Camera/lens problem

[brianp55]

Hi, I have a 7d mk2 /efs 17-55 mm lens. I keep getting a error up about contacts need cleaning, I have tried other lens on and they work ok. So I believe the problem is the lens, I have tried cleaning the contacts carefully with glass lens cleaner but it made no difference, anyone have an idea what I could try please. Cheers Brian.

Contacts may not clean well with lens cleaning fluid it might take a proper contact solvent cleaner ... some people use a pencil eraser but if you do be careful not to let the rubbings contaminate the equipment.

A pencil eraser/rubber can work well. Just hold the lens upright so the debris falls away from it.
