At a glance; EF-Mount/Full-Frame Format Aperture Range: f/4 to f/45 One Ultra Low Dispersion Element NANO USM Autofocus System Optical Image Stabilizer Lens Information Display Full-Time Manual Focus Rounded 9-Blade Diaphragm They had this to say about the Canon EF 70-300; Usually you can bank on Canon for delivering some of the best tele lenses across all classes and that also applies to the Canon EF 70-300mm f/4-5.6 USM L IS II. Canon managed to improve the lens in many aspects compared to its predecessor. As far as the optical characstistic is concerned, Canon shifted the priority more to the long end of the zoom range - which is generally a good thing. The image quality doesn't reach professional levels but for a consumer lens, it's certainly impressive with a generally very good quality at 200mm and 300mm. At 70mm the image corners aren't that hot (combined with a bit of field curvature) but from a real-life perspective that's usually a lesser issue. Lateral CAs are very low. Image distortions and vignetting are about typical for such a lens. See the review here..
