For my Sony A77 I bought this adapter. I have high-quality lenses Niko recognized by this adapter to the camera and am very unhappy with the photos. The picture quality is bad! The pictures are very blurred!
Although the adapter seems to be really worked well and he also sits safely and accurately, but it seems the lens of very poor quality to be; it feels like plastic and was very difficult to clean even before the first use. The protective sticker on the lens to fog had settled on the lens.
I can not recommend this product.
