h.v. I only have experience with the 1968 Autoreflex T and I would say it's build is like the other cameras of the time - robust. Capable of pounding a nail. In fact, when I bought mine from across the country, the seller sent it in a USPS box with no fillers or padding! I received it with no cosmetic flaws and all shutter speeds accurate but I haven't even tried to see if the meter works as it uses the now unavailable mercury batteries. The shutter has a rather long throw like my Chinon CE-II. I really do need to exercise it some more as the only lens I currently have is very good too.
