The lens as it was delivered then visually convinced immediately. Sticking points are:
- Extremely good sharpness in the focal plane
- An extremely small focal plane. Photographing with this lens is not for ignorant people, you have to necessarily think about the exact point you want to make the focus. Also first and then shake gently focusing is hardly feasible without removing change, man must therefore really take advantage of the number of AF points or focus manually.
- Complete freedom from color fringes even in bokeh. That there in quite a few lenses.
Optical so everything was terrific - here we go to mechanical:
- The focus has loudly scraped when you have the lens held vertically. Both AF and manual focusing thereby ensured for a common "slopes", ie with small focus changes nothing happened until the mechanism has moved audibly and suddenly. For a lens in this price range absolutely unacceptable, therefore this specimen went back to Amazon.
- The second copy was much better. The focus was mostly round, but had at medium distances do a few hangers and was not free from scratching noises. The hangers were especially responsible that the AF has quitiert not focus when small changes in distance, ie without manual intervention could not trigger one. Even that was unacceptable and I doubted already in the AF of the camera.
- Have after a lot of thinking and considering all return the lens I decided to test one copy. And lo and behold, here the AF is perfect and runs completely scratch free.
In this respect, 5 stars for the optics, 5 stars for a working lens, 2 for a bad copy and in turn 5 on Amazon, from wherever fast replacement has arrived.
Addendum to camera Change: At the Nikon D90 does not work, the OS system long as efficiently as eg on the D750. Probably a timing issue, so the D90 already receives, during the Objekti is not yet ready.
