works with Sony A7S III and A7C ii
NP-FZ100 Batteries.
I can confirm these work well with Sony A7S III and A7C II cameras, absolutely no compatibility issues and the capacity matches the original OEM ones. Having shelled out almost £400 on six original Sony batteries (which are faultless by the way, just expensive) I thought I'd give these K&F ones a try, just to have a few backup batteries in my bag - and I'm happy to report they work very well...in fact I bought 4 of them. I took advantage of the special offer and got them for less than half the price of Sony ones, which makes it even better.
I initially thought the USB-C charging port was a but gimmicky but I have to admit when all your charger slots are occupied, being able to plug directly into a power bank or a V-Lock with USB port is pretty handy.
I will still go to my OEM Sony batteries first as they have proven reliability but these K&F batts are good enough to keep along side them on long shoot days.
