Bought this to attach a pair of manual Nikkor lenses (35-70mm f2.8 & 80-200mm f2.8) to a Panasonic GH4. The adaptors secure snugly to both the lens and the camera body with no wobbling or noticeable 'give'. The lenses sit nicely and even the huge 80-200mm feels safe and secure. Images from the lenses with the adapter are excellent.Documentation is a little on the light side - it's possible to put the lens on upside down but that will soon become obvious if you do and it won't lock properly. It's important to twist the silver ring after fitting in order to engage the aperture control ring of the lens. If you're changing the aperture with no effect, this is probably the reason.
