I don't know if you've tried this or not Bob but it just came to me. You have a grip yes? As I'm waiting for my 2nd battery in the mail could you try something for me? Try recording video with both batteries installed and while it's recording take one out and replace it with another, wait a few min then take the other one out? I want to know if the batteries can be swapped if you're in a pinch...


Thanks,


Mike
