I would advise as follows:
Hasselblad 501C for the gliding mirror if you want to use anything longer than 100mm, and if you get the 500CM, get the acute matte screen
- Distagon 60/3.5 CF or CB
- Makro Planar 120/4 CF or CB(I think there were a few in the CB version)
-period (think of the 35/75 combo in 35mm).
The 60 is a fantastic landscape and environmental purpose lens, while the MP is one of the best lenses in the Hassy line for portraiture and close up - but stopped down to f 11 -16 it can do also landscape or architecture. For a longer portrait lens, I would recommend the 150 Sonnar, as it is less clinical in its rendering.
Avoid lenses earlier than CF or CB for spare parts availability reason.
