Today (26 Nov 08), I am finding reduced prices and free shipping on the Sigma 17-70 f/2.8-4.5 and the 18-50 f/2.8. One retailer citing a rebate from Sigma. When a retailer offers free shipping, this is often because they are overstocked or the manufacturer is replacing/update the model. Likewise for the rebate.
Does anyone know of new lenses similar to the 17-70 & 18-50 coming out soon?
