This telephoto zoom lens provides a large f/4 aperture at all focal lengths. The new multi layer lens coating and lens design reduce flare and ghosting while maintains minimal light-fall-off; superior peripheral brightness is ensured. New multi layer coating of this lens gives superb color performance while cutting down flare and ghosting caused by reflections from the digital image sensor. High optical performance is demonstrated throughout the entire zoom range. Two SLD glass elements are used in the front lens group and two in the rear lens group for superior correction of several aberrations for superior image quality throughout the entire zoom range. An inner focusing system eliminates front lens rotation, making the lens particularly suitable for using the petal-type lens hood supplied and circular polarizing filters. Maximum Magnification - 1 - 5 Filter Size - Diameter 82mm Dimensions - Diameter 92.4mm X Length 226.5mm, 3.6 x 8.9 inch Weight - 51 ounces
This lens replaced a Canon 300mm F4 L IS lens that I just got but returned due being completely out of center. Now, the Canon should be a great lens when properly aligned, but it left a bad taste (and this is not the only Canon L lens I bought that was not in good alignment) and prompted me to look elsewhere. There really are not a lot of options for 300mm and F4 (and I don't want to spend thousands more for an - admittedly - stellar F2.8 lens) and I stumbled on this zoom lens. Usually, I don't go for zoom as I prefer better image quality over versatility. But the used one from amazon warehouse deals was a good price and worth a try.
Heat lens but gets pretty soft wide-open at the long end. Great build/construction.
I bought this lens to use with my Canon 30D for high school sports (soccer, football, baseball, etc). I already had the
Sigma APO 70-200mm f/2.8 EX DG HSM Lens for Canon Digital SLR Cameras
and needed more focal length. Like the 70-200 F/2.8, this lens is big, heavy, and built like a tank. The bare lens is about an inch longer than the 70-200, but the 100-300's hood is longer than the 70-200's hood.
I bought this lens over three years ago, it is probably my most used lens for birds and wildlife, super fast HSM, extremely sharp images, short focusing distance which allows it to be used as a semi macro lens. I have the Canon 70-200 L non is version and find that Lens is regulated mostly to portrait shots when distance is a necessity. Cons if any is the size and weight but no so heavy that it can not be handheld.
perfecto algo pesado pero perfecto
High build quality, sturdy, easy to use. Excellent picture quality. Works great for sports, wildlift, mood photos of people in an urban setting.
I bought this lens because the Canon 100-400mm was alittle to much for my pocket book. I have had the lens over 5 months and used it mostly outdoors with a monopod. A monopod is a must, Living next to Yellowstone Park I use this lens alot, however it is alittle heavy, and needs alot of light to get a perfect picture. Its not a L lens but it has its qualities that are very close, this lens doesn't get the attention it deserves for outdoor photography.
