Hi all! I shoot with the above. My question is this:with the 1.6 crop factor of the 300d Rebel should I be setting the flash zoom to one step greater than the lens zoom? I can do this in the manual zoom feature of the 500 Super, but don't know if I should. It makes some sort of twisted sense to me, but probably is nonsense. I appreciate your opinions here as I've learned a lot. gary

sorry, i cant answer your question, but on that same topic, does the new canon 430ex speedlite incorperate this feature (flash understands that the image will be cropped).

That's correct by doing this you should be able to pick up some extra distance since the beam is now more concentrated...

OK NHL, great. But, can I still shoot in ETTL mode when zoomed? In other words, I'm not sharp enough to get very manual with this flash. It's gotta do most of the decision making for me or I'll screw it up. Thanks. gary

Yes - ETTL all the way :idea:

-> You'll know when you've zoomed-in manually too much when the light start to fall-off around the corner on your image

This only happen @ the wide setting - Anything above 105mm then you don't have to worry (free GN upgrade )

Thanks NHL (as always). I'll experiment with it to find the optimum zoom and go with it (at least on the 85mm prime). Could be a little harder on the 24-70 but still doable. gary

You don't have to worry on 85mm prime and longer :idea:

The 70 is already @ 112mm (1.6x70) - the max zoom position of the 500DG Super
-> you might try it with the diffuser panel (@ 105mm as well) for the 24mm or in between position... to keep the higher GN
