Sorry, but I have a 7d and it does not go weeks of use on a battery. I shoot rodeos and the iron man with my 7d and might get by for the day if lucky...maybe 2500 shots. This is in the same ballpark as the A9 when shooting in burst mode.
I think most pro photogs can get by having 2500 shots per battery, especially since you can double that with the grip.
More irresponsible information being spread by people who don't use the equipment but just parrot the internet hysteria.
Yes, because every time you use a camera with a fast burst rate, you need to shoot 20 images at a time, and at the end of the day you have to come home with at least a thousand frames...
I own a pair of 7D cameras, carry one daily, use it at least every other day on average, and literally go months between bothering to charge the battery. Why? Because many times I take the camera out, frame the subject study it, and then don't take a photo... (There is after all little sense in taking a photo once you already know you don't like it and won't use it.) Other times I'm only taking a handful, but I'm often framing photos up for long periods of time without actively capturing images.
And in the original post you quoted me in was also comparing the 1Dx series and its massive battery, and not the smaller one found in the 7D.
I don't have faith in the A9's ability to be ready to take a photo at any time during the day when I grab my camera and lift it to my eye. I've sat for hours with my 7D and a telephoto trained on a target point waiting for the shot (Critters coming out of a den), all the while watching through the view finder, and not put a dent in the battery usage, because the camera can be fully functional while in a mode that uses nearly zero power while allowing you to frame your image and still have no delay on your shutter.
This thread is about whether or not a product like the Sony A9 can doom Canon. Given that the Sony A9 fails to meet use-case needs of many photographers, and Sony does not have nearly as strong level of customer trust as Canon does, it would then suggest that the 'doom' of Canon is rather unlikely based on this one camera.
