I've been lucky enough to acquire an ST-E2 to be used with my Elan 7 and my 420 EX. The question I have is one that I've seen online but have been able to get a clear answer to. When the ST-E2 is being used on the Elan 7 and the 420 EX is in slave mode (as it should be), the 420 EX remains at the 24mm focal length. I'm also unsure that it's giving off enough light (I still have to run test shots as I just got the ST-E2 today) when it is fired based on what I have on the camera and the film I'm using. I know that I cannot set the focal length on the 420 EX manually - I need to get a 550 EX for that (on my shopping list) - but has anyone have any experience with this set up that can offer me some insight regarding it? ---------------------------------------------------------------------------- ----------------- It is normal to go to 24mm zoom setting on the flash. That is the way it is designed since the ST-E2 does not transmit focal length information. Doing this ensures coverage for any focal length used, but will reduce the flash output. If all is operating correctly you should have good exposure. Bear in mind, if you are testing it without film in your camera the output of the flash will be different whether you are using TTL/ATTL/ETTL as this uses the reflectance of film which is a constant v. the reflectance of the film pressure plate in the camera.
