Looking specifically at the
Nikon Z 20mm f/1.8 lens
, there were a few things I liked about it for astrophotography. The first thing I liked was the ability to gather more light at f/1.8 at 20mm. This allowed me to capture some incredibly bright Milky Way photos with a 20s exposure. I was also surprised to find that I didn’t feel the 20mm focal length hindered my photos at all. If anything, it forced me to work harder to perfect my compositions. Next, I found that the vignetting was a bit stronger at f/1.8 than I would have liked. Even with that heavier vignetting though, I still found it to be a spectacular lens. Lastly, I also found the
Nikon Z 20mm f/1.8
performed just as well with coma as the
Nikon Z 14-24mm f/2.8
when evaluating the astrophotography images I took.
