I finally wound up with a Watameter, but in all honesty, hardly ever use it. The other hazard with accessory rangefinders is some are marked in meters and some in feet, the same with cameras. So it's nice to get matching units."
Exactly this happened to me, I bought a Voigtlander rangefinder at a price so high, even years later I refuse to admit to its exact cost. It reads in meters and my Perkeo I in feet. Oi! Said RF now resides somewhere in one of my (too) many unused gear boxes. Someday someone will find it and (maybe) use it. I lives in hope...
...most commonly found RFs would be approximately "period correct"
Thank you for this. As one who learned how to do hyperfocal calculations as a young'un (not quite a toddler, but well, you know) and uses same with all my 'period' cameras (even Rolleiflexes and a Rolleicord), I am now formally branded as a quaint and amusing period-piece, alas! not unlike our best known export from Oz to the world, the dinosaurous Uncle Rupie M and his, here in Australia, widely despised print media crap products.
