The Hasselblad H1 is a completely new camera system,..as far as I know nobody has used it as yet. Here in the UK it is not even available until the summer although it was heavily featured on the Hassy stand at last weeks 'Focus' show in Birmingham. Some of the parts of the system such as viewfinder options were not available to view. this is very much a new and unknown product/area for Hasselblad,...they have not made a 6x4.5 camera before and in my view it raises major issues about the future of Hassy which, as you know has recently been bought out by a Hong Kong operation. Quite simply, it may be the wrong camera at the wrong time since there must now be a question mark over the future of coventional MF slr cameras like the H1 (Contax, Bronica, Mamiya, Pentax) Digital '35mm' models such as the Canon 1Ds offer a cost effective alternative once a collection of lenses is added to the cost since image quality is on a par/better than Mf film images. There are several digital backs on the way for H1(and its competitors) but although they will offer staggering quality/pixel count they will also be staggeringly expensive into the forseeable future and few users will need that kind of image size. How medium formt makers respond to digital slr's is one of the great photo unknowns for all us MF users at the current time. It might pay you to wait and see what the next few months bring to the market place.
