The optical qualities of the lens make it worth carrying the weight along with you. It is sharp throughout the range, has excellent contrast and good neutral colour rendition. With a constant aperture of f/5.6 throughout the focal lengths and excellent performance wide open there is very little to criticise.

In my opinion, this lens is a breakthrough product. In real world situations it will get you many shots that you would miss with the prime and teleconverter system.
