Is there a consensus if 7D ii sensor = 70D sensor?

But is there very a way to compare just the sensor alone? I mean most people trying to make a big deal about the sensor, yet nobody actually take the sensor out of the camera and do the real test with just the sensor alone. Yet they all claim it's the sensor this and that. Even the processor still have something to do with it, RAW file or not there is still some kind of processing between sensor and the memory card. Yet, they all claim to want to talk about sensor. Yes, it's practically impossible to separate the sensor from the rest of the camera, but that's why I question it. As far I'm concern it's about the result images and the images quality.

Obviously we are all talking about the output from the sensor including whatever processing goes on. What we are not talking about is the fps of the cameras or the AF of the camera. These have nothing to do with the image quality.

I just don't get it when in a thread regarding sensor quality that people have to interject things like "yeh, but how does it track focus."

probably uses the same sensor tech as the 6D/70D. I remember a thread on FM where the banding issue of the 5D3 was a bit worse than the 6D at low iso. The sony sensor is on another league, however, you're not going to be a piss poor photographer if you stick with canon. I'm transitioning most of my day to day shooting with the much smaller sony system, simply because I have the option of creating a very small and compact kit. It's not 1:1 as good as a DSLR kit with L primes, but it's still very good.

to get back on topic a bit, the 7D2 sensor is likely the 70D sensor

The 5D3 is definitely better than the 5D2, but you are correct, there are still some banding if you push it enough. I am glad to see that Canon has somehow managed to improve that on the 6D, 70D and now the 7D2. Having any kind of pattern or noise band in an image is very difficult to clean up and still have a usable photo.

Pretty much. I hate to break it to everyone, but if you can't get good shots with the 7Dii, the camera isn't the problem ;)

I can get good shots with my phone. But that obviously doesn't mean that my phone can solve all my photography needs. So why simplify everything into "is it possible to get one good shot"?

the 6D had a better sensor than the 5D3 with a less price
so I think the 70D sensor is better than the 7D II sensor with a less price too

The 6D was released after the 5D3 - you don't think that might have been the reason why the sensor is better? You really think it's the lower price that makes it better and so it's the lower price that must make the 70D sensor better than the 7D2 sensor???

Have you read all the fine prints DxO writes about how they try to isolate and focus on the sensor performance, and how they now and then point out anomalies where a camera seems to bring in processing of the raw data before exporting it to the memory card? The cameras often leave tell-tale signals when they have performed massaging of the sensor data.

I have not read such document(you are welcome to point that out so I can read it), but even if it's true regardless of whether they can point of the processing that have been done, it's still not possible to reverse it. Is the score based on the processed RAW anyway, or do they penalized if any trick being used?

No, they just makes notes if some of the measurements seems to be affected by software processing. They also do analysis of the black data outside of the image area to compare the noise levels and noise distribution there to pick up hints about how the sensor data is being used.

i meant that no one of us knows until we see the samples here in the 7D II thread
not some few samples from the net

No, we don't have all the facts yet.

But why do you think the older 70D has a better sensor than the just released - and still not available - 7D Mk II? Why do you think Canon have taken one step back and made the 7D2 sensor worse?

They could have 7dmkII completed long time ego and only waited for right time to release the camera because of marketing purposes.
So 7dmkII can have 70D sensor with some upgrades.

I said from the first : who knows
how it become a worse sensor ?
I didn't say that , it's a new camera
but we want to see the photo samples here on this forums from the beginners and the pro users and from a different lenses not from one kit lens

But you did write:

so I think the 70D sensor is better than the 7D II sensor

which would indicate that you think the 70D sensor is better than the 7D Mk II sensor. Which would be the same as saying that you think the 7D Mk II sensor is worse than the 70D sensor.

what about the 7D and the 60D sensors ?
are they the same ?
many of you here said yes they are the same sensors
I have used both of them , and i love them both , but sometimes when I see my macro photos with the 7D , I feel that I can take a good photo from the first shot with the 7D
maybe I'm wrong , maybe the focus in the 7D helps , I don't know

:D
ok I will correct that
it's not will be better than the newer
I love the old 7D and for sure i will love the new one

They are the same sensor. They also have the same image processor behind them.
They also have almost identical ISO performance.
The difference is the focus system where the 7D had a dual processor it inherited from the 1D4 while the 60D had a more simplified focus system.

The 70D has the new dual pixel sensor and the digic 5+ sensor while the new 7D2 has a reworked sensor and the dual digit 6 processor which is also a new processor.
And from looking at some images on the net, it does look like the 7D2 brings a bit sharper and less noisy images on the blacks at least, where the image looks a bit clearer there.
