Brand : Kako 9000 (cannot find any info online, anyone can help?)

Colour : Silver (match with most digital camera, but the build is not very good)

Guide Number : 24 @ ISO 100

What's included? Flash, a horizontal adapter for those camera WITHOUT hot shoe, sync cable....etc

Warranty : 1 year

What's so special abt this flash?? Some camera have pre-flash and red-eye reduction, therefore u cannot use a normal slave flash becos it will trigger at the pre-flash instead.

This flash can set to trigger on SECOND flash, that's why it can work perfectly with F707. You can also set it to trigger at BOTH pre-flash and second flash, but it will be a bit weaker. Anyway, here is a simple test, i dunno if the method i use is correct or not.

Shutter : 1/1000s
Aperture : F4
Exposure bias : 0EV
F707 manual mode, red-eye reduction disabled.

No external flash, just use F707 build in flash


Set to F2 mode, that is, the slave flash will fire twice, once on pre-flash, once on second flash


Set to F1 mode, that is, the slave flash will fire ONCE, only on the second flash


See the different??
Wiily, are u free to go peninsula with your F1000, then we try out if this flash is as poweful as your F1000 or not.

There is a sync cable, i wonder if it is used for connection to another slave unit and trigger via cable.

BTW, the flash head can be turn 90 degree so that u can fire at any angle u like, also there are 4 different zoom level, from wide to tele(what's the proper name for it??)

I will try to do more tests on it, anyone interested to get this flash together? Probably can ask for more discount if we buy in bulk.

Listed Price : $88 (haven't bargain yet)

btw, take a look at the reflection of the flash on the glass

the first photo, u will see a small spot of light, cos only internal flash was used

the 2nd & 3rd photo, u will see a much bigger spot of light, cos both flash was used.

if the sync cord can use to trigger another slave flash...wow..i can put two external flash on my camera, one on the cold shoe, another on the horizontal mount that come with the flash

1/1000 seems really too fast... even for the internal flash (I think). Try 1/100? or 1/60? Hmmm... this seems nice thing to have since my camera doesn't support wireless flash. Can use for ratio flash or illuminate background.... Nice~

So 90 degrees up and down? And where can I find this?

Let me clear up a misconception here... (learnt this from someone who posted this sometime back)...

Aperture affects flash while shutter speed affects ambient light..

So while 1/1000 probably affects the flash slightly, it's way too fast to capture the ambient light...

I would probably try F2.8 - F3.2, 1/30 - 1/60 to be able to see the difference in flash properly..

Geez. Just read the guide number, and test the flash at the limit of its range.

why not we go down to MS colour at AMK or TCW at peninsula to try it out?? See if it is as good as the Sony's flash.

you probably need 1/60, 1/125, etc to allow the flash to fire fully .

Is the guide number in meters or feet? Some use feet, some use meter. The Sony one is definitely more powerful.

Anyway, is it an auto flash? Is there a sensor that detects the amount of ambient light and fire accordingly? It would be better to get one with a light sensor.

couple weeks back there was a Dutch auction on Ebay by a US online store selling the Digi 2000 (US$119.95 list) for US$49.95! Even after US$20 3-day Global Priority Airparcel... thats less than S$130 for a quite capable flash. But I already got a cheepo one and don't take too many flash photos anyway... Good thing abt slave flash is that can use for any model, brand and type of camera.

Hmm, so what happened to the order?

A good GN40 (meters) flash would srue be useful for these long range, short exposure shoots - such as shooting these models catwalking. :D

Btw, can it be tweaked to allow for subjects that are closer?

There's another one. More expensive though (a Metz 34 CS-2)

KC, I check the spec for the Metz 34 CS-2 which does not have slave flash function. How come this guy claim he use it with S30 as slave?
