Canon 50d Vs 7d
This is the lightest EF lens of all at a mere 4.6 oz. (130g). Compact and high-performance, standard lens. Its Gaussian optics provide sharp delineation from near to far focusing distances. The color balance is excellent for a standard lens.
Bring your photographic subjects closer with this Canon EF-S 55-250mm f/4-5.6 IS Image Stabilizer Telephoto Zoom Lens. It is designed with Canon's Optical Image Stabilizer technology and is compact and light. This high zoom ratio lens is equivalent to a focal length of 88-400mm in the 35mm format (when used on Canon EOS cameras compatible with EF-S lenses). The image stabilizer effect is equivalent to a shutter speed about 4 stops faster than the same size lens without Image Stabilizer. In other words, if the slowest shutter speed you could formerly hold a 250mm lens steadily was 1/250th of a second, with Canon's 4-stop stabilization correction, you could hand-hold at shutter speeds as slow as 1/15th of a second. It also uses a UD-glass lens element to correct chromatic aberration for excellent image quality throughout the zoom range. Filter Size - 58mm Max.
