There’s lots of talk today online and in print about open camera system architecture…that is to say, a camera system that will accept different camera backs (medium and large format) and perhaps even lenses made by different manufacturers (see new Zeiss and Voigtlander offering for Nikon).
Hasselblad of course screwed up this warm group hug and collective back rubbing with the introduction of the H3 which is a closed system (read: they want all your money) – definitely a lame move on their part.
The best (most flexible and cost effective) open system to date is: analog FILM married to a good scanner. Lots of options with a minimal investment and proven, time-tested technology to boot.
The best- or at least coolest- digital open system so far?…consider the Hy6 (you know, if you have $30,000.00+ just kicking around)!
I, for one, will stick with the film option.
