Re: power

Dear Friends,

The wattage is expected to increase a little when more features are turned on in the F3, and one is using them.

The voltage is dependent on the power source and its ability to supply the power required. The voltage will never increase (from normal power sources) if the camera needs more power.

I hope this helps.

I think there's a confusion (or typo) here...
Camera will be drawing 18-24 Watts (at ~12 volts) with everything on (maybe even a little more assuming that we've all convinced Sony to allow us to have HDMI and HD-SDI and Dual Link all turned on simultaneously in a future firmware release.

From the Manual---

Power requirements
DC 12 V (11.0 V to 17.0 V)
Power consumption
Approx. 18 W (Typical) (HD-SDI Dual-
Link Off, VF On, LCD monitor Off)
Max. 24 W (Typical) (HD-SDI Dual-
Link On, VF On, LCD monitor On)

Thus connecting to a 24v power source would be a BAD IDEA!

I know that Junior at EC Professional had verified that the camera would run off the BC2 charger/power supply, but at this point he probably wouldn't have had Dual Link on, so I'm guessing he was at the lower end of the power spectrum.

Re: power

Here is a compact power supply from Switronix that should deliver a constant 50 to 60W.

Re: power

Thierry,
I just bought that power same Switronix power supply at B&H.

Also at B&H is an identical charger sold by Bescor, for around $30-$50 more.
So, don't spend more thinking you're getting a better one.

Re: power

Has anyone tried an Anton Bauer Tandem power supply/charger with an A-B to 4-pin adapter?
Seems like a reasonable option since it auto-switches to battery power (if you put a brick battery on it) if you lose AC power. It's output is listed at 16.4v and 4.25A. Plus it charges the brick when not powering the camera. I've just never put a 4-pin adapter on it, so wondering if anyone else has...

Re: power

I have the Switronix on my "things to get" list as well. No sense in messing around with something critical to operation just to save a few bucks.

Re: power

Dave, Sorry for the typo and confusion. I meant watts, not volts. I too am running off the BC-U1 charger/supplier by soldering a Canon 4 pin as suggested by Junior, and measured output from Pin 1 & 4 at 12.1 volts, while the DC out at the charge end of the unit (flipping switch to charge) measured 14.4 volts. It's not the prettiest thing having the charger dangling around but I thought I'd play with it for awhile and see if it'll work when we can turn dual link and all that other good stuff on.

Re: power

I use a Anton Bauer battery charger on my lite panels 1x1 for 12 volts DC out. No reason it can not function powering the camera as well with a D-tap and XLR power plug.
