The lens has a threaded filter diameter of 62 mm. We tested the lens with a 6mm B+W MRC Circular Polarizer with no vignetting evident at the 10mm setting.
Sony’s reported weight is 8oz (225g), I am going to assume that this number is without caps, hood, etc… My scale shows this, and I call this bag weight:
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.
Check out this link on UV filters. After a blurb on UV light and its effects, they test the best and score them according to UV ray reduction. One thing that they don’t test is durability… UV Filter Test
This is a superb lens! You can expect extraordinary sharpness right from wide open. Smooth Bokeh and no, and I say again, no chromatic aberrations. The lens distinguishes itself by having excellent separation of the subject from the background, it’s very 3D. Colour contrast is high and images need very little processing when coming from dng files. The lens has a very special look, especially at mid-distances. Close up performance is also very good, due to the floating element. Close up images still retain interesting bokeh as well. Check out the parrot shot below. Vignetting also serves to enhance image quality ( I know that some will disagree), but I really like this lens and its output.
