Introduction

The Fuji X-S10 is the winner in the ISO performance contest?

The Z9 has arrived, but the weather is gray and cold. No one feels like modeling at an outdoor sports shoot. So what else could a geek do but put the camera to the test. I have a Z9, a Z6 and a D850. My girlfriend has a Fuji X-S10, so I thought why not put this little APS-C camera against its full-frame counterparts. Surprisingly, the X-S10 turned out to be just as good as the Z6. Above ISO 6400, maybe even a bit better, since the grain is more monochromatic (or did I do anything wrong? Tell me).

Ok, so what about the Z9?

I think the Z9 is a little bit better (not much) than the D850. But worse than the Z6 and X-S10.

I would say, we have a first and second place. Z6/X-S10 on first and D850/Z9 in second place.

Test setup

I tested all cameras with the following settings:

• Shutter speed: 1/200s
• Aperture: f/8
• Lens: Tamron SP Di VC USD 35mm f/1.8 on the Nikons (with FTZII) and Fuij XF18-55mm F/2.8-4 R LM OIS
• White balance: flash
• RAW Processing: Capture One 22
• 10-second timer (Nikon cameras only)
• 100% crops

I used a Godox AD600 Pro flash in TTL to compensate for ISO settings.

Exif data is included.
