I managed to win an auction for a Schneider-Kreuznach Componon f5.6 80mm enlarging lens. According to the serial number it's from around 1960. I paid $17.95 as the only bidder. It is all chrome. My present lens is a f4.5 75mm S-K Comparon that I bought new as a starving student in 1970. It appears to be black anodized aluminum. 99% of my prints are 8x10 or less and the Comparon does fine. I'm hoping the Componon will be better for the occasional 16x20. I can't remember what I paid for the Comparon. I just know that at the time I couldn't afford the Componon. Allan
