Canon EF 70-200mm f/4 L IS USM Lens for Canon Digital SLR Cameras |
| Product DescriptionCanon EF 70-200mm f/4L IS USM lens offers the highest possible optical quality with no change in aperture over the full focal range of the lens. This allows photographers to set exposure at the widest aperture and zoom all the way through to 200mm without having to decrease shutter speed. Developed for use with a Canon SLR camera, this autofocus telephoto zoom lens offers optimized use with the Canon EOS series digital cameras. Of particular note, Canon has introduced an image stabilizer (IS) that adjusts to meet the demands of professional photography. IS reduces dramatically the image blur caused by camera shake. Gyro sensors detect unwanted vibrations, triggering the corresponding movement of a correcting lens group perpendicular to the optical axis. This alters the light path, returning the image to its correct position on the sensor or film plane. For shooting immobile subjects, Mode 1 corrects for movement in the image along both the horizontal and vertical axes. For shooting while panning horizontally to follow a moving subject, Mode 2 turns off vertical correction and prevents the effect of dragging the subject back through the frame. The lens' Ring-type USM employs ultra-sonic frequency vibrations to drive auto focus with unrivalled speed and near-silent operation. A powerful CPU and improved AF algorithm contribute to speed performance. The EF 70-200mm f/4L IS USM includes distance metering information, providing compatibility with the E-TTL II flash system of late model cameras such as the EOS-1D Mark II, EOS-1Ds Mark II, EOS 5D and EOS 400D. When used in conjunction with Canon's range of EX Speedlite flash units, the lens passes distance information to the flash algorithm for markedly improved flash exposure metering. Includes Lens hood and soft pouchAmazon.com Product DescriptionCapture the far-off action of fast-paced sports or zoom in for an intimate portrait with the Canon EF 70-200mm telephoto zoom lens. The L-series lens offers an Image Stabilizer that provides up to four stops of shake correction--a first for Canon IS lenses. The use of fluorite UD lens elements, meanwhile, produces an excellent optical performance in terms of resolution and contrast. Add in a sturdy housing with water- and dust-proof construction and you have a lens that's both portable and high performing. Other details include an f/4 maximum aperture, a ring-type ultra-sonic monitor (USM) that enables quick and quiet autofocusing, compatibility with circular polarizing filters, and a lightweight body. The lens carries a one-year warranty. - Focal length: 70-200mm

ReviewsThis is so far the best lens I have used and I was speechless to look at the quality of pics it produced with my 5D mark II
I will learn to take more pics with it
So I bought one of these on Amazon earlier in the year, and was truly impressed with the build and picture quality. They say it's the sharpest of the 70-200mm family, and while I have no comparison, I am hard-pressed to know how the 2.8 IS could be better other than the obvious bigger aperture. Definitely worth it over the non-IS version if you plan to do any handheld. Because of the long focal length, you can actually REALLY see the stabilization at work when you start to focus. The zoom length is a good compromise for the size, as the 2.8 is HUGE and would require a completely different type of camera bag.
My dad actually borrowed this lens for a vacation and had his whole camera kit stolen, and I immediately purchased another one. That's how amazing this lens is.
In the first few pictures taken, this lens has already surpassed my expectations. It's image quality is better than all of the other lenses that I currently own and is extremely sharp.
The IS more than makes up for the extra cost, especially on the upper end. It's nice not to have to carry a tripod around for most events.
I bought this lens as a replacement for the Canon EF 70-300mm f/4-5.6 IS because I wanted something better built that did not extend and focused faster. That was what I told myself, I really wanted to buy it because it was an L lens! It did all the things mentioned but after comparing the pictures I took side by side, I decided it was not worth the premium. It did not help that my copy had some IS issues. The pictures were great, focus in low light was a tad better than the 70-300 and it locked on smaller objects faster than the 70-300 in good light. If the non, extending barrel, non-rotating front, marginally faster focus and better build are worth the extra money to you this is an awesome lens. For me it is my least used lens so the premium was not worth it especially since the image quality was marginally better. I give it 4 stars for image quality and ding it one star for price/value.
It is the best lens I ever had. The image stabilizer is really good and obtains a great definition. 100% recommendable for anyone. It is better to pay a little bit more by an original product.
