Canon 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 Canons 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 pouch
Customer Reviews
My favorite lens
I highly recommend this lens. It surprised me when it arrived that its so small and light Im comparing to the EF 24-70 f2.8 L and the EF 300 f4 L. It internally focuses so there is no change in length throughout the zoom range. Its extremely sharp wide open - Ive used it both for close-ups with an extension tube and for more distant shots. Got my first decent close-up of a hummingbird. The IS works so well its hard to distinguish from shots on the tripod - it really does give you an extra stop or two hand-holding the camera. This is pretty much state of the art in lens design. If youre looking for a lens in this range go for it You wont be disappointed.
Canon 70-200mm f4 L IS USM Lens
The Canon 70-200mm f4 L IS USM is a great lens. Its pricey but it provides great quality images. The lens is part of Canons L line up which is a better built product. The lens is light-weight and provides a nice zoom lentgh to get you much closer to the subject you are shooting. The IS works very well. With the greatest aperture value of f4 it isnt the best in low light but that is not one of my concerns it shoots great outdoors or indoors with enough light. The IS helps out some here also. Its the biggest lens I have owned but it still fits nice in a camera bag and isnt too heavy to carry around with other lenses. The only thing I wish this lens came with was a tripod mount. I mounted the camera and lens on a tripod connected to the camera however and it held up fine. It is light enough it will not bow the whole set up down but I wouldnt suggest long use like this. I highly recommend this lens for any Canon DSLR.
Great Lens
I spent a lot of time doing research trying to decide which zoom lens to get and decided to spend the extra money for this one and the results have been well worth it very fastaccurate auto-focus IS works very well Image quality is superb. This has been regarded as one of Canons best lenses. Im using it with my 30D
