The Sigma 18-200 mm f/3.5-6.3 DC OS HSM II: A new stabilized super-zoom
Sigma announced its 18-200 mm f/3.5-6.3 DC OS HSM II lens at the beginning of October 2011. While there’s not much new in terms of its specs compared to the previous version (the Sigma 18-200mm F3.5-6.3 DC OS —see 18-200mm DxOMark reviews), the publication of its measurement results gives us the chance to take stock of all the Sigma offerings for this lens type.
