15. Removed "support" for 3rd party batteries...
Yes, this is true unfortunately..All my 3rd party batteries no longer register with the camera so i won't know how much charge they have left..this really sucks.
Sorry about that. However, I guess as you have a number of batteries, you must have numbered them in order to keep track of them. I am guessing that you have a "bin" for charged batteries and another for uncharged batteries. Keep them fully charged. Always keep a spare. More depending on the shoot. Shoot till the battery dies. Recharge immediately (or as soon as you possibly can...). I think that all you will miss is the flashing battery indicator... As for me, even though I have only Canon batteries, I seldom pay attention to the indicator when I am in the throes of shooting. I usually look at it as an afterthought...
When you are shooting video if the battery conks out when you are rolling you are very likely to lose the current shot. It can be recovered with voodoo but its not easy.
No audio on the HDMI out makes that feature less useful for recording as well. You'll need to use a good slate and / or roll the recorder and record on internal then try to match the TC in post. Very disappointed that they hyped this feature and failed to mention the NO AUDIO part. Nikon / Sony HDMI out has audio.
