Nikon new Z7 camera
Typical of manufacturers, they bring out and promote a new camera model and yet getting a spare battery, in this case the EN-EL15b is neigh on impossible. This is the latest reincarnation of this battery but no one seems to stock it yet.
Anyone buying this camera will have to stick with the EN-EL15a for the time being as a spare
Crazy
PS
also can be used on some other Nikon cameras
