It delivered pretty decent results in most aspects, specifically at 70mm and 200mm, but at 300mm the border resolution is nothing short of dismal - certainly not apochromatic as claimed by Sigma (nor would we really expect that from such a budget lens). Nonetheless you may argue that the center performance of the lens is on a very high level throughout the range and for many tele applications your main subject is often located close to the center so the border problems may not be all that obvious in the real life. As such it still remains an interesting budget solution. If you prefer a sharp border to border quality look elsewhere though ... and prepare yourself to invest quite a bit more. ]]> Mon, 08 Mar 2010 19:38:34 +0100
