A local flash manufactuer is able to produce flash that satisfy your requirement.
I was enquiring about the slave flash for F707 (more info can be found here http://forums.clubsnap.org/showthrea...&threadid=1913 )
and i found out that this company can custom make a flash for me, at an affordable price!
Since the slave flash i mentioned above only have a GN of 24, the manufacturer can make a flash of GN40 (in meters) for me (at ard $90). but it requires a bigger flash body.
i can choose a body that have handle or no handle, zoom or no zoom, swivel or no-swivel. What do you guys suggest??
Since my camera does not support TTL flash, will GN 40 too powerful for an object that is not too far?
If there are more order, i will be able to get a lower price.
This is just an auto flash, so the flash will adjust the power with its own sensor. There are TTL flash too, which is about $100+ (direct from manufacturer's price)
