Hi, I've been lurking around this forum taking it in, not quite sure my cameras fit, but now I think I have one that does! I went to a car boot at the weekend and scored this Konica Eye plus an Oly tip for £10... Will get a roll through it over the next few days and post a couple of shots. I have no idea if it works fully and didn't know it was half frame, I just liked the look. I suspect that the aperture is slow but like a number of aspects of the design with it's fast lens and I'm liking the original strap. One nice thing is that as well as the shutter speed the viewfinder has a marker for the focus distance, reflecting the one on the lens.
