I've come across a Steinheil orthostigmat 35, f4.5 - 39 LTM. It says Steinheil München US zone. Probably made in the 50s. There's a specific viewfinder that comes with it. Anyone familiar with that company and maybe this lens? Worth buying (perfect condition, would go for € 150)? Thanks for any comments! JM Jean-Michel Mertz 68750 - Bergheim
