I bought the Alpha 7R to adapt my Leica lenses. This is thanks to the digital viewfinder, the Focus Peeking and a zoom function brings, very possible. By light amplification also focusing in a dark environment without any problems. The picture quality is with lenses such as the Leica APO-Summicron R 2 / 90mm or the legendary Summicron R 2/50 outstanding. The resolution is breathtaking. Negative I find the very short battery life. Here one can not avoid a second battery. All in all, a very good successful overall concept.
