My X-T4's behavior is odd regarding autoDR with the camera in manual and auto ISO. I found a lighting condition that causes autoDR to engage DR200 and placed the camera on a tripod. If I hard set the ISO with the camera in manual then as long as I set an ISO above 320 autoDR will activate DR200 no matter how high I set the ISO -- 3 stops above nuked highlights and DR200 kicks in. Likewise stops below well placed highlights and autoDR still sets DR200.
If I set the ISO to auto however and use the EC to force auto ISO to raise ISO autoDR basically disables. Any EC value above 0 and autoDR seems to lock out. At first I thought autoDR wasn't working if the camera was in manual with auto ISO set. That's not it. AutoDR seems not to function in manual exposure with auto ISO set and any positive EC value. Odd.
Totally agree that sounds odd. I'm wondering if that has something to do with DR Priority settings, but you don't use those, or some other setting. Don't blame you at all if you're getting those weird responses.
I don't see anything like that on the X-T2 or X-T20, but I'll look into it a bit more. Those bodies don't offer DR Priority - and I'm not interested in it. As I've said - on my bodies - everything just seems to work well on its own. The AutoDR just allows me to be a bit more aggressive with the EC in difficult situations, such as backlit faces. If I go a bit too far, the Auto DR just triggers as it should. No difference AFAICT regarding native ISO or the higher ISOs.
Unfortunately, that's not the case. The AutoDR function is only triggered by the contrast in the scene as it perceives it, and not by any potential or imminent overexposure/highlight clipping condition (at least not with my cameras). Too bad, it would be a far useful feature if it did.
