Question: Does this camera come with a battery and charger?
Document: The camera doesn't come with an external charger. Battery charging is done through the USB cable attached to the camera and plugged into a wall outlet. That's fine if you get everything you want on the card and then come home and charge up, but if you find yourself low on battery in the field, you may be out of battery before you're done.
I have not used all the features nor have I downloaded pictures to my computer from the camera, but it is a good camera. I purchased this to replace my earlier model lumix when a trip to the beach did it in! The small size of this camera makes it convenient to carry in your pocket or purse.It does come with a battery so I did not need to purchase the batteries and charger as I did.
The battery that came with the camera will not take a charge or it's the actual charger that came with the camera that is not working. Going to contact the seller for a resolution today. Not to happy, needed to use it for work this week.
I bought two batteries, blind, and hoped for the best. To my surprise, they lasted longer than the original battery!So, with two spare batteries and an external charger, the ZS30 really delivered and I am happy with it. It is now my carry-around multipurpose camera, and will last me a long time.
Possibly related to (1), on two or three occasions I've reached for the camera to find that the battery was dead, even though I'd charged it recently. This is unacceptable in a pocket camera -- it's purpose is to be ready when I spot something interesting. (Also, no charger included with the camera. Pretty darned cheap of Panasonic, given the price tag.)3. I love the panorama feature, but they've crippled it.
So I found an external charger (in Japan!) that works with the model's battery until Panasonic releases its own. Yes, unfortunately the ZS30 does not use the same battery as previous ZS's...Which reminds me of another annoyance regarding Panasonic: whenever they release a camera with a new battery, it takes MONTHS until spare Panny batteries are available for it. Being on a deadline and unable to find original Panasonic batteries, I shopped around Amazon and nearly hit a wall.
The GPS does work and like all portable GPS devices it depletes the battery very quickly. Come to think of it the battery life even with the GPS is fair to poor on the curve. I've not tried the Wi-Fi and except for a quick download to a smartphone, I not sure why one would use it rather than taking the SD card out and using a reader and a USB plug. But each to his own.
Better results than with my Canon or Sony. The built in charger means you can top off the battery no matter where you are without having to carry an extra charger. We usually charge up at night, but carry an extra battery just in case....Absolutely no buyers remorse, here.
Oh it does come w/ some extras GPS things & photo program. I used there photo program which is utter poop. You can ONLY put lumix pictures into the program. Say on your SD card you have pictures from another camera, ugh uh, cant put it into that program. So I bought a separate photo program.
This didn't present a problem because I had bought a charger and 2 spare batteries. On any one day I never needed more than 2 batteries, but had that third just in case.
Answer: Yes it does. I did however have to buy a memory card. The internal memory if the  camera was full after a couple pictures only, not sure why. But the memory card is only an extra $20, and the camera is  worth it. I love it and would highly recommend it. It makes great pictures, and is very easy to use.  Hope this helps!
