Yah typically a lens’ sharpest focal point will be in the mid range. Lens’ generally loose sharpness if you open up the aperture to its max as well eg: F/2.8 is not as sharp as F/8. Every lens is a bit different though. The nikkor 14-24 lens I used here is pretty damn sharp from F/5 to F/18. I shot the foreground at F/18 bc I wanted to make sure everything was in focus. I was closer to the foreground than it appears bc it’s a large pano. I could have stopped down a bit more for the sky but the difference between F/8 and F/13 is negligible and I’m not worried about sharpness in the sky. I could also possibly use the sky for parts of the foreground if I get some movement due to wind.
