Despite instructions The installation of the lens is quite a fumbling, especially because the lens came with a guide that was obviously created with an older model of the camera, the inside but differs in the decisive details some of the more modern model. So you can find in the manual two spacers described, actually there are but four. Must remove one two fours, but what of that?
Overall, the objective served its purpose, the image quality suffers slightly (blur in the peripheral regions and in more distant objects). Would I buy a second camera, then I would use the installation service of instar. That was me here definitely too much fumbling, Ausprobiererei, etc.
