I'm aware that Nikon 995 is able to focus as close as 2cm when it comes to macro. I have already taken alot of nice shots with the camera, but I just want to get a good macro shot without getting too close to the object. That would explain why I want to buy the closeup lens. Anyway, the general closeup lens is not very expensive. The only thing here is, 28mm closeup lens is rare and more costly as compared to bigger ring size. It is however not impossible to find though. If I'm not wrong, Nikonos is using 28mm filter too.
