Canon seems to do well regardless of whether their technology is the best or not.
Aah. You must have missed the discussion about the last quarterly results from Canon and Nikon.
DSLR sales at Canon were down for the quarter (compared to 2011), while Nikon's sales were up.
Canon blamed it on the strong yen and delayed introductions.
(How is the strong yen affecting Canon but not Nikon
The fact that Canon is down for a quarter is certainly not a big deal.
But if you are down while the competition is up, then you have reasons to be concerned.
Overall, Canon was not doing all that well last quarter.
They've been overpricing left and right in the last year - but if the last quarter is any indication, their overpricing strategy is not working out.
