Canon EF 70-300mm f/4-5.6 IS USM review
The EF 70-300mm f/4-5.6 IS USM telephoto zoom lens has been developed to
meet the high-performance standards that today’s photographers
demand. Improved Image Stabilizer Technology provides up to three stops of
"shake" correction, and the "Mode 2" option stabilizes
images while panning with a moving subject. Compared to the original Canon
EF 75-300mm IS zoom lens, this telephoto lens has faster autofocus, and
overall the lens is lighter and has a smaller diameter than the original.
The zoom ring can be locked at the 70mm position, making this powerful lens
easy to transport, too.
