Thank you all.
Being a bottom feeder, always look for value in respect to quality.
I am glad to hear the 150/4 is not a dog as reported in some other posts. I might just win one, one of these days.
I am leaning towards a 45/80/150 setup for my daughter. It is pretty much what I shoot. Slight WA, normal, slight telephoto. It's why I don't have a 600mm plus for my 8x10.
I have found no 'dogs' in the rb67 range and was amazed that any Mamiya lens was classified that way.
Helpful info from all.
