Theodoros,
I hope my title is not inflamatory. And I never, not once, suggested that 35mm is better than MF. I have a lot of experience with MF, and I know that it is not the case.
I said I made my decision because I worry that R&D money is being diverted away from MF and to 35mm and that we may in future see fewer MF producers.
Have a look at this quote from a Leica exec in Forbes:
There are no industry-wide figures, but we think the core medium format market is roughly 6000 units per year – worldwide, for all brands. We are not yet the market leader (I estimate Phase One to have 40-45% market share), but we already have 20% share – and this is only after 3 years after introduction.
So the entire market is just 6,000 units per year.
And we have, what four/five brands I can think of off the top of my head (Phase One, Leaf, Pentax, Leica, Hasselblad).
Pushing lens and sensor tech forward costs a lot of money, and at 6,000 units a year, I really think we can see one or two of these guys drop out of the race. And I don't want to hold the bag when they do.
