Cobra d650 for olympus

Will it works in auto mode (no ttl needed)on my k100D ?

Thanks

In theory it should. I have success with a non-dedicated Braun flash on my K10D (using Auto mode). The only possible fly in the ointment could be if the flash has a "ready" pin that's waiting for a signal from the camera - as the layout for pins is different on Olympus it may not work as it never gets the signal. If you can find a non-dedicated flash with just two contacts (+/-) then I'd say that was a better bet.
