Saying "it depends on what they shoot" works both ways. The list of photographers I made represents an extremely diverse range of shooting conditions, subjects and styles. Their work is out there for anyone to see. The work of antonymous sensor critics on the internet is ... not as visible. So claiming to having higher image quality standards than some of the best photographers on Earth is pretty dubious.
Image quality is, to me, not very subjective. I'm only considering the results produced by the hardware used.
I'm not alone here with very high quality standards in that regard.
If you haven't run into such hardware limitations you're staying within your handicap. If you're using various workarounds "that have been around for a century" then you're accepting a compromise or exercising an artistic choice to work within those limitations.
Some of us have artistic choices that require better hardware with less limitations to fulfill. That's how progress happens.
No doubt some of those photographers have complained about things they wish to be improved, and yet they still shoot Canon. Perhaps they know more about image quality than anonymous critics on the internet.
No one said that Canon is perfect and no one says "how dare you not declare so and so brand to be perfect". Describing people as getting defensive or agitated about "how dare you not declare so and so brand to be perfect" is just a big, fat, empty straw man of an argument, just a deliberate misrepresentation of what people are actually saying in this thread.
I think he was paraphrasing.
Some people here react to this debate far too emotionally, with lots of passion and only a few facts.
The OP has not only shown examples, he's also provided his raw data and used a lot of his personal time and resources to do so, only to receive insult on top of (literal) injury.
Some of us have bolstered his findings with more examples.
Point is, these are facts, not opinions, about sensor system capabilities of Canon vs Sony.
It can be summarized as such:
- Canon is good enough
- Exmor is excellent
... in the one sensor metric where they differ substantially, low iso SNR and FPN.
