It's tempting to buy a Tele Mirror Lens for under 200. Unfortunately, the qualities can not convince me really. Focus point must be searched with a lot of sensitivity, which designed to be difficult. The imaging performance are not bad, but my serious demands on quality not sufficient to use the photos for example, in the print media. With a smaller Zuiko lens, the image quality is still better than with this Walimex even with an enlarged under certain circumstances.
