Ricoh has released firmware updates for its K-3 and K-50 DSLRs which add support for the company's K-AF4 lenses. K-AF4 lenses electromagnetically control aperture rather than using a mechanical linkage to the camera body. At time of publication, only the 55-300mm F4.5-6.3 ED PLM WR RE uses this system. The firmware also improves overall camera stability. Download K-3 firmware update 1.30 Download K-50 firmware update 1.10
