Outer diameter of the glass is too large to get deep enough in the Nikon finder. But, I now know what the optical formula is, of the SBOOI, and likewise, the Nikon finder. So elegantly simple. Hint - it is a 1:1 finder. Not a lens. A simple plano cylinder. The silvered face is lensed, to image the brightline at infinity; so to retain the plano cylinder, a matching lens, but reversed with identical curvature, is cemented on the mirrored surface. Simple. I now need someone who can cut a few millimeters off the rear plano face of the SBOOI middle lens, and re-polish it flat. Piece of cake, right? ....Vick On 1/12/2011 8:52 AM, Vick Ko wrote: > Got the chrome one apart.
