It's all good.... my 7D is plenty enough for now and I must say 22mp can't be the real number given the D800 specs... Why would Canon develop a sensor of this size when the 18mp 1Dx sensor would suit just fine AND lower costs??? A 4mp difference is stupid, so I'm calling bull on these specs.
The sensor has to either be:
Crazy high mp equal or higher than the D800
1Sx sensor @ 18mp
This makes very good sense. I cant either understand why they would have a 18MP and a 22MP sensor.
Perhaps they have designed them completely different with lower read noise and DR for the 22MP and only focused at high ISO for the 18MP sacrifying over all image quality?
Or perhaps they just sacrified IQ at all ISO for the 18MP to be able to get higher FPS?
Why would an 18 Megapixel sensor "just sacrifiece IQ at all ISO"? surely it would make it easier to improve image quality at higher ISO's while also allowing for faster FPS.
Each sensor seems like its tailored to its purpose for me, the 1DX likely having better ISO/FPS and the 5D3 better Resolution/Video.
I'm sure marketing is a big issue aswell, even if the 1DX sensor offered superior actual resolution to the 5D mk2 it would be difficult to sell a reduction in megapixels.
I just pointing out the strangenest with the small difference of a 18MP and 22MP sensors.
If there shall be any difference between them then they must have been designed very differently. If they have almost the same design but just different pixel size the 22MP will be the better one at all ISO, but it will be very close to a neglectable difference - So better use the same sensor for both.
One simple answer could be that the sensors are close to the same but they made a choice to sacrify IQ, of the 18MP, at all ISO to get the higher FPS. The sacrify would be very close to neglectable anyway. But then again - why not just use the same sensor for both
Another answer could be that they have a total different design. Then perhaps the 18MP could be targeted towards absolute best possible high ISO and the 22MP targeted toward hights possble DR. Then the 22MP could have a sligth edge at low ISO and the 18MP could have a slight edge at high ISO. It could also be the the oppisite but that sounds more unlikely.
Another horrible possibility is that the 18MP has a new improved design and the 22MP use the same poor technology they now have been using for many years with small upgrades for new generations. In this case the 22MP may only be a very minor improvement to the old 21MP while the 18MP is a significant improvement.
But why would they be stupid to do such a thing when it would result in very bad sales for 5D3.
No, I cant get it with the very strange small difference between the 18 and 22MP. We will have to wait and see.
