hi Lofty, there is nothing wrong with filing a dispute to say there is a problem, have you filled out the feedback yet? did you ask the seller before the sale if it would fit your camera body? You could inform that the advert was misleading and send the item back, Paypal are very fair with this as no one would want to buy something that does not fit. It is felt that the seller omitted to say specifically which lens it would not fit and mislead by informing that it fitted most digital cameras. If it is a business seller then you have a right to return the item WITHOUT question under the distance selling Act, within 7 days. Have included details below. best wishes,
There are three pieces of legislation relevant :-
(a) Distance Selling Regulations, this allows you to send goods back and obtain a refund for any reason within seven working days of delivery. However, you have to pay for the return of the goods. There are more details here :-

(b) Sale of Goods Act, this allows you to obtain a full refund if the goods are not fit for purpose. There are more details here :-

(c) Consumer Credit Act, this means, if the retailer is disreputable and wrongly refuses to refund you, your credit card company may refund you and then they will recover the money from the retailer's bankers. There are more details here :-
