Name some DSLR cameras that can shoot 1080p at 60fps?




MX


if there even are any. none of the canon eos cameras i've seen can do it.


Answer
The Panasonic GH3 can shoot at full HD 1920 X 1080p at 60fps and at a bit depth of 50Mb/S (around twice as much as any Canon can mange even at lower resolutions) and that's out of the box. With a hack you can get even higher bit depth and even faster frame rates. The higher the bit depth the more detail is recorded, but the faster it fills up the SD card, you'll need Class 10 cards to get this and UHS Class 1 cards for the higher bit depths and frame rates after the hack. The GH3 is the only camera I know that is fast enough to make use of the speed hyke these UHS (Ultra High Speed) cards offer.

The Panasonic GH series is the only interchangeable lens cameras that have video as their primary function. They have a video sensor (not a multi-channel stills one) and a very fast 3 core processor working at over 5GHz. Way more than any primarily stills camera needs.

How can I make my digital camera take pictures automatically until the card or battery runs out?

Hi, I was wondering if you know how I can make my normal , plain, digital camera take pictures constantly until the card or battery runs out? I can solder and am experienced with electronics. Your responses are greatly appreciated

Thank You
Sorry if I made this unclear, but how can I do this without pressing any buttons, like if I wasnt even by the camera while it was taking pictures



Answer
Pretty much all dSLR cameras can do this without any hacking. Just set the camera to continuous shooting mode and keep your finger on the shutter release button.

With cheaper dSLR models you might have to turn the resolution setting down a notch or two. With these cameras the internal transfer speed from the camera buffer to the memory card becomes a bottleneck. By reducing the file sizes you can usually keep things running smoothly - so instead of sending 3FPS at 5MB per second to the memory card, you send 3FPS at 2MB per second.

Same with digital point & shoot cameras - these are simply not built for performance.

Sorry for the mix-up.

Try Googling for the particular application you have in mind. A remote shutter release for your camera in combination with $20 worth of hardware and an evening of your time is probably all it takes....
* A straight intervalomiter is usually built into the remote release itself.
* Trigger the shutter by motion detector: www.image-in.com/fredmiranda/Detector.doc
* By Sound or light detector (+ optional delay): http://www.hiviz.com/kits/products.htm
* Shooting with the camera teathered to a computer: http://www.digital-photo-hobby.com/shooting-tethered.html

Whatever you have in mind, it's probably been done before.
