18-135 with high zoom ratio of 7.5 times the high magnification standard zoom lens, the focal length conversion of 35mm specifications can cover 29-216mm focal lengths, optimized lens position and coating can effectively inhibit the ghost and glare generation. The recent focus distance of 0.45 meters, with a strong hand shake compensation agencies, to meet the general needs from photography to macro photography.

Caliber 72mm, lens sturdy, and 50D and other large fuselage is very match; can be equipped with IS, you can get white IS and white contrast, the price difference of 4K; EF-S, for APS-C frame covers a wide angle, very practical.
