Sigma 20-40mm f/2.8 EX DG Aspherical Reviews

Ephotozine reviews the Sigma 20-40mm f/2.8 EX DG Aspherical and writes;
“There’s no doubt that image quality is slightly better from the camera manufacturers own brand pro spec lenses, but only marginally, and definitely not enough to justify paying twice as much for a lens, so this new offering from Sigma should be given serious consideration by the professional.”

Sigma 20-40mm f/2.8 EX DG Aspherical User Reviews

Excellent focal length range. | Rating: ★★★★★
“The range is limited to 2:1, so the optical quality is amazing. It’s not like using one of those 5:1 zooms that comes with a melange of distortions and optical quirks. This is like having an excellent “variable prime” at your disposal..” – by Robert R. Jackson
