Canon EF 70-200mm f/4L USM Telephoto Zoom Lens Description

W
hile it's true that this
zoom lens will never "grow up to be" the f/2.8 70-200, at half the weight and half the cost, it's worth it if you're looking at
hauling around your camera for hours on end.
Canon has created a harmony of features making it the all purpose middle of the line
L lens that is almost as affordable as the 70-300 IS, yet with the weather-proofing, durable build, optical performance, and tack sharpness close to the 70-200 f/2.8.

This is a high-performance, L-series
telephoto zoom lens combining light weight and compactness with an f/4 maximum aperture. Inner focusing and the ring
USM enable quick and quiet
autofocusing. Also, a circular polarizing
filter can be attached and used without difficulty because the front lens element does not rotate during focusing. The tripod collar (sold separately) is the same one used with the EF 300mm f/4L USM.
If you need a
low light lens, this isn't it. If your primary objective is to take pictures in
available light situations such as
weddings and
concerts, then get the
70-200mm IS f/2.8 or the 70-200mm f/2.8 instead.
Like all L
series lenses, this one is built extremely solid. It may feel fairly large and bulky to those who haven't used L series lenses before. The extra bulk is
comes from higher quality glass and the use of more durable materials (metal vs. plastic).
