to the EF 28-70mm f/2.8L USM, but with a wider zoom range to meet the needs of photographers using certain digital cameras.The EF 28-70mm f/2.8L USM has proven very popular with professional and advanced amateur photographers since it was introduced in 1995. However, the increasing use of digital cameras, most having sensors smaller than a 35mm film frame, has increased the demand for a high-performance standard zoom lens with a wider wide-angle setting. The EF 24-70mm f/2.8L USM lens meets this need. The optical design is based on the previous lens, but incorporates new design features that allow the broader focal length range while maintaining the superb image quality. At the same time, the minimum focusing distance has been reduced from 0.5 metres to 0.38 metres.Improved water and dust resistance ensure that it will become the leading standard zoom lens in the EOS system.FeaturesHigh-speed AF Optimized lens coatings Highly resistant to dust and water droplets Min. focusing distance of 0.38m at all focal lengths Front of lens does not rotate during focusing Manual focus is possible in AF mode Only lead-free glass is used
length lens. It has four UD-glass elements to correct chromatic aberrations. Newly-designed multiple zoom group inner focusing brings high image quality throughout the zooming range. Compatible with Extender EF 1.4x and 2x.

features the very finest in L-series lens optics to deliver stand out optical performance and operability.The professional?s lightweight IS telephoto zoom.4-stop ISThe EF 70-200mm f/4L IS USM features the world's first 4-stop Image Stabilizer (IS). Ideal for handheld work, the exceptionally accurate and sensitive IS negates the need for a tripod in many conditions. Shutter speeds up to 4 stops slower than would be otherwise possible (e.g. 1/15 sec instead of 1/200) can be used with no perceptible increase in image blur. For stabilised panning, IS Mode 2 corrects only for unwanted vertical shake.L-series qualityThe lens embodies Canon?s highest standards of L-series optics, build quality, reliability and operability. Crisp, high contrast image quality is assured right across the frame and throughout the entire zoom range. A reliable partner in tough conditions, the metal and polycarbonate construction features special environmental seals to prevent the ingress of dust and moisture.LightweightWith a length of just 172mm and weighing only 760g, the EF 70-200mm f/4L IS USM is ideal for assignments where there is a need to travel light without compromising performance, operability or image quality. Fixed apertureWith no change in aperture over the full focal length range, photographers can set exposure at the widest aperture and zoom through to 200mm without slowing shutter speed. Lens length remains constant during zooming and focusing. Fluorite and UD lens elementsThe lens incorporates a single Fluorite and two UD (ultra-low dispersion glass) lens elements to suppress secondary chromatic aberrations. The result is crisp, high contrast, undistorted images throughout the entire zoom range, without colour fringing at subject outlines.Auto focusA Ring-type USM (Ultrasonic motor) delivers responsive, high-speed, silent auto focus. Holding torque is excellent, stopping the focus lens group with precision and without overshoot. Full time manual focus override is available without switching out of AF. Minimum focus distance is 1.2m throughout the zoom range.Super Spectra coatingsOptimised Super Spectra coatings and lens element shaping suppress flare and ghosting. Coatings also help achieve true colour balance and increase contrast.Pleasing background blurThe Electro Magnetic Diaphragm (EMD) features an almost perfectly circular aperture to create an even and attractive blur from out-of-focus backgrounds.AccessoriesA cylindrical bayonet hood and soft case are included.FeaturesL-series optics Light and compact 4-stop Image Stabilizer f/4 through zoom range Fluorite and UD lens elements Fast auto focus Environmental seals Super Spectra coatings Circular aperture for pleasing background blur Soft case and lens hood
performance for all general purposes. The compactness and lightweigth make it an excellent travel compagnon.High-performance, L-series telephoto zoom lens combining light weight and compactness with an f/4 maximum apertureHigh-performance, L-series telephoto zoom lens combining light weight and compactness with an f/4 maximum aperture. Inner focusing and the ring USM enable quick and quiet autofocusing. Also, a circular polarizing filter can be attached and used without difficulty because the front lens element does not rotate during focusing. The tripod collar (sold separately) is the same one used with the EF 300mm f/4L USM.FeaturesLens construction: 16 elements in 13 groups Diagonal angle of view: 34°-12° Focus adjustment: USM Closest focusing distance: 1.2m Filter size: 67mm

Overview
-------------
I bought the EF 17-40 f4 L about 3 years ago in order to take urban landcape pictures, as buildings often don't fit into a 28mm "frame". This optic is the widest in the f4 constant aperture series of zoom lenses in the trio that more
When I bought my Canon EOS 20D, I was thinking about getting a cheaper Sigma or Tamron objective to go with it. But since the optical performance of those 3rd party can't keep up with the Canon ones most of the time, because of the reverse-engineered... more
