Sigma’s 18-250mm f3.5-6.3 DC OS HSM zoom won praise for its balance of performance and convenience, but it looked bulky after rival Tamron introduced the diminutive 18-270mm F/3.5-6.3 Di II VC PZD. Reducing the size, and weight while updating the optical construction to allow a new minimum focus distance of 35cm, the 18-250mm F3.5-6.3 DC MACRO OS HSM is Sigma’s response. But has the redesign compromised the optical performance, or is it a valuable addition to the range? Read on to discover our verdict.
With it true 1:1 macro reproduction and its floating auto-focus system for high optical quality on its very broad range of focus, this Sigma macro lens looks like ideal for a wide variety of photographers, from nature to sport and portraits.
