Comments about Nikon Nikon Diopter -5.0 for many Nikon Digital SLR's Cameras:
Nikon does not supply a Rubber Eyecup for this item. And the standard D300 Eyecup is not usuable with the Nikon Diopters even though the Diopter has what looks like the channel cut into it. The standard eyecup is just a tiny bit too small to fit around it Just a bad design from Nikon.
