I'm upgrading the lens on my Meopta. Can afford either a Rodenstock Rodagon 50mm f2.8 or a Schneider Componon-S 50mm. Both about the same price second-hand. Which would you choose and why?
Both are excellent. The Componon-S is marginally sharper in the corners at f8-11. The Rodagon is arguably better built. I'd go Componon-S if sharpness is the priority.
