Tried it in a Verizon store. Even though it was well lit, the stupid thing took 3-5 seconds to focus, and shutter speed was extremely slow (1 second) as well. Until they fix the focus, the Hasselblad mod is a flaming piece of crap.
I also hear that its aperture is extremely small: it's 2.2 at the lowest zoom setting, and it increases as you zoom more, so it's useless for low light situations.
