You aren't paying x dollars per megapixel, you're paying for the camera on the whole.
True that. I'm looking at this as an existing R6 owner who bought the camera for the pixel quality as-is, so for the most part the interesting part is the sensor itself -- the rest is mildly interesting. I'm not "upgrading" from an R8, or a DSLR, etc. Nor would I be "downgrading" from an R1 or R5. Body robustness, vendor SLA, customizability, etc. all have their part in total value. I think the R6 III is overall a great total value, based on what I'm reading.
In this case, objectively, just downsizing is the worst-case scenario, as I mentioned in the article.
Yes, you did mention that — I saw your later remark about downsizing. It was very interesting to note.
Honestly, I was partially grumbling out loud in the background of my day job when I saw the downsizing remark — and many other times in the forums people have been like, "well I just use my ($2K more expensive camera) to down size and then I'm good to go if I need that quality." And, hey — that's not wrong. But I think that attitude mostly misses the point about whether the sensor for the R6 line moved forward, held steady, or lost capability in one or more ways; let alone the fact that many people making the move will not be gaining more in terms of body (not much changed from the R6 -> R6 III in the body department) but rather
will be purchasing
for more megapixels — so downsizing an image just to reclaim their prior capability in noise (etc.) seems to miss the point of the purchase for
that crowd. I mean, the R6 -> R6 II was effectively the same quality in all regards for more pixels and without the need to downsize. Win all around.
I'm also an engineer and scientist responsible for the day to day operation of an analytics company focused on advanced medical research at the cellular level. How a comparison happens, and what that comparison informs, really matters to my teams. For most people it probably is a "close enough" situation.
You did a nice job with the article, and it was the first such piece that answered many of the questions that I had about the new sensor.

In the context of what I mentioned above, the fact that downsizing is the worst case scenario was very interesting to me: contrary to the oft-heard chant of "just downsize to get the same quality" that does not seem to apply here -- downsizing doesn't get a person back to square one in all quality factors if the "one" was the prior R6 or R6 II. And Canon did leave the R6 II as an option. People get a real vote here with that choice of R6 II vs R6 III when both are left on the market. Aside from a desire to clear old stock, I wonder if Canon is watching for the hint of any other purchasing preference / attitude while both remain.
Thank you and the team for all of the interesting reads of late on histories, capabilities, etc.
