Marksphoto: I do wish Canon made a true 5 megapixel 5d version for wedding photographers who don't need 50mp. We want lower noise in the darker venues and I think that would be an ideal resolution with huge pixels capturing dim light. The megapixel race is stupid.

Of course I did. Here is my angle of view:
I would not shoot past ISO 12800 with about any camera. Therefore, better performance at ISO 50k or 100k is irrelevant to me, no matter how many stops better than other cameras.
Now here is what it looks like at 12800:

To me it looks rather that way that Sony handles some noise performance for weaker CFA, giving poorer color. Once you kick colors - saturation and contrast up to the comparable level, you are at the noise performance of the oldschool Canon 6D or Nikon D600 and up. I don´t see how it scales to a point it is worth to pick lower res...

Camera sensors don't scale that way anymore. You won't get so much performance....

Some competition for EOS M3. Good.

FuhTeng: I enjoy their MTF - remarkable performance to have HIGHER resolution for 30 lp/mm than 10 lp/mm! Even the mighty OTUS lenses can't pull that off.

Good catch!
it looks like a typo... Change 10 for 30 and vice versa...

LJ - Eljot: The MFT chart does not indicate the aperture, therefor it is useless.

To me it looks like wide open, but as you wrote, It might not be, and then it would be useless. These lenses want me to jump back to APS-C size...

mosc: Does it have an AF motor?

Nope. Fully manual.

Yxa: Rather pleased with my D800 compared with the 1DXII DR-range
No catching up here, trailing as usual

D800 line cannot give you so mucb FPS, because it is bandwith limited, especially when sitting in lower class and price range, than a flagship. 1D line also cannot do 36Mpx at 14 FPS, right? But you can do 14FPS with higher dynamic range and lower shadow noise. FPS actually doesn't have to close to anything with DR...(Yes, bit depth takes data to move).

justmeMN: Girly Men can't handle a camera that's this big. They have to use mirrorless cameras. :-)

Utterlyotter: I see those manly men in search of mirrorless setup on flagship forums (years later), crying and telling stories about carpal surgery. :-)
I will be one of these, propably...

andyyau: Try to see 80D and 1DX2 skin tone of the girl on the right side. New Canon sensors all produce yellowish skin tone. This is not acceptable...

Nikon, on the other hand, often gives absolutely red, burned look to the girl on the right. And when I try to set colors of the guy on the right to the same as Canon has, the girl goes even deeper red. Not good. Compromises and decisions, that´s it... Maybe different CFA with different spectral response. One quiet minute for oldschool sensors please!

Marcus Antonius: Why is no one talking about the softness in the 1dxII image?
Something went wrong there imho.

Look here: http://bit.ly/1rUiS63

Exactly. WHUUUUT? :-)

TORN: asi if it was IMPOSSIBLE to shoot 14FPS with higher dynamic range. C´mon! Logic101 and healthy thinking. Canon just doesn´t give us any...

Dutchphotographer1: Interestingly, if you select full size instead of comp size in the DR comparison (comp size is the default view for DR comparison, but full size is the default for the studio comparison), the per pixel noise it equal to the Sony. The sony's advantage is only from the downscaling due to the higher megapixel count. On a per pixel basis, Canon has fully catched up with Sony (although with slightly larger photo diodes in this comparison, which gives a bit of an advantage). If canon is able to maintain this per pixel noise on a slightly higher megapixel count for the 6DII and 5DIV, they will be on a level playing field DR wise.

Anyway, I think that far all practical purposes, the image quality is so close, that it is irrelevant in real world usage.

I wonder how big market is there for high DR sensors. But I believe it is big enaugh for manufacturers to acknowledge and act on that. When I looked for upgrade, it was like "oh look", there is (actually old years) like new Nikon with 24Mpx FF sensor and high DR for less than $1000.
And then: "Oh look, there is no Canon available at any price, giving me that DR, and no Canon available in the price range for the resolution, and no Canon available for competing in FPS in that price range (except of crop sensors with even less resolution and DR). No competition in major/vital specs from Canon at all. Then we wonder how come Canons income goes downhill. There is something really crappy about this strategy.

I see. But I would rather go less zoom or no zoom for hetter IQ instead of this. Those qualities of 1" sensor are mostly wasted here.

crashpc: That´s what you get for small lens with large zoom ratio. MF is awesome. FF could "go". APS-C will get the duck and go, and MFT,where it breaks would still pass and go. 1" device? Errr, no. Not with these lenses. Please, do some better lenses for this awesome sensor!

Hhh. Touching flash capacitor contacts is best experience I got from teardowns. It will teach you how to handle unknown things...

phazelag: I wonder where all the arm chair lens engineers who have repeatedly told us what cannot be done will hide now?

jaykumarr: Yes, that might be global consesus of armchair warriors, who propably think that image quality has direct correlation to focal lenght. This might not hold true, as Sony could produce poorer quality unsharp lens, as they did for RX1 (corners).

Canon had this 7 years for us. Now you come to the party Nikon?
It must be Canon sensor, no doubt.
