FOR SELLERS

Image is everything! Make sure you post as many shots of the lens. Close-up shots are great and tells the buyer exactly what they are getting. More is better here. Don't leave out any dings or scratches because when the buyer finds out later the stuff you didn't mention in the listing, they might send Dispute and then it's just hassle on both parties to take care of all this. When shipping the lens, make sure you send it in dust free environment. If you have the original box and everything, that's no problem, but if you only have the lens, make sure you put the lens in a clean zip lock bag where no moisture or dust can get in. DUST is major problem with camera and lens equipment. Give lots of padding and your buyer will love how you handled the transaction.


FOR BUYERS

Be very careful on listings with no pictures, even if the listing has lots and lots of descriptions. The seller's point of rating the lens might be completely different from retail shops do. Seller might say it's on scale of 9.5 out of 10, or it's in MINT condition... but unless you see it for yourself, a word is just a word. Contact the seller before bidding, and ask them to send you larger picture of the item. Perhaps in different angles. This does serve two purpose. 1. You know the buyer actually has the item on hand. 2. You can judge it yourself and not just their words. Most of all, if bidding goes higher than 75% of the full value, I'd suggest you go buy new lens. Another words, if the lens cost $100 new, do not bid over $75 unless the lens is hard to find on retail shop.
