Two days ago Photoscala tested the Zeiss 24mm f/2.0 lens and was pretty disappointed. They compared the lens with the Nikon and Canon 24mm f/1.4 lenses. The Nikon an Canon lenses were both sharper than the Zeiss. But whcih is the best 24mm lens? Surprise, it’s the cheapest of all of them, the Sigma 24mm f/1.8 EX DG Macro!!! (Click here to read the full test at Photoscala). The user reviews on Amazon (Click here) and BHphoto (Click here) are quite positive. And also SLRgear (Click here) gave the lens a high rating! You can also take a look at a set of image samples on Flickr (Click here). So is the Sigma $549 lens really better than the Zeiss $1,249 lens? What do you think?
