Pinewood: No, although I was prescribed spectacles when I was 12 (and that's over 50 years ago!) I've never worn any. My left eye is poor for close-up, but fine for distance, and my right eye is just the opposite, so they tend to balance each other out, yet I can always see more sharply with my right eye, using binoculars, by adjusting the dioptre. When I was in the ATC (RAF Cadets) I was a marksman with a .303 rifle, using my right eye unaided, even though the target was 'fuzzy'! I'm quasi-ambidextrous: right handed for writing, table tennis, kicking; left handed for bowling, throwing, golf; weird or what? When using binoculars, I prefer to have the eye-cups rolled/turned down and well into my eye sockets, or slightly up if I get occasional 'black-outs' on the edges of vision. The old Nikon 7x35 is just right for my eyes, with the rubbers removed, but the Nikon Action EX needs the rotating eye-cups up a bit. I don't have any problems with eg. the Swift Audubon/Kestrel, or Zeiss Octarem, which is probably why I like them so much.
Henry: Thanks for the Nikon information. Whatever it is (A or E) it's solidly built, and the focus wheel is black-painted brass, just starting to show. Focusing is still super-smooth. It reminds me of the legendary Nikon F SLRs, of which I have two, one chrome with the standard pentaprism, the other black with photomic head. Even the leather case exudes high quality. And like the Swift Audubon, the Nikon 7x35A has that wonderful 3D effect; it may not be as contrasty as the Action EX, but it has a nicer 'you are in there' image. Most of all, it's an 'easy view'. Not very scientific I grant you, but I know what I like... As to the rubber eye-cups, I hadn't realised they just slide on/off; they are so shallow, and clearly not meant to be folded down. On, they limit my field of view; off, I can see the 'big picture'. From the serial number, can anyone advise when the 7x35A was made?
