Porro's are good optically but they are a small part of the market. I predict that since the manufacturers put most of there R&D money into roof's the porro will become extinct just like the dinosaur. I give them 5 years. What do you think?
Porro prisms are the only feasible solution for bins with large objectives, they are the ideal solution for straight birding scopes, and reversed Porros are better suited to close-up work than roofs.
They are still in demand in other areas outside of birding, so obituaries are premature.

A short time ago, (within the past year) you said the Nikon 8x30 EII, (porro) was the best binocular on the face of the earth. :t:
Ditto for the Canon 10x42 IS, also a porro!
I don't see any NEW porro's being developed by any of the big three and to me that signals death. All the new models are roofs. SV's,CL's,FL's and EDG's.
