How Many Megapixels do I Need?

I tend to agree with that because you can buy a good used D810 these days for a decent price, and if you ever need to make a huge print, you can always stitch.
When using a DSLR instead of a mirrorless, make sure you use live view for accurate focusing. For critical focus work such as this I don’t trust just using AF fine tune. For instance, with my D800, my 60 f2.8D lens seems to focus accurately at a “0” setting, whereas my 60 f2.8G needs about “-20”, right at the end of the scale. Using live view eliminates these issues. I have a friend with a D810 and he also has significant variances in focus with different lenses.
