The technical data of the Zuiko Auto-Zoom are not spectacular: 100-200mm, biggest aperture 1:5, a minimal distance of 2m are not stunning. On the other side the lens has a built-in shade, it is light and handy and can be equipped with filters in the standard Olympus 49mm diameter. The most spectacular thing is the increase of the lenses length. The upper picture shows the lens set to infinty with the shade slided in, in the lower picture it is set to the nearest distance an the shade slided out.
