They can be found under the wide rubber-turning handle from 150 to 500. One can this broad Grummistulpe simply press to the side and removed with a Phillips screwdriver Watchmaker the Schaube. Then the distance setting goes a little further. The lens itself has a M42 thread that would fit for age-old cameras. For modern cameras each suitable adapter is included. This rather broad Adapter vergößert the distance between lens and camera considerably. That might be the reason why you get sharp images at unveränderterm lens at great distances. Other lenses are designed in such etwar generous construction, so that they do not require changes. The bezel of the actual activation of the set with another rotating ring orifice is also somewhat annoying. With modern digital cameras that is not really necessary. The manual focus is thanks to the slim design very easily. On a scale can be easily seen as in the good old days, what depth of field creates each aperture setting. I highly recommend this lens for amateur photographers very frugal.
