I am new to mirrorless. I have a D500 and a D4 and I was holding out to buying the Z9 until yesterday. After watching Steve's review, I placed the order for a Z8. I was surprised to read you can only take 340 - 370 shots, I can take that many on a walk and when I go on a trip, I'll take a couple of thousand in a day. The D5 battery lasted me a lot more than 340 shots. Am I missing something or will I need to carry 3-4 batteries with me now? Thanks
