Kim, I'm waiting for bino guru Glen Warchol to weigh-in on these. While I suspect roofs also, there is a configuration called "reverse porro" that could be what we have here, but I'm not familiar enough with it to be sure. Maybe Glen will be able to shed some light on it. Im not familiar with the old Orion Little Giant line, unfortunately. C. --- Kim Hyatt <khyatt@smithlayton.com> wrote:
I noticed in the ad the curious appearance of the 9x63 model (looked like roof prisms to me) but the ad said "porro prisms." Could the 9x63 model be the same Orion used to sell as the "Little Giant" binos? They were a roof prism model - Nate Goodman used to have a pair. 'Way back then, maybe ten years or more, Orion sold them for around $100, I believe.
