If I have to prove to you multi-million dollar firms conduct (effective) market research, then I give up.
I study what people/societies/companies/governments do, instead of what they say they do. My observations clearly show that Canon is marking time, because they have either absolutely no idea what the market wants, or they are incapable of providing it. Either way, a failure of effective market research.
Do you also ask for proof that the earth revolves around the sun?
Depends on the point of reference: since the centre of the universe is unknown, everything revolves around everything else.
How about a circumstantial evidence? Sony is down in the stocks and Canon turned a profit. Proof enough for you?
Those two "facts" are not equal: either directly compare stocks to stocks, or profit margins to profit margins.
Marketing (sic= should be market research) dept doesn't count as the few people. They record what people want, they don't impose their own wants.
Then (a) why does Canon cripple their cameras, and (b) doesn't bring out EF-S L-primes?
Trendsetter based marketing is not a basic marketing theory. Is it what they taught you at school? You should ask for your money back.
The fashion industry, Apple, Microsoft, BMW ... you listening, 'cause you're wrong ... not.
This is a very risky technique that will work only under certain conditions: Is the number of trendsetter significantly large? How likely are they to influence the rest of the market? Can the company sustain the slow growth in the beginning until the trend catches? What is the likelihood of competition waiting the initial lag phase and then ramping up just as the log phase is reached.
Is that not why marketing dept. receive the big bucks, to negate the risks?
Yes, that is one possibility. That is why I generalized it to an economically valid reason. However, unlike you I don't have access to Canon's business secrets to state it as a fact.
Don't make such comments that make you look silly just for the sake of arguments. So this is why Sony isn't bringing out FF E-mount lenses? Because very few people need them?
I am guessing you have never used a macro lens, or shoot small birds with a 70-200 f/2.8?
Macro lens: almost every week. 70-200mm f/2.8: I preferred my 400mm for LBJ's, and now use a Minolta RF 500mm with 2X converter.
You are stating the obvious, and acting smug for doing so . Of course the different A7 cameras cater to different markets; my point was, bringing out the A7s while the A7/r setup is still lacking the lenses might imply that the stills market isn't as profitable as they hoped, so they are trying to boost the entire line by bringing out the video-centric model.
And you're stating your same argument ...
