This action from Hasselblad is justified in my eyes. Why should they let other make money on them?
Just about what I was going to post. Hasselblad are a business, they want to make money, just like professional photographers want/need to make money. If Phase are taking money out of their pockets in an area where there isn't really a lot of money to start with, it makes sense that they will prevent Phase from profiting off them.
The fact that this may be 'best' for the photographer is simply not relevent to Hasselbald, they are only interested in ensuring their own survival. Which is fair enough and looking at it in those terms what they are doing not only makes sense, but is probably essential to their survival, as the 1DsII has taken a lot of money off people who in the past would have used a MF camera.
Personally I'd like to have the choice of Phase or Hasselbald or whoever backs. But I'd prefer the choice of Hasselblad digital camers vs 35mm Digital compared to the possible option of Canon Vs Nikon and no MF Digital cameras.
