Hanica Sensor Flash as a slave flash

[rty]

Has anyone ever succesfully tried using Hanica Sensor Flash as a slave? I tried taking a few test shots using my camera built-in flash. The Hanica did fire every time but somehow it is no in-sync with the camera shutter speed. Any idea why and how to make it work with the camera?

Thanks in advance.

PS. The camera is Canon EOS D30 set at 1/60.

too slow?

Yes, I believe the Hanica slave fired too slow. Any idea how to solve this problem?

Wuite?

I tried preflash (pressing the * button) and that Hanica slave didn't fire. Only pressing the camera shutter release can make it fire.

Oh gee, I just tried it with my Nikon Coolpix 995 and the Hanica did the job well. What's the matter with Canon?

? Canon does pre-flash under e-TTL before firing the actual flash. (the pre-flash helps the camera gauge how much of the actual flash to fire). The pre-flash probably trigger the Hanica slave to fire before the shutter opens.

CP 995 doesn't do pre-flash. The flash only fires once.

If there's the case, any workaround to disable the preflash? I didn't see any pre-flash fired from the camera built-in flash though.

saw some discussion: http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=001gr6

basically, you need to find a way to disable E-TTL to prevet pre-flash....

Err... I didn't use any external flash for this experiment. I also have tried using my built-in flash of the Canon camera to trigger those big studio flashes and it didn't work either. Nikon and other cameras seem to work fine.

:dunno:

The internal one has preflash I think. Like others said, the initial flash will trigger the slave already. And they probably don't recharge fast enough to fire again during the actual flash.

Try using a dumb non-TTL external flash unit or one of those IR flash triggers on your hotshoe instead. All else fails, you can always go to the Nikon camp. :devil:

Your built-in flash always pre-flash, but you can't see it because it is just a fraction of second before the real shutter-flash fired.
Use external flash (and don't use TTL).

If all else fail, then as CK said: welcome to Nikon camp, the world without pre-flash :devil:

Nikon does pre-flash with the "3D Matrix balance fill flash" right?

Ronnie: Ckiang is right. I use an Achiever 260T on my D30, covered with unexposed slide film (which I got from him). Triggers off the studio flash very nicely. Cheap wireless solution.

It does it inperceptibly. And can be easily disabled. At least on external flashes (I don't have a Nikon body with internal flash to verify)

Alright, thanks guys. I still have another flash to experiment with. It is an ancient and super dumb Kakon flash that uses 4 AA size batteries. Will probably experiment with it tonight. I just hope it won't fry my D30.

ckiang & tsdh, I have given my sworn allegiance to the Canon camp so defecting is not an option. Thanks for the asylum offer though.

How much is the Achiever 260T? The $22 Hanica can do the same job, you know?

duh.... my Canon camera (EOS 30 not EOS D30 ) does trigger the studio lights through flash sync via built-in flash.

u have to note that the flash somehow got to reach the flash sync detector, maybe at the back of the studio light unit.

if that fails, use a sync cord. that's the safest!

Beware of excessively high trigger voltages of some flash units. it can try your D30. (doesn't matter if it runs from 4 batteries or powerpack, etc) But hey, that will make a good reason to upgrade to D60, 1D, 1Ds, etc. :devil:
