Sold a 2nd hand EF 24-105mm L IS lens on Amazon under "Used - Good" category as although the lens has had a fair amount of use over 4 years the glass is unmarked and zoom function is smooth.
The buyer requested a refund however complaining that the focusing made too much of a noise and therefore he regarded it as defective. Later some more detail was added to an official complaint saying this noise occurred when manually focusing.
I had used that lens fairly recently before selling and yes there is a slight sound when the auto focus and image stabiliser kicks in under silent conditions (that is normal right?!) but there is no way that is noticeable or distracting under normal shooting conditions.
I am particularly curious about him specifying the noise under manual focusing as I must admit it is not something i really did much of if ever.
Could there be a defect that manifests itself as noise when manually focusing and not during auto focus? Seems a bit strange to be honest.
