So I have around 450 feedback on ebay and 100% positive. Buy and sell my fair share of camera gear and electronics and take a little pride in my feedback. Well, I sold my G3 kit to help cover my D600 purchase, including the 14-42mm kit lens. I usually offer returns but only if found to be not as described (no buyer's remorse). First time ever I get a message saying that there is something wrong with the lens - this was the message (the important part anyway) - It is quite stiff to zoom and something is loose and rattling around in it. If you shake it it rattles. It is not supposed to do this, of that I am sure since I have owned other camera with this lens. The camera seems to work fine. They initially want a full refund, and initiate an ebay case within 12 hours of sending this message (which was sent at 7pm on a friday for some additional context). So, I basically can't use paypal for the week while this is being dealt with (ok, that was the rant section, done with that!). After filing the case Saturday morning we messaged back and forth and came to an agreement to just return the lens for a partial refund, however since I accepted the case resolution to be a full refund upon return, it doesn't give me a partial refund option. I also couldn't refund the money because it was held in my paypal account (I did have about $100 in there prior to the case opening and would've had the funds to cover the partial amount we settled on). So, I get the lens today (more on that in the next paragraph), and have to call ebay to have them change the case from full refund to partial refund. I'm on the phone for a half hour, they eventually say it will be resolved in a few minutes and to watch my account. Sure enough it was resolved....only the message I get is they refunded the $80, released all of the money held in paypal and require no further action from me...essentially they refunded the buyer and aren't asking for repayment - is this just a hidden policy that they charge off to make both the buyer and me (the seller) happy since I've otherwise had a perfect track record? Second question - I've owned many, many lenses of varying build quality and values over that last 6-7 years - most of them make some sort of rattle or shake or some noise or another if you shake it (be it a spring, a lever, a ring or any other number of things) - I looked over the 14-42 they returned, and it is perfect looking, no sign of wear or abuse, the zoom is the same as previous panasonic 14-42mm kit lenses I've owned (that is to say somewhat plasticky and cheap). It zooms fine, takes photos perfectly fine at multiple apertures. It does have a little rattle going on when shaken though - so, to any 14-42mm owners out there - is that normal? Or is it possible they just didn't want the kit lens in the first place? I can't imagine hatching such an elaborate scheme to get out of my 'no buyer's remorse' return clause!
