The Sony 10-18mm or SEL1018 is a fairly large high quality zoom lens for the Sony NEX E mount system. The lens is a constant F/4.0 throughout the zoom range. The lens ships with caps, a petal shaped hood, box and a one year warranty in most juristrictions. It is compatible with all Sony NEX Cameras.

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.
