When you read about this ring flash on the net , you'll reed that it wont work on DSLR's .
And that's right , but you can make it work .
It started for me when i won one of those flashes off Ebay , when i found out about the incompability 5 minutes *after* i won this darn thing . ;)
It had to do with the pins of the flash being different then the ones in the camera .
Anyway , you can make it work by using by using one of those adapters which go on the hotshoe of the camera .
I used 2 of them because i dont have the right one yet .
Two things i need to add beforse you try it .
*Measure* the flash voltage , just in case .
I will not be held responsible if you camera starts smoking !(this would be a malfuntion in the flash though)
The other thing is the restriction of poweroutput of the flash , it only goes at full power .
This means squeezing down the diafragm , at least to f/18 or more .
Hope this helps a little .
Im planing on a more permanent sollution , and this will be posted ASAP .
