I just want to be comparing roughly the same sort of fruit that manufacturers use in their own listed numbers.|

I have the 952AF/PEN and if I go manual it's a pretty powerful flash but in pttl mode it underexposes and if you need a lot of power in pttl it cannot give it for some reason. I know that it can't give 100% because of how pttl works but it looks like it can't match even the 50% power. i.e. where 50% would expose perfectly, in pttl mode it will underexpose by some 2 stops.

Deni, are you referring to the Digital Concepts flash in your signature? Are you sure it's really P-TTL? The flash can fire at full power. I'm assuming that it's the flash and compatablity with the camera. You may just have to use exposure comp or shoot in auto mode if the flash has a sensor.

It can go manually to 1/16, 1/8, 1/4, 1/2 and full power manually though.

Edit: Also, based on an email I just got from Promaster, the FTD5750DX and FTD 5550DX will work with the K200D using the module #7161DXR. Last edited by Blue; 06-20-2008 at 09:25 AM. |
