I just purchased the Canon 7D Battery Grip from Adorama used and I think I have a problem. When I charge my batteries without the Grip, the number of photos taken return to zero.
When I charged my batteries and put them in the grip, the photos taken are not returned to zero, they do not change from what they had.
Did I buy an older grip or is there a firmware for the grip or something else? I called Canon and the tech had not idea.
Thank you for your help.
Joe
