In regard to mirrorless? Yes.
Canon deserves flak. The M had potential but Canon blew the launch and then failed to follow up. Sickening considering how good and economical their initial lenses were, and how good the M actually was once the AF was fixed.In regard to sensors? No.
Fantasy: Canon stands still while Sony delivers us wonderful, ever increasing DR, resolution, and high ISO. Now Canon is best used for Facebook.
Reality: Sony had the jump on base ISO DR when they moved ADCs on chip. That difference hasn't changed, if anything it has shrunk as Canon has gotten banding under control. But this is the one respect in which Canon is truly, actually behind.
improved high ISO over time...even in the 18 MP line...and the 7D2 is the best crop right now at high ISO. Despite its age the 5D3 holds its own against the A7/A7R and D750/D810 at high ISO.
You will never see differences in print between 18 vs 20 vs 22 vs 24 MP, and to see the differences 22 vs. 36 MP your technique better be perfect and your prints 36" or larger. All of the sensors over the past few years have had nearly identical output, but if you bump the MP count the average consumer thinks "shiny new sensor" and "ohhh...if i get this camera my pictures will have 24 MP and that has to be better then 20 MP because 24 > 20, right?" In regard to lenses? No, except maybe on price.
This is where Canon innovates and really delivers, more then anyone else. Heck, there's probably an even split between people who buy an A7 to use Leica glass and people who buy an A7 to use Canon glass! The only complaint is the price on new L glass. Remember when Canon beat Nikon on price to? In regard to service/support? No, they are arguably the best out there.In regard to video? Mixed.
DPAF is actually fairly innovative and a joy to use with a touch screen. But they are clearly protecting their cinema line by holding off on 4k introduction in consumer DSLRs.
And whatever is happening in their firmware people are complaining that their 1080p output is not as sharp as that from other cameras. (And this is a firmware issue because with 18-22 MP to work from there should be no issue producing sharp 1080p. I'll note their JPEG engine might be great in terms of color, but similarly sucks in terms of sharpness/fine detail vs. their RAWs in ACR.)In regard to "wow this is NEW" factor? Yes.
Even though the buying public still runs to DSLRs, those who talk about cameras are enamored with mirrorless. The MILC companies are thrashing around introducing new bodies, configurations, and features hoping to boost sales. Those who talk about cameras see this as "innovation." Sometimes it is, but the reality is that they are struggling with underlying problems that hamper consumer and professional adoption.
Example: The NX1 is "exciting" because Samsung never had anything like this before, and because they have pushed paper specs. The 7D2 is "boring" because the 7D before it was so good to begin with there's not a lot to improve. But which camera actually serves the needs of the sports/wildlife market? The 7D2 because the NX1 doesn't have any lenses, initial reports are that AF still struggles in situations where you would expect mirrorless to struggle, and few action photographers want to deal with an EVF. You can't overcome that with "exciting."
