The real problem with Canon sensor technology?

I am a nikon D7000 user, no doubt the Sony sensor inside nikon dslr are nice, and nikon marketing are very clever to fully utilised those advantages of the sensor as the main tools to tell a very good story about how capable of the camera sensor. But almost recent announced full frame camera are having some quality issues, I not sure how many % nikon user has on hold their upgrade or buying decisions after so many cases been reported. I have the same feeling as the Nasim

I am totally agreed.

Is Canon really didn't put effort to improve their DSLR system? I don't think so. Let's use example, AF System:

D700, 51 points, 15 cross type ; 5DII, 9 (+6) point, 1 cross type
D800, 51 points, 15 cross type ; 5DIII, 61 point, 41 cross type
D810, 51 points, 15 cross type ; 5DIII, 61 point, 41 cross type

D3, 51 points, 15 cross type ; 1DIV, 45 points, 39 cross type
D3S, 51 points, 15 cross type ; 1DIV, 45 points, 39 cross type
D3X, 51 points, 15 cross type ; 1DIV, 45 points, 39 cross type
D4, 51 points, 15 cross type ; 1DX, 61 point, 41 cross type
D4S, 51 points, 15 cross type ; 1DX, 61 point, 41 cross type

Perhaps Nikon has too proud on their 51 af system and the are constantly producing DSLR with good sensor (only?) while I can see the Canon has consistently improving their camera system including lenses. Indeed, Canon is making some better lens.

Wanna know the true reason Canon has not improved low ISO DR much in the last few years?

Because idiots like myself value workflow, ergonomics, quality lenses, reliability, high ISO performance, etc... over having low ISO DR of 14+ stops. As long as us stupids keep buying Canon's innovative and high performance lenses, there is little incentive for Canon to put money into something that will kill short term net profits. If only we were smarter people, we would realize how low ISO DR trumps everything else. We would ditch Canon and let them go bankrupt or be forced to improve their "crap" sensors.

I mean, bracketing my shots when needed and then exposure blending them is like pulling teeth compared to not having the lenses I want to use, or having to fiddle with adapters, or having poor live view implementation, or tiny buttons, or poor customer service, or poor reliability, or poor battery life, or poor ergonomics, or EVFs. or lossy RAW files, or no aperture control in Live View, or no histograms, or AFMA with only one focal setting, or having to press two buttons at once to change ISO, or... well you probably get the idea. ;)

Getting rid of my Canon gear for another brand would be like kicking an attractive woman out of bed for eating crackers. Sure I would prefer her to not get crackers in the bed, but why ruin a good time? :)

Exactly my thoughts. The lenses have far more influence on IQ than the sensor. I cannot see anything close to the 24-70 2.8 II in the Sony lens lineup. Adapters are no alternative. There is no sense in switching to a smaller, lighter body, when using the old and heavy glass with adaters. The only downside of my camera is size and weight. But from my perspective there is currently nothing on the market with the same IQ which has half the weight and size.
