As a young teen, I had what can only be called LUST for the Beseler Topcon Super D, the world's first commercial SLR with TTL metering, a pro grade beast with the rugged durability of the Nikon F (but with TTL metering built in). Now, over 45 years later, I have managed to acquire FOUR of these cameras (all with serial numbers of the original version Super D the 4xxx, not the later version 7xxx built in the late 60's/early 70's, as well as one of its smaller brothers the Beseler Topcon D-1. I ran film thru all five bodies, to check the shutter speed accuracy...and all five are perfectly accurate throughout the speed range, with zero evidence of slow shutter speed or inconsistency. Thirty-seven years ago, I bought an Olympus OM-1, and I still have that body. And its shutter speeds are accurate, too. Six purely mechanically timed shutter cameras, all accurate. One would think that lubricants in all six bodies would, by now, gum things up. I cannot account for the tested accuracy in spite of lubricant-gumming time...except for the fact that there was no lubricant! My (owned for all this time) 47 year old Beseler Topcon Auto 100, made for the amateur market and having leaf shutter, does have shutter timing issues.
