Thanks to all for your feedback. This is great.
One more question if you don't mind.
Can you easily use a Hasselblad 501c/m with an 80mm and 150mm lens for candid shots of children?
When/why would you choose to use a MF over a 35mm camera for candid baby, children's, ... wedding photography?
I don't shoot formal portraits much, more the candid stuff.
