extenders to effectively double the length of the lens. It accepts 77mm filters, and has a built-in removable tripod collar so mounting your lens to take the weight is an option and certainly something you would want to consider in low light.
Good: Lightweight compared to other super zooms. Compatible with Canon’s lens extenders for even more versatility. Good in low light – though you will need a tripod.
Bad: No built in image stabilisation, so be sure to use a tripod to prevent camera shake.
