If you want to use the Maxview 40 with your Coolpix, you'll need one of these. I thought I lost this one in the field, so I bought a second one. Then I found it in my "miscellaneous" case--duh! I don't need two, so this one needs a home.
This step ring fits Nikon 800, 900, 950, 990, 995 & 4500 cameras. Scopetronix sells these for $31 + $8 s/h. How about $24 shipped in ConUS. Paypal(+3%) mo or cash okay. I would also trade for a Rigel Quickfinder.
