 Re: 5Ds 5dsR - Reality in use? | |
These are subjects that I've thought about quite a bit. However, to avoid hijacking a thread that is actually about Canon 5Ds and 5DsR cameras, I'll forego the opportunity to reply in detail. However, I did write an article about this stuff: https://www.gdanmitchell.com/2017/09/23/mini-medium-format-or-not

Dan, did you ever compare the overall color of files from both cameras? I’ve read reports that the 5Ds has marginally better color than the R but have never seen proof. I’m wondering if the added filter that cancels out the AA filter has any effect on the color output. I only ask because I have had two 5DsRs (one gray market, one refurbished), and the color always seemed less vivid to me than the original 5D or the Mark IV, regardless of the Lightroom profile or adjustments I made to the files.
I did not compare for color. However, a couple of thoughts on that topic.
First, it is my opinion that the stuff about "colors" from different cameras and sensors is overdone. Yes, there are differences among cameras, but they are quite small and typically can be accommodated in post. And they cut both ways — the fact that there is a difference between two things does not always mean that one is better than the other. Sometimes a difference is just a difference.
Second, and speculating here, given that both the 5DsR and the 5Ds actually have the same layers in the sensor (simply oriented differently so that the AA filtering is cancelled in the 5DsR) it is hard to imagine where any significant color difference between the two would be produced.
Third, it is possible that color has been toned down (in newer cameras such as the 5DsR or 5Ds) since the earlier cameras like the 5D. It is also quite possible (actually almost certain) that different raw conversion settings are idea for different cameras, and with those settings enabled it is possible to get essentially equivalent final output.
Finally, I don't have any problem at all getting exactly the color output I want from the 5DsR.
On another note, the 5DsR is a primary reason that I have not moved to one of the miniMF cameras from Pentax or Fujifilm for my landscape photography. Among the reasons is that the output quality is so good from those 50MP full frame cameras that improvements over their performance by going to the somewhat larger 33mm x 44mm sensor don't seem significant enough to justify the cost of the cameras or lenses. I'm confident — I've seen and done comparisons — that even skillful printers/photographers would be very hard pressed to consistently identify the source of a set of high quality 30" x 40" prints that included images from both types of sources.
The 5DsR/5Ds are also just really solid, reliable cameras. I'm not saying that they are the best cameras for all photographers in all circumstances. (I use something else for some of my photography, too.) But if your work aligns with the strengths of these cameras I think they are excellent performers.

Yeah, I'm not sure why, but regardless of the Lightroom profile I used, the colors I could get from the 5DsR file never approached the reality I saw in the viewfinder, at least not the way they did with the 5D and 5D MkIV. But I should specify that it was not with every scene that I had the issue, it was mainly high-contrast scenes of clouds over a landscape at sunset. Living near ABQ, NM, the altitude here is about the same as Denver, but we have incredibly dry air and clear skies. These conditions make for extremely-intense colors at sunrise and sunset, and not every camera I have used has been capable of reproducing them. With the 5DsR, I found that the more extreme the contrast of the light source, the harder time it had rendering rich color, and the more neutral a scene would render (for example, sunlight across a snowstorm in Colorado at around 10K feet. I suppose it feels like they sacrificed a bit of color IQ for the sake of extreme resolution, or like you said, maybe they decided on a more sophisticated color palette for the 5Ds. For what it's worth (probably not much), but DXO shows the 5Ds with a slightly better low-light ISO performance and a scant difference in Color Depth – probably not much to make any difference, but it would seem to point toward there being some difference between the two.
Regarding the GFX/MiniMF, I thought you'd find this quote from the GFX Facebook user group interesting. It doesn't change the fact that the 5DsR is meeting your needs, but it might give you some insight into the GFX's performance versus larger MF digital products. If what this person is saying is true, it would negate the need to differentiate between a MiniMF and larger MF digital – at least as far the end results go.
