This is a posting on behalf on my good friend. He is trying to sell off his Olympus OM4 with quite a number of quality Zuiko lenses (mainly prime and macro lenses) and accessories like Zuiko telescopic auto extension tube (bellows) to change over to DSLR. What is the good way to sell off the system besides posting in classifieds? Are there any places locally that offer trade-ins?
Thank you for advice.
