Cybershot 707 & Slave Flash Sync Problems

[david h66649]

Does anyone know of flash sync issue between Cybershot 707 and remote slave flash (using flash as sync)?

I shot a party last night using -2- slave flashes.
Could not get the slave flash consistently sync with this camera.

Although the slave flash was triggered by 707's on board small flash, there seems to be a timing lag.

My oberservation is that the 707 delta time between the flash and the CCD recording is shorter than my SLR (is this correct)? Thus the effects of the slave flash was nominally useful.

Perhaps this is an issue with digital camera overall?

Anyone with useful insight, please respond.

Much thanks!

Hi David:

The internal flash flashes twice and your slaves probable sync on the first flash.If you use Sony's external flash it only flashes one time and should work with the slaves.I hope this is correct.

Hi David,

The 707 on board flash fires twice ,the first is a(pre flash), the second is the actual exposure. The slave usually fire with the pre flash, and has no effect on the actual exposure.

You may want to try the VHL-f1000 external flash, should be able to sync your slave.Hope that help.

Most digicams fire the flash twice, your slave would be firing on the first burst and the camera taking the picture on the 2nd burst.

As recommended many times on this forum, I would add my recommendation for http://www.srelectronics.com who sell a range of slave flash modified to work with digital cameras, basically a switch has added to tell the slave to fire on either the 1st or 2nd burst of flash it detects.

These flash units from sr are quite expensive, but the customer service is excellent.

I've already inquired with Sony, they claim via email no other flash units are avail w/707. Will check VHL-f1000 flash to be certain.

I've double checked, this flash does not work with 707

(confirmed by an email from Sony). Even Sony's web site does not list the 707 amongst the supported cameras for this flash, and it is also not listed in the supported accessories for this camera.

In addition, I've already turned off the red eye reduction.
This had no effect on the slave flash sync results.

Any further suggestions?

People watching the flash strobes also stated that there was no 2nd flash from the 707 camera body. The 2nd flash was being emitted from the slaves.

This has NOTHING to do with red eye reduction mode. Your flash IS firing twice - the people you asked simply did not notice. As several other posters have TRIED to explain to you; it fires once for metering purposes, and a second time for the actual exposure.

Additionally, the external Sony flash DOES work with the 707. Several people in this forum own the flash, use it regularly, and have even posted samples comparing the internal and external flash.

Any other ideas?

Yes. Calm down, get your facts straight.

Quoted from Andy:

"F707 with internal flash does true TTL metering. The time from metering (first flash) to image capture (second flash) is 144 ms (milliseconds or 1/1000 sec.). The flash duration is fixed at 0.2 ms, regardless of the flash level setting."

"F707 with HVL-F1000 does not use TTL metering and thus does not have a pre-flash. The HVL-F1000 uses a light sensor feedback system to control the flash duration which ranges from 0.1 ms to 4 ms."
http://www.dpreview.com/forums/read.asp?forum=1009&page=1&message=1651456

Quoted from Andreas P:

"So i bought the HVL-F1000. But what for a surprise, with the attached HVL-F-1000 there is no preflash! Good to attach further slaves but i am wondering if the HVL-F1000 turns the F707 into a kind of stoneage mode (in aspect of flashmetering).???"

David -

I'm not sure if you're understanding the others.

Every time the F707 fires its flash (I'm not talking about the multiple strobing of red-eye reduction mode), there are most definitely TWO flashes: The first is a pre-flash which fires a burst of light after which the camera calculates the necessary flash power needed for decent exposure; then a fraction of a second later, the camera fires a second flash at the power that it has deemed necessary. This may be too fast for your friends to take note of, but it definitely should be operating this way.

When Sony tells you that the other flashes are not compatible, they most likely mean that you cannot electronically connect those flashes to your F707. The only officially recognized flash for use with this camera is the HVL-F1000, which "talks" to the camera via the ACC port on the right rear upper side of the lens barrel. This flash also has its own sensor. It's a so-so flash as external flashes go. But it can get the job done. I like it.

