Not just to open the RAW file, but also to process it and do all the calculations to separate the colours from the recorded data? And I do not know with which tools they use to develop the software, maybe they mainly develop it on windows and use some cross platform tools to make it into a Mac application, making it very slow... Never actually seen their software "in action" the last few years.
I didn't check them carefully at all. It also seems the guy who took the pictures didn't have a lot of time to spend with the camera. Somehow I think, on a Sigma website they only allow good ones. Either that's a wrong idea, or the others were worse...
I have to admit, I never tried various noise settings on RAW converters generally. For that, I need to print to see if there's a change. Since noise to me is no big issue, because I try to get the lowest possible ISO and everything is better than film, I don't use time to fool around with those settings, other issues do annoy more.
The Fuji sample of the "bunker" shot looks very fishy to me.
At least the "bridge" should be tack sharp.
You tried manual focussing with a wide angle on an X-E2? I mean, I could miss but at f/8? Both cameras were focused at the edge of the left tower. And I had to scale the 12 mm up so it could cover the 14 mm. This and the lower resolution of only 16 MP minus the crop are explanation enough for me.
I made another samples with Capture One and increased clarity and structure, but it remains a difference. I would expect better results from an X-Pro2 or X-T2
Does Capture One support Sigma files? If so, I'd simply use that one instead.
:lol: I'm not aware of any other converter for Sigma quattro than Sigma's own. And I checked all of them. Sigma Merrills can be (faster) converted with Iridient - and that's about it. Not enough quattro owners yet. So, those two restrictions: only Sigma lenses available (which is no obstacle because they are excellent) an only one RAW-converter (alright on Windows, too slow on Mac) will keep me away for a while.
Looks like Capture One doesn't support any Sigma camera at all.
I've also found out that repair layer functions are not supported on Fuji X-Trans files. That's not good...
