I don't see the point in using an SLR that doesn't have DoF preview, that's the point of having an SLR for me, other wise just use a Rangefinder... lol, and street shooting is good with an RF because of the dark areas where you need to hand hold at 1/30 or 1/15 which you can't do with an SLR
With a Hasselblad the Zeiss lenses are so sharp wide open, there is not need to bother stopping down.
Warning!! Handling a Hasselblad can be harmful to your financial well being!
Nothing beats a great piece of glass!
I leave the digital work for the urologists and proctologists.
