The new lens offers an extended zoom range at the wide-angle end and incorporates an Image Stabilizer (IS), which compensates for approximately three shutter speeds, allowing the handheld capture of shots that would otherwise be blurred by camera shake. The EF28-300mm f/3.5-5.6L IS USM delivers high-contrast, high-resolution images for which Canon's L-series is renowned. A combination of advanced optical technologies, including UD (ultra-low dispersion) and aspherical lenses, work in concert to achieve a high zoom ratio of approximately 11x while effectively correcting for a variety of aberrations that can occur when zooming. Featuring a new optical design, the lens makes possible a minimum focusing distance of just 0.7 meters throughout the entire zoom range. Other features include a circular diaphragm for improved background blur, and a hardy waterand dust-resistant construction, ensuring professional users unfailing performance under even the most grueling of conditions. And, in consideration of the environment, the model uses only lead-free glass elements.
Amazon.com Product Description
Canon raises the stakes for professional photography with its EF 28-300mm USM ultra-high magnification zoom lens with image stabilization. This handy, compact zoom lens offers versatility, easy subject selection, and the highest optical performance in its class. The 11x zoom range covering everything from wide-angle to telephoto, and you can focus in on subjects as close as 2.3 feet. A powerful ring-type USM drive provides silent. Featuring a dust- and moisture-proof "white lens," it is designed to appeal to professional EOS photographers looking to reduce lens changes and the number of lenses they need to carry.
Image Stabilization
The lens incorporates Canon's Image Stabilization (IS) technology, compensating for approximately three stops without any perceptible increase in image blur when shooting static subjects or panning. This increases the range of circumstances in which hand-held photography is possible, limiting the need to carry a tripod.
Fast Auto-Focus
The inner focusing ring-type ultrasonic motor (USM) converts ultrasonic vibrational energy into rotational force to deliver high-speed, high-precision, super efficient and virtually noiseless auto focusing, with good holding torque for rapid response, accurate stopping. Full-time manual override without damage to the autofocus mechanism is featured. Minimum focusing distance is just 0.7m throughout the entire zoom range.
Ready for Digital Photography
The lens shape and coatings have been optimized to suppress ghosting and flaring, making this lens ideal for use with digital cameras that are more susceptible to reflections off the recording media than are film cameras.
Precision Optics
This lens features 22 elements in 16 groups for low distortion, high corner-to-corner resolution throughout the entire zoom range. As with all EF lenses, aperture is controlled with an EMD (electromagnetic diaphragm) for fast, quiet, highly precise control and incorporates a circular aperture diaphragm for beautifully pleasing background blur, from full aperture to two stops down.
The use of 3 Ultra-low Dispersion (UD) glass elements effectively curtails the residual chromatic aberrations that can plague lesser quality long lenses, while aspherical elements correct various kinds of aberration that occur during zooming to give the lens the unsurpassed clarity and resolving power that are the hallmark of professional L-series lenses.
Environmental protection
The EF 28-300mm f/3.5-5.6L IS USM features a rugged dust-proof and drip-proof construction, designed for professional photographers working in harsh environments under a wide range of operating temperatures and humidities.

Canon EF 28-300mm f/3.5-5.6L IS USM Lens Reviews
| 374 of 376 people found the following review helpful  Nice piece of glass., By Amazon Verified Purchase This review is from: Canon EF 28-300mm f/3.5-5.6L IS USM Lens (Camera) I was salivating for this lens for four months and finally bought one a few weeks ago from the Amazon. I was very excited and couldn't wait to put this glass on my 20D.First impression I got was that this lens is not that heavy as 3.7 pounds may seem, but boy I was wrong about that. It feels solidly built and looks not that huge on the body. So there we go... After filling up my 1GB CF with shots (taken outside, inside with external flash and without, with different f-stops and all range of zooms) and closely examining the results I decided to write this review with which I did not try to downplay the qualities of this piece of art, just to share my humble opinion. Pros: All in one solution (well may be except super wide) Under most light conditions the lens performs as expected which is very good Great zoom range that converts to 45-460mm on APS-C bodies Nice color saturation and contrast, gorgeous bokeh Push pull zoom (for some may not)...

(major) My biggest complaint is it's consistently soft at 28mm and f/3.5. Too soft for my taste. The shots look "dreamy". I often forget to zoom out a little or drop the aperture when shooting wide angle and end up disappointed in the results. I've seen it on the 20D, 5D2, and 7D so it's not the camera. It's a bummer because the wide angle is often what I want on a crop factor camera. [2] Weight. (major) Your arm will probably hurt after shooting for a few hours, especially with its push/pull it gets long so your arm is extended holding all that weight. There hasn't been a person yet I let try the lens that didn't immediately say "wow, that's heavy". I read that in the reviews and thought "na, I can handle it". Nope. I must admit I had to take breaks. It's painful to shoot video with extended arms as... Read more 111 of 120 people found the following review helpful Fast, clear, heavy performer, By This review is from: Canon EF 28-300mm f/3.5-5.6L IS USM Lens (Camera) I bought this lens for my EOS 20D. Before this lens, I was using EOS 28-135mm lens. After the upgrade, I found that 28-300mm lens give me almost distortion free image even at 300mm range. When I used 28-135mm lens, the distortion on the image is very visible when I am at 135mm range. Even at the wide angle range, I noticed that 28-300mm lens gives me much sharper image while 28-135mm lens gives me much softer image. The focus is very fast for 28-300mm L lens. On the down side, this 28-300mm lens is really heavy. Holding it will really wear you out. The auto/manual focus switch is arranged in a very awkard position. It is very easy to change your auto foucs setting to manual setting. The lens also will be pulled all the way down due to its weight when you carry it around. I have to carry it with my hand and not make it extend itself all the way down. If picture quality is what you are after, go for this lens. I am very pleased with the sharpness and the fast focusing. |
