Re: 10 bit vs 8 bit output
The F3 is more power hungry than the EX1, mostly due to having to power 3 x HDSDi outputs, one composite video plus HDMI at the same time. It also has a small (but very quiet) fan that runs when the camera gets hot.

If that was solely down to powering HD-SDI outputs (the FS100 is powering HDMI itself), surely it would be sensible to provide a means of disabling them when not in use? (Most of the time, for most people?) And other cameras with HD-SDI don't seem to neccessarily have such power requirements. |

Re: 10 bit vs 8 bit output
When the dual-link connectors are turned off (yes, you can disable them), the F3 only uses about 18 watts. As a comparison, my F800 uses 45-50 watts even when the SDI connectors are turned off.

Re: 10 bit vs 8 bit output
The power difference does not surprise me one bit. The FS100 and F3 are as different as night and day except for the actual image sensor.
Just about every high performance product I can think of (cars, computers, digital cameras, appliances) will use more energy that a lower-performance equivalent. There's a hell of a lot more computer processing being done inside an F3, plus you have both a viewfinder and LCD, and two SxS card slots that each require a lot more power than an SD slot. Also, I think by it's very nature, a 12v camera is going to consume more power than a 7v camera. Although I am shocked by how long my FS100 will run on a single battery, I am still completely satisfied with the battery life on an F3. Anyone who is not happy with how long modern batteries will power modern cameras has not been in the business very long. Wow, people are really getting spoiled. :-)

The amount of power sipping the F3 does is very welcome. My Dionic 90 will power my F3 for hours upon hours, with a recorder built in! |
