No it's not. We're not discussing opinion here. Noise levels are objective, testable reality. The 7D tests lower across the board (chroma, black, grey). This doesn't magically change with a "real world" scene.
The chroma noise difference in particular is human observable in print where the 7D clearly looks better.
Where does your information come from?
Controlled, published tests by reputable sites like DPReview and Imaging Resource. My personal experience concurs fully.
I've had both and the 5DC is easily better.
Then it should be easy for you to provide test samples to prove the point. Have any? (I won't hold my breath.)
The 7D looks horrible at or above ISO 800.
That makes me think you've never shot one.
What reliable testing do you have to show us.
It's ironic you asked that just before posting DxO links. DxO is not a reliable or reputable site. The errors in their testing have been discussed many times here and on other forums. That they do not produce accurate results is self evident from their more absurd claims (i.e. greater RAW DR than bit depth; APS-C consumer cameras superior to medium format digital backs).
I'll say it again:
* Controlled tests by
reputable sites like DPReview and Imaging Resource show the 7D to be better in IQ across the board than the 5Dc. In a lot of cases the differences are too small to matter in print, but the 7D measures better at high ISO and the chroma difference is human observable.
* Because this particular issue is one of objective, testable reality,
personal opinions don't mean squat unless and until you can provide controlled test samples...including RAW files...which show something other than the test samples that are published.
Sorry to be such a hard a**, but I hate mushy thinking. And FF fans are full of mushy thinking when it comes to this particular comparison.
