Kamera wechselt AF UND MF im Millisekundentakt?
Hallo,
Ich habe mir gestern das SIGMA 17-50mm F2.8 EX DC OS für meine Nikon D5300 gekauft. Jedoch funktioniert der Autofokus nicht. Dauerhaft wechselt er zwischen AF und MF im Millisekunden Takt. Manchmal funktioniert er für paar Minuten einwandfrei. Woran könnte das liegen?

Ask if you can get a rental optics during the reperature, then the rental optics packerl comes with the optics. For Nikon DX there are mW only 17-70, 18-35 and 18-200.
May be Sigma also wants to adjust the camera (at Canon this is common).
Electronics does not last forever, on average 8-10 years with consumers and 15-20 years with professional technology. But this usually requires a regular (professional) service depending on the operating hours between year and every 5-6 years. When an optics is cancelled, time is also for the last/final end service where you “review the optics”. Because after the end of the production you will have 2-3 years before the spare parts are finished or consumer optics have 2-3 years of legal spare parts follow-up time, professional optics usually have 6 years of legal follow-up time outside “production means” or optics with MilSpec G there are 12 years. Apart from the customer agrees a longer period of use. That’s why Nikon can repair 40-year-old optics even if it’s becoming a mistake expensive. Where 40 years old Nikkor are still without cheap Electronic and the standard chips are still available today for prices in the cent range. Will say that’s easy. At the moment, the 2000s zooms with protective gas filling in the lens group are unrepairable, which can/do not make Nikon, Minolta/Sony/Zeiss or Olympus.
If it is only with the objective, it will be defective or have contact problems. Used bought and not tried? Well, otherwise exchange or give for repair
Yes bought used. In the beginning, it worked super on the seller’s camera. Then I took it in the hope that it might be a problem with the firmware. Once I had, the AF did not go
The seller said it? Or did you see it yourself? Well, bought as sightseeing, I guess. Just clean the contacts. Vlt helps. However, it is more likely that a wobble contact at the switch or in the connecting cable is internal. Can theoretically even have actually been broken only with you and it was absolute coincidence that it occurs now and not before.
Which is also very strange. I can’t hold buttons as soon as the lens is on it. Z.b if I want to take a closer look at a picture and zoom in.
if your camera with other objective has no focus problems, then that is objectively defective. The flex cables usually suffer from zoom lenses when they are pressed or kinked about 20,000 times.
