The main reason I bought the Nikon Z6 over the Z7 was to have the extra stop for higher ISO and also lower noise at higher ISO.
On Christmas Eve I photographed our church’s service. I was shooting at ISO 51200 at times.
The Nikon Z6 has “Single-AF” as well as “Point-AF” and this week I discovered it is best not to use the “Point-AF” when trying to lock on people.
When I was shooting in the studio I was getting easily 20% out of focus photos when using the “Point-AF”. By switching the “Single-AF” I improved the number of in focus photos.
For accurate focusing I prefer the “Single-AF” over group setting.
Every camera I have owned there is a learning curve. You need to learn all the menu settings and find what works best for your way of shooting.
Hopefully these photos will give you a peak into me learning the Nikon Z6.
