The EF 70-200mm f/4L IS USM is a lightweight, compact L Series telephoto zoom lens with Image Stabilizer. The optical Image Stabilization in the new EF 70-200mm f/4L IS USM lens provides up to an incredible four stops of shake correction-a first for Canon IS lenses. The use of fluorite UD lens elements provides excellent optical performance in terms of resolution and contrast. These features, together with its water-and dust-proof construction, provide both the performance and portability to meet user demands.
Take one of Canon’s most popular lenses, the Canon 70-200mm f/4 L, add an up-to-4-stop Image Stabilizer and you get the Canon EF 70-200mm f/4.0 L IS USM Lens. If you don’t need the subject-action-stopping and background-blurring capabilities of the faster Canon EF 70-200 f/2.8 L IS Lens, this lens will deliver everything else you need in a smaller, lighter and less-expensive package.
The Canon EF 70-200mm f/4 USM L IS may well be the very best tele zoom on the market today – it is certainly the best Canon zoom lens tested locally to date. The lens was capable to deliver a near-flawless performance is 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). The only heartbreaking drawback for some is the price tag which increased significantly to a whopping grand – price/performance-wise this is still very sound though.
Just get one, I did and I love it.
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.
