Japanese adapter maker Rayqual has announced a series of adapters for Micro Four Thirds and Sony E-mount with built-in tripod mounts. The adapters allow the use of long and heavy lenses on mirrorless cameras without the camera having to bear the weight. Adapters are available for Nikon F, M42, Leica R, Olympus OM, Canon FD and Pentax K mounts. Aperture control is not available on the F and K mount versions.
