So the consensus seems to be that the 50 / 80 / 150 kit is popular for good reason. One would choose the 50mm for a distinct wide angle feel (somewhat akin to a 28mm on 135 format) and my thought of the 60 / 150 kit only if I intend to keep within a targeted subject or general purpose subject matter.

I suppose versatility should win out here.

So, say I decide to go for the 50, should I hunt for a C or a CF? If I choose C, both of my existing lenses would match, but if I choose CF, it would benefit me to upgrade the other two lenses as well, which naturally will increase my overall cost, but will potentially be better in the long run due to limited serviceability of the older C lenses. What are your thoughts on this?
