I have found the Nikon Z6, when attached with a flash, sometimes struggles to focus on the subject.

Using Nikon’s NX software I can see where my camera was focusing when I took the shot. As you can see in the full-frame image below, it was sharp.

Then I took a second photo and zoomed in on the couple.

After taking that second photo, I noticed later it was soft.

I wasn’t pleased with all. I had seen this ad pop up on my social media for a while called Topaz Sharpening AI. You can download it and try it. It just puts a watermark on the photo. I tried it with this photo and ended up buying the software.

Here is a closeup of the difference.

While the software improved the focus compared to getting a camera, that is still the best.
