After cleaning effect. Sony a77

[anatolymar]

Hello all!

I have sony a77.  If I take the photo  I see black spots. I go to Sony Center  and they told to me that my sensor APS-C  need to cleaning.  So I did.

When i photograph (with table lamp) i see on the screen yellow-green stripes. (see pictures) It's OK? Or effects of cleaning?

Turned back in Sony center what is it, they said that this is a Moire effect. It` is true?

Thank you for your attention

Thank you

Hi anatolymar

Do the stripes show up on the finished file, ie when you take a photo? Assuming they dont, this banding (actually more like large newton rings than moiré, but no matter) is likely due to smearing on the pellicle mirror.

Perhaps you cleaned the mirror as well as the sensor? They're probably even more delicate than the sensor, very easy to scratch and you should never use cleaning fluid on them.

They aren't horribly expensive to replace, but I'm not sure re-cleaning would be a good idea.

If you explain a little more about your cleaning method I can perhaps help further.

Cheers

This stripes only visible on the screen. I take a photo other cameras.

I think that they have cleaned the mirror and sensor. About processing cleaning they did not say anything. Can they scratch the Sony service center?

Could you tell me about proccessing of clean.Advise? I have not confidence that the service can do this quality.

I didn't realise the service centre had cleaned the camera for you.

If the coloured banding was not there before you had the camera serviced, I would suggest you ask them to clean it again, hopefully returning it to you without the defect.
