Depends on what your intended usage is. The Schneider Componon S and recent Rodenstocks are good lenses. The 150 mm El Nikkor that I use is sharp as a tack. The El Nikkor will pass UV much better then the Schneider and Rodenstock lenses. I have heard this from two independent sources. Apparently the El Nikkor lens incorporates a different glass and coating then the other lenses. This becomes a consideration if you decide at some point to buy the 4X5 Azo enlarger lamp that is being brought to market.
