Product Highlights: EF-s mount lens. 88-400mm The range of the aperture is f/4-32 Lens elements are with ultra low dispersion. Provided by optical image stabilization. The constant minimum focus distance is 3.6’ Zoom ring is made up of rubber. Beautiful circular diaphragm. Filter thread diameter is 58mm. This lens is manufactured by Canon and the it is lightweight and compact telephoto zoom lens that is specifically designed for EOS DSLR cameras those are using EFS lens mount with APS-C sized sensor. This lens provides high image quality and powerful performance where the offered focal length is 35mm which is equivalent to the 88-400mm. This kind of focal length is ideal for the photographers those are looking for affordable autofocus lens for using in general purpose photography. This EF-S 55-250mm f/4-5.6 IS II lens is incorporating with 4 stop image stabilization technology. This technology allows the photographer to use the shutter speed about 4 time slower without increasing any image blur. One of the other feature is that panning detection is automatically turns off the image stabilizer when you are following any kind of moving subjects. The ultra low dispersion of the lens element can minimize the aberration and it also contributes in sharp and high contrast imaging. Image Stabilization: Previously image stabilization did not work for low light options but now it is extended to those levels. The images taken while holding the camera in hands in the low light and long focal length would have a lot of benefits of 4 stop shutters speed and optical image stabilization system. Superior image quality: There is one Ultra low dispersion element that is used for decreasing the secondary chromatic aberrations, sharp and some other high contrast images without any kind of fringing throughout the whole zoom range.
