Canon EF 70-300mm f/4-5.6L IS USM review
Designed to deliver ultra-high quality images along with lightning fast
operation, the new Canon EF 70-300 f/4-5.6L IS USM telephoto zoom lens
brings a favorite zoom range to the celebrated Canon L-series of lenses. It
features two Ultra Low Dispersion (UD) elements for improved image quality
and reduced chromatic aberration, incorporates a floating focusing
mechanism for sharpness from close up to infinity, plus an IS system that
increases usability by approximately four stops. The EF 70-300 f/4-5.6L IS
USM features a function that prevents erroneous operation when the lens is
mounted on a tripod or monopod. Gleaming white, dust and water resistant
construction, and a newly developed Fluorine coating that keeps soiling,
smears and fingerprints to a minimum, its phenomenal performance and
flexibility is assured. For portraiture or to bring what’s far away
up close, this addition to the L-series is guaranteed to perform.Sample
