<ul> <li>Front side - MFT female mount</li> <li>Rear side - CS-mount (1"-32tpi thread)</li> </ul> <p>Machined of high quality aluminium alloy.</p> <p>This adapter allows mounting MFT lenses onto cameras with CS-mount. Infinity focus is provided, but no the lens should work in fully manual mode.</p> <p>Also take note that this adapter is for CS-mount, not C-mount. These threads are same, but flange focal distance is different. If you install it onto C-mount camera, infinity focus will be impossible, and you will be able to focus to close distances only.</p>
