These are the .96 orthos. The only better Orthos are the Abbe/ Zeiss and perhaps the Pentax (much more expensive), which are also no longer in production. I have the 6, 10, and 16mm and want $450 for the set. The 1.25 adaptors (I purchaced new from Anacortes) are $15 each. (if you need them with the set).
I also have a New Zess/ Jena Konig 24mm /1.25 barrel available if you want something in that focal range...
(Sale Pending...thx MIlan)
