Off shoe flash

Hi all,

When using the 550EX off shoe (using Hot shoe adapter 3, connecting

cord 60 and off-camera shoe adapter OA-2)the flash switch to TTL, and

it seems that it's not possible to compensate for the flash exposure

anymore. Do I need to use the flash exposure compensation on the

camera itself when the flash is off shoe? But I thought that the

flash exposure compensation set on the flash unit overrides the one

set with the camera... So I am a bit confused here..

 

Cheers,

The hot shoe adapter and connecting cords do not support

anything other than plain TTL. This means you lose a lot of other

functionality, such as E-TTL, second-curtain sync and so on. I

would have thought that manual override of FEC on the flash unit

itself should have worked, but I've never tried this combination.

I am just adding some precision to my question:

 

What I meant in my first post is that when the flash is mounted off shoe, the FEC on the flash seems to be disabled (while pressing the sel/set button, nothing happens. The button works just fine when mounted on the camera hot shoe ie. in ETTL mode).

So THE big question is: What do I need to do if I want to use the flah off shoe and still be able to do some flash espo. compensation?

Thanks for your answer (very interesting link...), so apparently the sheapest way to preserve all flash functions is the Off Camera Shoe Cord 2. Thanks you
