150mm Sironar S or N

[El Topo]

Thanks everybody for the answers. It seems that the Sironar S is going to live to up to its reputation, so I think I'll go for it.

Matus, I think I prefer to stick to Rodenstock (my other 2 lenses are also R), but thanks for the advice

Having a digital back, i'm not using 4x5 enought, i will reduce my number of lens...
