I have no complaint about arf23's post. I notice however that the seller below is half the price and offers a list of supported cameras. The
DSC-W550 is not listed however there are several close matches and they offer:-
"DSC-W390/L
DSC-W560
DSC-W570"
"If you do not see your Cable listed, please ask seller a question, we can point you in the right direction - we are the UK Largest camera cable supplier"
Good luck.
PS
I want nothing to do with Sony or Apple. They both seem to aim to make life difficult for
victims customers.
