Sometimes all those cool photo tools, don’t end up being as useful as you thought when you bought them. Instead of letting them turn into antiques, get some cash for them that you can turn into more productive uses. Because electronics change so rapidly, they can lose all their value in a few years. OEM Lenses are much more resistant and can often keep their value for a long time. Nonetheless, if you find gear that you haven’t used or touched in year, it is unlikely that you will ever use it.
You can always list your items on Craig’s list, but the pro camera gear often only appeals to a small segment of the population. You might have better luck using one of the online retailers that has a trade-in program. Adorama.com sells new and used gear, and they will also buy your used gear for cash. Simply drop them an email and tell them what you have. They will arrange shipping and cut you a check once they inspect it. Same with KEH.com. This merchant deals with lots of used stuff. Get on their mailing list and you will be notified when they have a representative buying gear at local camera stores or other events in your area. You can also contact them for a quote by email.
Amazon.com has a trade-in program as well. Instead of cash, you receive Amazon gift cards or store credit. If you are an Amazon Prime member or you buy lots of things from Amazon, this could make a lot of sense. They take lots of different items for trade besides photo gear. It doesn’t matter if you purchased it from them or not.
