It made me feel like zoom for several years. Coupled with a Sony Alpha 350, I find ideal (equivalent to 28-300 in terms of focus). It can cover all uses, from wide angle to long tele, at an unbeatable price (182) !!! It is lightweight and works perfectly with the autofocus of the camera. Specialized testing crediting the high marks in terms of technical qualities of photography (vignetting, distortion, sharpness, ...). It is lightweight and compact for indoor focal range. In short it is the ideal lens that allows the camera to exit without taking the case of objectives being sure to succeed his photos. Price found in the amazon's great cannon, offering more than 50% reduction from many vendors (including ebay) ... To meditate.
