I need to shoot the X2D II at night more. All I did to this image was to bring down the highlights just a bit and apply LR denoise.
I’m interested to see this. ISO 25,600!
Have you experimented with lower ISO and longer exposure times? I appreciate that this was at 100mm focal length, but it would be interesting to see how well the IBIS would cope with, say, 1/10s (for 100mm). I’m assuming that it was handheld.

I have done that before. In fact, I have been able to handhold at 1s @ 55mm and get sharp images. I didn't think to do that with this one as I was testing something else.

Thank you for taking the trouble to reply so quickly.
Anything remotely like 1s @ 55mm seems like black magic to me although, having said that, it's not out of line with other comments and examples I've seen. I don't really believe that the X2D II's IBIS can give ten stops (i.e. roughly a thousand times) improvement, under normal (as opposed to benchmark) circumstances -- that would surely imply several seconds for 100mm -- but even six stops would be far better than anything I've experienced with full frame cameras. Thanks again,

Here's some more black magic I just took. X2D II + 35-100E 2 seconds handheld.

Thanks! That’s really pretty amazing. It’s hard to judge how much sharper that would have been in daylight, and I appreciate that it’s ISO 1,600, so there are several variables at play here (with a 2s exposure, read noise is perhaps also a factor). Even if we make an assumption that 1/100s is about the limit without IBIS, this is still c.7.5 stops’ worth of improvement. That feels perfectly plausible to me (given the claimed improvement over the X2D).
But, technicalities aside, the essential point for me is that it looks eminently usable. Wow!
