Sony DSC RX100 - a chip or just a bolt on the lens barrel?

[Salmon81]

Hi,

I have a Sony DSC RX100. 

I've just discovered something on the outer lens barrel.  It can only be seen when the camera is switched on and the lens is extended. It's on the bottom, on the bridge between the 2 pieces. It's round and small and partially hidden because it is on the join.

I worry it's a scratch or chip of some sort. I'm not sure - hopefully it's just a bolt holding the barrel in place. 

I'm just wondering whether anyone else has this, or might know what it is. 

Thank you.

Can you provide a photograph of the chip?  I have a RX100 but cannot find any such issue.

it is the head of a pin used to allow the lens to extend,   Completely normal ...got it on mine!
