Hi,
I feel that the discussion sidetracked a bit. These threads always do…
One issue I see is that the discussion suddenly turned into one of those professional discussions, that is OK but it is a bit out of context.
Many MFD users are amateurs, wealthy or not. Nothing on this thread says anything about professional and those amateurs actually buy a lot of gear. Not sure MFD would be around without the amateur/enthusiast market.
Any picture you can show on LuLa could be shot with an early Digital Ixus. It will be a bit difficult to explain how a web size image can illustrate the advantage of 20/40/60/80/100 MP medium format. It seems that there is a lot of ecstasy when a new 80 or 100 MP sensor is released, but those developments are more incremental. Going from 60 MP to 80 MP is a 15% improvement, probably observable, but nut much than that.
The 100 MP sensor is a new game, if you want CMOS. It offers good live view, high dynamic range and good high ISO capability. But, the big news is that it is full frame 645 CMOS, without the crop factor.
I don't think that a larger sensor makes anyone a better artist. For amateurs a new system may offer some new incentive to explore, for true professionals it is more of a tool.
Clearly, some tools are more suited to some tasks, like leaf shutters working with high speed flash sync. But, it seems that demand for leaf shutters is not that high, else we would have a lot leaf shutter systems in the smaller formats.
Another side of the coin is that professional can mean many things. The way it is mostly used it means earning a substantial part of total income by photography. Some operations are large, like Russel Ratherford and some are small. Regardless size of the operation investments need to make financial sense.
Just to make some noise, it may be interesting to check out the meaning of professional on say wikipedia:
A professional is a member of a profession or any person who earns their living from a specified professional activity. The term also describes the standards of education and training that prepare members of the profession with the particular knowledge and skills necessary to perform their specific role within that profession. In addition, most professionals are subject to strict codes of conduct, enshrining rigorous ethical and moral obligations.[1] Professional standards of practice and ethics for a particular field are typically agreed upon and maintained through widely recognized professional associations, such as the IEEE.[2] Some definitions of "professional" limit this term to those professions that serve some important aspect of public interest [3] and the general good of society.[4][5]
Best regards
