Question: I'm curious to know what the battery life is like for shooting video. Approximately how many minutes of video can I shoot on one charge?
Document: The battery charges in a couple of hours. I did purchase this 2 battery and AC/car charger combo pack that I'm pleased with.B006ZNBILGAlways nice to have a back up battery handy and the ability to charge in the car is nice too.I bought the EyeFi Pro2 card. My photos transfer instantly to my phone and PC to share within minutes on facebook, instagram, text message, my website etc.
Some of the objects I shoot, white on white, are very hard for a camera to read, this one I just switch to manual focus and no problem. outdoor shots, low light, zoom, video, it does it all well. Battery life is amazing. Even using the flash just to test its limits, the camera keeps going.Previous cameras: Lumix (never again. Quality went down so much), Canon Rebel and Canon D7
I have three batteries total which is enough to get me through the most intense of shooting days. The built in flash can deplete a battery in under an hour. If you are not using flash, you can probably get 4000 or so still images or a few hours of video on a single charge.
I took some pics of a cured flower bud and you can zoom in and see the little crystallized hairs on it! I took a pic of my red towel and zoomed in to see each individual fiber as well as the dust clinging to them.Battery life is good. I have yet to reach full discharge in anything less than two to three days of moderate to heavy use.Another big complaint from reviewers is the lack of manual control while shooting video.
I especially like the dedicated exposure compensation-View finder should be nice when I am trying to get a shot of a moving object with the background blurred (race car, bicyclist, whatever). Not having a viewfinder makes this very hard, I know.-The body feels must more like a tool than a consumer product. I feel confident this camera will last longer. Actually after buying the G15 the S90's ring adjuster broke and has some major lense issue.-Battery life seems betterHope this helps.
I love not having to fuss with a lense cap. A cap makes it tougher to just throw the camera in a pocket or bag. I have the camera with me at all times in this small neoprene and velcro pouchB001EWEB3Uthat I throw in my pocketbook or my hubby drops in in a cargo pocket or clips it to him with one of those rock climbing clips. This case just fits the camera, nothing else.Although I have not counted how many photos the camera took on one battery charge.
I only shot a minimal amount of video since I have little interest in using it, but what I did shoot does look good. The G15 can do 1080P at 24fps. All in all, the Canon G15 is just a great camera.Pros:Excellent image quality.Fast 5x 28-140mm lens.RAW image capture.DSLR style manual controls.Good battery life.Fairly thin and lightweight.3", 920K screen.Optical viewfinder.Cons:No articulated screen.Ergonomics might be awkward to some.
A SanDisk Extreme 32 GB SDHC card will be ideal with this purchase. Amazing battery life in my opinion.Did I mention it feels just, right? It's tank-like construction makes me feel like if I am holding nothing but pure quality! Yes, it's not all metal like the G1X (which I don't really like at all when comparing it to this camera) but it is constructed extremely well. It can definitely survive some punishment!It's video quality of 1080p is superb!
I just clean it regularly and think that next time I want a great video camera, I will get a video camera, but when I want a camera that can go anywhere and take great pictures, I grab the G-15. [Wow, third Canon camera and this one is small and has great battery life, but the pictures aren't great and the HD video, which is why I bought this camera, is horrible because the picture is great, but the sound is rice krispies meets milk.
And in any case, I shouldn't have to use Photoshop on every picture I take.Finally Canon decided to send me the camera back, about a week ago, well into the start of February, a month after I sent it in for repair. They did nothing to it. It still works the same. And I can't send it back to Amazon to get my money back.The camera does have excellent automatic light adjustment and battery charge life, far better than my A570.
Answer: I have a 32GB memory card and empty it allows for just under 2 hours of HD video at the highest quality.  That being said, I'd imagine I could record an hour or more on a single charge as I have recorded over 30 mins and the battery level did not move from full.  Actually, even after taking a couple of hundred pictures in one day, I still have not seen the battery less than full.  This was the same with my old G9...excellent battery life.  It might be possible to fill the whole 32GB card on one charge, but I cannot verify that.
