Canon EF-S 18-200mm f/3.5-5.6 IS Lens

The Canon EF-S 18-200mm f/3.5-5.6 IS is a standard zoom lens. The Canon EF-S 18-200mm features a large circular diammeter lens element that is 72mm in diammeter. The new Canon EF-S 18-200mm f/3.5-5.6 IS is designed specifically for the dimensions of a 'cropped sensor' (1.6x crop) and hence can be made smaller than a 35 mm equivelant lens. 

On an EOS 60D this lens would provide a 29 - 320mm (35mm) equivelant field of view.

The Canon EF-S 18-200mm fits exclusively on those EOS cameras with an EF–S lens mount – the new EOS 60D, EOS 400D, EOS 350D, and earlier EOS 20D and 300D models. The 1.6x multiplication effect of these cameras’ APS-C size sensor gives the lens an effective focal length of approximately 29-320mm.

To improve image clarity over the total image area, Ultra-Low Dispersion glass (UD) elements are employed to eliminate secondary chromatic aberrations that otherwise reduce sharpness and introduce colour fringing. To ensure crisp, high contrast from one corner of the frame to the other, aspherical lens elements have been introduced to avoid spherical aberrations that can soften images, especially at wider apertures. 

In combination with digital EOS CMOS sensor and DIGIC image processor technologies, the Canon EF-S 18-200mm f/3.5-5.6 IS delivers image quality surpassing that required for many commercial applications.

Superb optical quality of the Canon EF-S 18-200mm f/3.5-5.6 IS with an aperture range of f/3.5-5.6 over the full focal length range allows photographers to set exposure at the widest aperture and concentrate on framing, without concern for adjusting shutter speed at longer focal lengths.

The Canon EF-S 18-200mm f/3.5-5.6 IS features Canon’s latest 4-stop Image Stabilizer (IS) for dramatically reduced image blur caused by camera shake. IS significantly extends scope for shooting in low light conditions without flash, or for gaining depth of field. The 4-stop advantage allows a photographer shooting in low light to use a shutter speed of just 1/15 sec instead of 1/125, with no perceptible increase in image blur.

IS automatically detects when the camera is mounted on a tripod, thus preventing feedback loops between the IS sensor and stabilizer motor vibrations.

By optimising Super Spectra lens coatings and lens element shaping, Canon’s engineers have been effective in suppressing flare and ghosting – more prone to occur with digital cameras due to reflection off the image sensor. By increasing light absorption, coatings reduce reflections off lens element surfaces to deliver crisp, undistorted images with natural colour balance.

When used in conjunction with Canon’s range of EX Speedlite flash units and the internal flash of the EOS range, the lens passes distance information to the E-TTL II flash algorithm to improve flash exposure metering.

An optional lens hood, made exclusively for the Canon EF-S 18-200mm f/3.5-5.6 IS, and pouch are available.

In keeping with Canon’s Kyosei philosophy of living in harmony with the environment, the lens features only lead-free glass.

Image Stabilizer works by using gyro sensors and circuitry to detect and measure unwanted vibrations. Tiny servo motors then create 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. Unwanted movement is corrected fast enough to suppress effectively the vibrations of moving vehicles and aircraft such as helicopters.
