On top of that, it's about 1/2 stop darker. The reason Canon looks cleaner is because it's smaller size so when you try to compare 100% zoom, the noise isn't as noticeable. To me, noise wise, they were actually more or less the same (I downloaded the raws). The reason why your test shows Fuji being cleaner is because it's about 3/4 stop darker compared to the other 2. Trust the information you have and more importantly, trust your eyes. ![]() We know the images were underexposed by 3 stops, just add 3 stops back. From what I've seen and tested, it doesn't work perfectly so it shouldn't be used in a test. You're blindly trusting some algorithm, Match Total Exposure. They are raw files, they need sharpening. Keep in mind Fuji is using a f1.2 lens while the other 2 was using f1.4 so that negates any exposure difference. The reason why Sony and Canon files were at ISO 100 while Fuji was at 125 is because those are their base ISOs. No one tests with sharpening off because no one edits raw files without sharpening. Most likely the sharpening was set to a value, as it should be. If I’m missing something-or did the test wrong-please tell me, but I think I’m correct here. In actuality, the Fuji has *significantly* less noise when accurately matching exposures. I set the Noise reduction and sharpening for all three to “off,” set the Develop Profile to Adobe Color, set the Fuji image to +3.00 Exposure, and then chose Match Total Exposures for the Canon and Sony (which put them at +3.77). Doing so gives you a better overall comparison. This makes a difference in this test, and Lightroom notices the difference when you select all three images and choose “Match Total Exposures.” If I set the Fuji image to 3-stops overexposed, add the other two images to the selection and choose Match Total Exposures, Lightroom actually kicks the Canon and the Sony up to +3.77 overexposed. I also noticed for this test that the Sony and Canon images were shot at 100 ISO and f/1.4, while the Fuji was at 125 ISO and f/1.2, all at 1/4000. I say this as a full-time Canon user: I’d have to run that Mark II image through Topaz AI or DxO PureRAW before being able to deliver it to a client. I think the Fuji has an overall film-like grain to its underexposed image that could even be labeled as “aesthetically pleasing,” while both the Canon and Sony images have so much chroma noise, as to be unusable. ![]() ![]() I think your conclusion is incorrect here. ![]() This could be a result of the X-Trans sensor array. There is significant chroma noise in her hair for both the Canon and Sony, while almost no color noise with the Fuji. For the “3-stops Underexposed” test, the Fuji does have more overall noise, but I would argue that it’s luminance noise-like film grain-rather than chroma noise (color noise). I would be curious to see a repeat of the ISO tests with all noise reduction and sharpening set to Off.Ģ. It is entirely possible that Lightroom is applying different noise reduction and sharpening defaults for each camera, much like Fuji images have embedded lens profiles. This would be significantly relevant for the ISO tests. Are the Sharpening and Noise Reductions settings in Lightroom set to “off,” or to the “default” settings for each camera? I don’t think we should assume they were *identical* unless they were confirmed as being such.
