Ring Macro Extension Tube for Nikon D3 DSLR D3S camera D3X D90 D3000 D3100 D5000 D5100 D7000 (Electronics)
How to offer for sale of such junk? I tried the rings on my own Nikon D5000: no focus. I become more and more suspicious when I search something on this site (and others for that matter, given the honesty of cyber-merchants).
