Review on Canon EF 70-300mm f/4-5.6 IS USM Lens - Optimized for Canon EOS SLR Cameras by Kio Proviax ᠌

I am satisfied with the lens, if you choose between it and the 70-200L F4, then definitely 70-300 is a stub and a larger zoom. Fast and nimble, gives a beautiful picture and nice bokeh. There is a possibility of a little blurring at 300, but if the hands are strong and get used to it, then no problem. Got pros: Nimble, stabilizer, good bokeh, quality, zoom, not noisy. Cons below: loud motor, aperture, to fully fold you need to switch to MF mode
