Dual Iso

[Gareth 32]

Does the Xs 10 have the Dual Iso at 640 and 2000? I can't see the difference in noise reduction when it comes to 2000 and Im wondering is it a defect of the camera or is there a setting that I've to turn on. That's if the Xs 10 even supports it in the first place. I'll be thankfull for any feedback because I've been racking my brains trying to work it out. Thanks

The X-S10 sensor is very close to the one in the X-T4, so keep an eye out for any X-T4 results and your X-S10 should be very close. This site publishes listings for various camera bodies, hut has not yet been updated for either of those two:

Thanks so does that mean that the Dual ISO could be a firmware update. I thought the XT4 would have had it since the XT3 had it and they have the same sensor. Thank you for the link and your reply to my question

[jerryy]

It would already have it most likely. That is not really a direct user setting, just something the internal software switches on or off depending on what the user set iso, shutter speed, ev comp, aperture, etc are doing. The X-T3 switches at ISO 800.

Fujifilm sensors tend to be ISO invariant so that also plays into when the switch is made.

Thank you jerryy

This has been a very interesting thread. I never heard of Dual ISO and almost thought it was an in-joke (like "blinker fluid" for cars). To return the favor, I found this awesome video that explains the details, but you will need at least 2 or 3 cups of coffee to keep up:

if the OP is interested in getting information about the X-S10 I'd suggest getting involved and post data to Bill Claff at the Photons to Photos web site so that he can include it in his results

How could someone measure and record this kind of data at home?

Its a bit of a pain - I did it for the X-T30 - Bill's contact details are on his web site - if you email him he'll explain the process.

Just to update this, I believe this was just measured and published here:  https://www.photonstophotos.net/Charts/PDR.htm#FujiFilm X-S10

Glad someone could do it. I got the instructions but it was beyond my frustration level
