Super Range

A large percentage of the mirrorless camera market is controlled by amateurs and enthusiasts who often prefer to have one all-in-one lens rather than several lenses.

Their needs were served by several companies that made 24-200 mm and 28-200 mm zooms. Sony was the only one to have a 24-240 mm lens in its arsenal. Tamron, very recently, launched its own 25-200 mm in the market. Sigma has now launched the 20-200 mm f 3.5/ 6.3 lens making it the widest travel zoom in the market. The Sigma is for full frame cameras and is currently available with either Sony's E mount or Panasonic's L mount. A 10 X zoom very often requires compromises. How good is the Sigma? Read on.

Design & Build Quality

The lens is very much Sigma - well finished but understated in appearance. It weighs only 540g which is light considering its focal range. Polycarbonate has been used in the construction but the mount is made of stainless steel and there are rubber gaskets around the lens mount. The lens is weather sealed but not image stabilised. Dimensions are 77.2 x 117.5 mm. The lens, like all Sigma lenses, is made in Japan.
