SaSi said:Isn't this whole thing of Sensor MegaPixels equivalent to how fine grained film and how fine grained developer one is using?
I don't think so. The purpose of fine grain film was not to see the grain in an enlargement. It wasn't to get more resolution. In fact grain size has nothing to do with resolution. Sometimes heavy grain was viewed as an artistic option. I don't think noise is considered that way in the digital world.
It seems like buyers desperately need a simple figure by which one can scale the quality, usability and performance of an item. I cars it was (and still is horsepower), in ampliphiers it was wattage, in cameras it is megapixels and so on.
I think this is more for the manufacturer who is advertising in competition with others. I never viewed these characteristics as a mark of quality nor were they ever primary factors in a decision to buy. I could be in a minority, of course, but that would explain why I don't think so.
Megapixels are easy to sell to people who have little knowledge of what they are buying like watts and horsepower. Things like MTBF or weather sealing or lens compatibility aren't very good as an appeal to emotion and emotion is what causes people to make a purchase decision.
