Not so much a tip more of a thought. There’s been a lot of news recently about the latest Nikon firmware update. It would appear that it gives a more accurate reading of battery status, the same update, so I have read, makes it more difficult to use batteries from independent manufacturers in your camera.
I am sure that there are some good independent batteries out there but I have also heard stories of ‘indies’ giving up the ghost after a year or so. I also worry about voltage fluctuations damaging the camera. Am I being over cautious? All I can say is that in my Nikon D80 with it’s original battery still gets almost daily use, works perfectly and shows no sign of loosing power.
Personally I always stick to the manufacturers own brand. I have just bought a new Leica battery for my D Lux 6 as a backup for those times when I am shooting all day, it cost £70. As I write this I am looking online and have found an independent compatable battery for sale in America for just £4.91 plus p & p. Surely there must be a difference in quality with that price gap, do I want to risk a £1000’s worth of equipment ? No, but you pays your money and takes your choice. I know what I would choose.
