Not Topaz, just Lightroom. I've never tried Topaz, maybe I should. I think that the noise pattern of the A9iii is particularly easy to fix. I don't get such great results from my A7Rv.

Right so about 99% of the work I do is video based. I have a Nikon Z7ii that I’ve been using but the video capabilities just aren’t where I need them to be so I went all in with the FX3. The G master lenses were the other thing that pulled me in

People like me that are hybrid shooters and clients require both video and photography in the same shoots. An EVF is essential for photography so the fx3 is useless to me. We already must each carry at least two cameras for different lens options/backups. Imagine if we had to do the same for video, we would need 4 cameras per person. By the a7s existing, that cuts it down to 2. If the fx3 had an EVF, then maybe I would agree with you, but until that happens, I hope the a7s line never goes away and instead they make an a7siv with 24mp so that the photos have more resolution and it can do native 6k.
