Let me take your quotes,
"Canon should have expected that many buyers of this range of cameras will be the ones relying on it for a living and will be those inspecting their photos at 100% to ensure they deliver the best quality."
"If you don't worry about detail...then why do you need to buy a 21 MP, full-frame camera?? Unless people are doing seriously large prints there aren't too many compelling reasons for a HUGE, high MP full-frame camera's "detail.""
"If you don't need big prints...or serious cropping...you don't need that kind of detail and you don't need a 5DII. If you only take photos in bright daylight and only print postcard-sized photos, a good P&S like the LX3 will give photos that are almost as good as those taken with a DSLR."
The last statement is an absolute statement which is representation of your assumption and opinion.
Based on the above,
Aren't u speaking for pp based on your own perspective? And for all I know, u dun even depend on your camera for a living and yet speaking for them.
I use words like majority or most which does not constitute everyone or 100%. My views are based on my personal interactions with other professional photographers and interaction with my customers. The use of majority may not be accurate per se but it is the perception I get in my few years of interaction. I also presented different reasons in getting a full frame camera other than the megapixel count. I think some forumers are right. I think u need help in your semantics.
I think u also need help in your statistical studies. I have not seen the poll that u mentioned. But based on the polls conducted in clubsnap, it is seldom reflective of the whole community in clubsnap. Adding to that, it also does not include the type of photographers who submit the poll. Who are the ones surveyed? What is the age group? Hello, go back to your statistical studies.
