SQF results were Excellent at all three tested focal lengths -- a big improvement over the pretty good non-IS version. Good distortion control, too, with Slight barrel distortion (0.18%) seen at 70mm, Slight pincushion (0.20%) at both 135mm and at 200mm (0.29%). Light falloff was gone by f/4.5 at 70mm, by f/6.3 at 135mm, and by f/5.6 at 200mm.

The Canon 70-200mm f/4 L IS is as perfect a zoom lens as I have ever used, and its ergonomics are also first-rate, never getting in the way of a great photograph. I wish all telephoto zooms focused more closely, to about 1.5' (0.5m) instead of 4' (1.2m), but no similar high performance zoom does any better.

The lens was capable to deliver a near-flawless performance in all categories. The resolution figures are stunning regardless of the setting. Distortions, vignetting and CAs are nothing to worry about. The build quality is excellent with the new sealing as a another highlight. On top of that the lens now features a image stabilizer with an efficiency equivalent to 4 f-stops (at cost of shutter speed).

For many, many other general-purpose tele-zoom needs, the Canon EF 70-200mm f/4.0 L IS USM Lens will be a great solution. For shooting at the park (public park, ball park, water park, ...) the beach, the vacation rental house, or just out in the back yard, this is a great lens to have in the kit.
