What’s the best way to test the new Nikon Zf? For my test, I chose to visit a mountain saddle in the north of the Czech Republic, a place popular among birds during their fall migration. Biologists capture and release birds day and night from from August through the end of November. In one night, we caught 360 birds and 12 bats. It was cold, rainy, and foggy. How did the Nikon Zf perform in the harsh field conditions? You’ll read about that soon.  But for now, the latest news.
