bought the adapter to use my old, analog treasures from my Minolta Dynax 7000i on my new Panasonic Luminx DMC-G6. However, because I have already bought several lenses for the G6 and do not use the old ones that often, I opted for a cheap adapter, but also tested the expensive one. In terms of quality, it is unbeatable in terms of price-performance ratio. The lens sits very firmly on the adapter without wobbling and the adapter also sits firmly in the bayonet of the camera. For lenses that cannot set the aperture directly on the lens, I use the "relax without lens" mode on the camera and set the camera so that it finds the exposure time and ISO value itself, thus creating "satisfactory photos" with an open opening. The difference in quality with the more expensive adapters is really very small and anyone who buys a VW Golf does not expect a BMW 7 Series. So if you are looking for a suitable solution to reuse your old lenses for little money, then you have come to the right place. I can only recommend the adapter to everyone, I would buy it again. I hope everyone who decides to buy enjoys, the KF products are of much higher quality than the price suggests. Shipping from China was also fast and easy and my questions were answered quickly by the service. I am very satisfied and will probably buy more camera accessories from the seller in the future.
