I purchased this lens because I was tired of using manual focus lenses with adapters. I have recently been to Myanmar with the A7s and a Leica 80-200mm F/4.0 lens. The Leica did produce quite exceptional results, but I experienced a lot of critical focus misses. This is the rub of MF lenses. So, here we are with some initial thoughts on the Sony FE 70-200mm OSS F/4.0 G Lens. The lens is white along the lines of the Canon telephoto lenses. It is a relatively light lens for its focal length range, and so far the AF seems to be quite quick.

We tested this lens on a NEX5n and the results were very very good. I think that it will be even better on the NEX6! This is a small, light zoom that covers the 35-70mm range for full frame. On a NEX crop it becomes 53-100mm equivalent. This lens demonstrates little lateral chromatic abberations, little fall off, and excellent colour contrast. You can expect the famous contax “look” and sharpness. Critical to any adapted lens is the adapter. We used a Kipon type adapter that allows the lens to reach infinity focus at the correct point.