To work around your problem when using slaves, you need a slave that is configurable for working along with cameras that fire a pre-flash. For example, try this place:

http://www.srelectronics.com

They have some very interesting products you may be interested in if the HVL-F1000 is not what you're needing.

David:

Every respondent to your post has given factual information. I also have 707 and the Sony HVL-F 1000 flash and can likewise assure you it works fine.

As Andreas, Ulysses and others state it overrides the internal flash and does NOT USE TTL Metering...it has a sensor on front of the flash unit that shuts down the single flash burst when it measures the reflected light from the subject(s).An "ordinary" slave will react properly.For the built in flash you need a special slave such as mentioned by Ulysses and others.

Trust the responders...they know !

Stephen,

Thanks for your response...

However I wish that it is more worded so harshly, there is NO need to attack people, even when a fact is rebutted (and sources quoted).

While I appreciate your comments, I think it should be presented logically, and calmly. My comments simply rebut quotes from other people's comments who are inconsistent with Sony's response (both in email and through their web page). I've even provided sources to those references.

If the sources I am quoting are wrong, simply correct me and state the facts and proof , not just tell me that I am wrong and get my "facts straight". After all, this is why I am here asking these questions. Doh...

Comments like... have no place in this thread, especially when I did not insult anyone!

Yes. Calm down, get your facts straight

This is my first query into this forum, hot comments like yours turns new members off.

Sincerely,

Thanks for the response!

I did not realize that others were telling me about this pre-flash.
Thought it was in reference to the "red eye reduction" flash.
In addition, I and others could not see this pre-flash...
therefore I assumed that this pre-flash was disabled.

Now I know better ;->
Thanks!

with this camera is the HVL-F1000, which "talks" to the camera via
the ACC port on the right rear upper side of the lens barrel.

Actually, in my email to Sony, I specifically asked Sony whether this flash was compatible. They clearly stated that there are no external flash units that are compatible with 707... period... Let me dig up that email.

This quote from Sony is also consistent with the accessories page (quoted earlier in Sony website), which does not state any flash is a viable option for 707.

I now believe Sony is inaccurate in their response.
Thanks so much for correct this!

I did not mean it as an attack. It was simply a display of my frustration of several experienced 707 users answering your questions which were then ignored several times.

Bottom line is, we've all answered your questions: 1) the HVL-F1000 DOES work with the 707, and 2) the internal 707 flash DOES fire twice [which is probably confusing your slaves]

Stephen,

As a new user, I have to weigh these responses and compare with Sony support rep quotes. Especially when I have data points that are direct conflict w/one another.

In addition, there were several issues that were confusing to me as well as others, and not sure that it was properly asked
or understood by others.

Thanks for taking the time to answer my Qs!

I believe that sony, olympus and several other digital cameras put out a preflash to set up certain parameters. U need to use a slave flash that will sync on the second flash. Digi-slave makes a flash that can be adjusted to fire on the first or second flash.
good luck

FYI:

"Sony DSC F-707 compatible with your units? Any link or comment you can make regarding comparison with the Sony F-1000 external flash: power rating, etc.? About to take delivery on the F-707.

All of our flashes will work with the Sony F707. I don't know how the F-1000 flash is rated, but here are the guide numbers for our flashes:
DSF-1s: 79 ft.
Deluxe 2000: 100 ft.
Deluxe 3000: 110 ft.
PRO: 120 ft.

SR Inc.-- http://www.srelectronics.com/dsf-1s.html

Hope this is accurate,

I've already inquired with Sony, they claim via email no other
flash units are avail w/707. Will check VHL-f1000 flash to be
certain.

Although the slave flash was triggered by 707's on board small
flash, there seems to be a timing lag.
My oberservation is that the 707 delta time between the flash and
the CCD recording is shorter than my SLR (is this correct)? Thus
the effects of the slave flash was nominally useful.

Perhaps this is an issue with digital camera overall?

Anyone with useful insight, please respond.

Much thanks!

Hi David,
The 707 on board flash fires twice ,the first is a(pre flash), the
second is the actual exposure. The slave usually fire with the pre
flash, and has no effect on the actual exposure.
You may want to try the VHL-f1000 external flash, should be able to
sync your slave.Hope that help.
