My wonderful Nikon CoolPix 990 camera was stolen, so I'm selling off some of the accessories I had for it.
Nikon TC-E2 2x telephoto adapter: Doubles the focal length of the built-in camera lens, allowing long telephoto shots and close-ups. Discount price is $135, I'll sell this one like new in every way (used only once before the camera was stolen), including factory soft case and caps, for $89 + shipping (PayPal preferred). This lens fits the CoolPix models 900, 950, and 990, and 995 directly; also fits the 775, 800, 800, 880, and 5000 with a small adapter ring ($10 at Nikon retailers -- I don't have one).
I also have a wide-angle adapter for sale -- see separate ad.
