First, I love the Bronica System. David is correct about the Bronica medium format link. EXCELLENT! My MF systems include the S, S2, S2A with lens from 40mm through 500mm and Bronica's ETRSi with AEIII prism and an assortment of lens. This older Bronica system is the real work horse and I believe the S2A is the strongest of the series of bodies.

If the system would be for your daughter. I would recommend the Bronica ETRSi. This is the 645 format and Nick's description of items for sale are good prices. The ETRSi is the newest version of the 645 Bronica format and will enable her to use a flash easier than with the older systems. It can be upgraded to include a prism which has a meter. I find the 150mm would be more a portrait size lens with the 50mm being the wide angle. I typically use my 75mm even though I have the 50mm, 75mm, 100mm, 150mm and 250mm lens for my ETRsi system.
