Comparison R5-R-RP-5D2. Pixel sharpness is back to 2008
2

Hi pixel peepers,
I developed raw files of the DPR studio scene in DPP for a comparison without any noise reduction. Notable findings:

- The R5's praised pixel sharpness is just what it was on the 5D Mark II (which in turn is almost identical to the even older 350D). The R and RP are a lot softer on the pixel level, and the RP's detail is identical to the 5D2 in spite of the latter having "only" 21 MP.

I confirmed this with test shots with the Sigma 105/2.8 Macro. The 5D2 shows a bit more aliasing, but compared to the RP, pretty much all detail is there.

- The RP's shadows seem to be a bit brighter. If this is equalized, the difference to the R's sensor gets smaller, and even very slight amounts of Chroma NR clean up the color blotches nicely. This is a lot better than with the 5D2.

- Most advancements concerning noise, though, seem to come from baseline NR or other tricks in the raw converter. With truly no NR, output is a lot more similar. I remember the newer cameras are also 1/3 stop darker at the same ISO setting, though I did not see this in my own testing because I used an ETTL flash.

A few remarks and questions:

- Are you sure that your lense is able to fully utilize / outresolve those high MP sensors?

- Your flash is too bright. Most of the whites are in saturation + a lot of detail is lost at sharp contrast edges due to the high flash intensity

- Link to the DPReview comparison tool: (https://www.dpreview.com/reviews/image-comparison?attr18=daylight&attr13_0=canon_eos5ds&attr13_1=canon_eosr5&attr13_2=canon_eos5dmkii&attr13_3=canon_eosr&attr15_0=raw&attr15_1=raw&attr15_2=raw&attr15_3=raw&attr16_0=100&attr16_1=100&attr16_2=100&attr16_3=100&normalization=full&widget=1&x=0.08803681295429054&y=0.28633311109490583)

- What is your take on the results from the dpreview comparison tool? R5 + R are a lot better, RP slightly better than the 5D II. Do you think they use noise reduction if "RAW" is selected?

- Can you share your results from the dpreview comparison tool?

Most lenses outresolve most sensors by far, otherwise we would not get results near the sensor resolution. Scanning something at its own resolution about halves it.

Well, it's not my flash, it's DPR's. These are Raws from their studio scene.

Their Raw developments are done in ACR, which used to apply baseline noise reduction that cannot be turned off. Not sure if this is still the case, but DPP has always delivered the most "pure" output I could find, apart from free software like dcraw (which has problems getting the colors right).

Therefore, I think the comparison tool is most effective for people who also use ACR or camera JPEGs. I don't use either so I thought I'd compare with DPP output.
