Canon 6D and Tamron 24-70
Not only am I having a ridiculous battery drain, but I am also having a metadata issue. When I go in to check my metadata, the camera has recorded the wrong info into the image file. I used a Tamron 24-70mm f/2.8 VC USD for the shots, but it says that I used a a Sigma 24-70mm f/2.8 IF EX HSM. I called Canon and they had no clue other than it must have been a communication error between the lens and the camera. No, really....? I know that people have been having battery issues, but has anyone had a metadata problem?
Are you keeping yor VC turned on. I heard that will affect the battery.
