Noise after power on

[Domink1990]

Does anybody has same problem? Its after power on camera but not everytime, maybe 1 of 30 starts (sounds on). I tried clean contacts on lens and camera. It looks like initial reset operation between camera and lens wasnt completed. Lens is about 3 years old, but works fine except this noise. other lenses on thar camera didnt make this. Thanks for advice

Hi Domink1990,

Can you share the model number of your camera and lens so we can help.

[Domink1990]

Of course, Sony 35 mm 1.8 oss with Sony a6400

So today it happends on another body of a6400. Another lenses doesnt make this, so its sure problem is in that lens. But why only sometimes..for example yesterday it was withou problem all day. I think it related with focusing, cos after this sound, everything works except autofocus. Until restart camera and startup is ok.

Hi Domink1990, try taking out the batteries for couple off minutes and make sure all your equipment are up to date.
