I just got a VERY nice 500c/m with WL and prism finder. An 80mm and 150 mm lenses and an A12 back. I just did a test between this, new to me, camera and my RB67. It takes awesome photos that's for sure!
It is certainly lighter and easier to wield in the field.
The camera with the WL and 80mm lens only weighs 1oz. more than my Nikon D300 with a 16-85mm VR lens.
Hasselblads are built light the glass can get a little heavy,I gotten away with hand holding it using faster shutter speeds . Most of the time use the tripod .
