A bit noisy and certainly not good for video but works fine. This model is specifically designed for APS-C sensors (a6000, NEX-5N, etc.) so it will vignette when using a full-frame camera (A7r, etc.). Focus unlike other A-mount adapters on the E-mount and I'm very happy with it - it struggles for focus from time to time but I think it may just be the lens installed. In most cases it's very quick to focus in my experience and I could even use it for sports and wedding photography, although it wouldn't be my first choice for a wedding due to the noise level. it does.
