Nikon is really dirty.
They use new firmware update to trap people to update to a version that blocks after market batteries, lenses and so on.
The P7800, FT1 mount, the D5200 victims…
Don’t invest in Nikon, it is a dirt cheap company.

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
