As we wait in feverish anticipation for Michael's medium format back review - a good idea, in my view - here is something to whet the appetite.
Digital Photographer issue 9, a decent pro/enthusiast publication in the UK, has this combination on test, with sample images on the included CD Rom.
The ' blad gets 92% - a rave review really - and the Kodak 645H gets 84%, described as a worthy competitor to medium format film, and in most repects faultless. So, pretty enthusiastic. Mind you, a magazine called Digital Photographer is unlikely to rubbish the latest digital technology.
The price of the combo is of course stratospheric.
