From a compact prime we go to a giant prime, the Sony 500mm f4G SSM SLR lens which challenged the Dxomark testing process enough that they had to use their new Seattle-dpreview lab in order to get it done. This is their report.
Superzoom time but with restrictions! Photo Club Alpha checks out the Alpha version of the Tamron 18-270mm Di-II lens. Because Alpha DSLRs include sensor-shift stabilization, Tamron did not include optical stabilization (VC) in the Alpha version of the lens, turning what would have been a double advantage into a disadvantage.
