Sigma SD15

A well-built DSLR camera for photographers who want to work with raw files to obtain maximum image quality.It’s taken a while for Sigma’s SD15 to reach the market. First displayed at Photokina 2008 and then officially announced as a successor to the SD14 on 20 February, 2010, the SD15 has only just gone on sale locally. It offers a few updates to its predecessor but features the same Foveon X3 sensor, which has a focal length crop factor of 1.7x.
