Roger: What kind of quality are you getting now? I have found the Schneider convertable to be good lenses when used at their prime focal length. I don't see where you would get a noticable improvement, but there will probably be someone who will take exception. Shooting in low light, which is softer, you will not get the contrast and apparent sharpness you will get in bright sun. However, for scenics, the slightly wider angle of the 135 may be of benefit. It depends upon what type of scenic you are shooting. I would keep the convertable, as it can make acceptable negatives at its converted length in a pinch, especially when filtered. Both the Schneider and Rodenstock are good lenses and both are the plasmat formula.
