Hey everyone!
Just curious about flash photography with my 300D. I know the 550EX & the Sigma 500 Super offer E-TTL compatibility. But what about straight TTL flashes? Has anyone tried these? What sort of results did you get? What features did you miss by not having a flash offering E-TTL?
Thanks for the info! |

If price is a concern, why not the 420EX speedlite? With the $15 rebate it is the same price as the Sigma 500. I picked up the 420EX for my PowerShot Pro1 and the results are amazing.
Good explanation of E-TTL, A-TTL and TTL
Some good reading about E-TTL |

Thanks for the info AW.
I've considered the 420 but it seems to be lacking in the manual feature set. |

Biggest issue with using the 420EX on the rebel would seem to be the lack of flash exposure control on the rebel.
If you use a 550EX you can at least dial it down on the flash unit. If you use a 420EX on a 10D/D60 you can dial it down on camera, but from what I hear the rebel doesn't let you do that.
I almost always use my 420EX with TTL, but dialed back to -1 & 2/3rds FEC to try to give more even/less noticeable fill flash.

So you disable the E-TTL feature? |

I disable auto fill reduction and just dial it down. Seems to work quite well, though I'm by no means experienced with fill flash.

Gordon by Dialing back (and FEC) do you mean the Flash exposure compensation?
I've been running Flash Exposure Compensation with my 420 at -2/3s on the Pro1.
Sorry, I'm a noob to these new fangled flash units, in the old days a bright light went off and everyone closed their eyes when you took the picture. Now I hear whirling in the head of this thing as it zooms in and out, lights Dancing across the back of it, and the camera changing settings all on it's own. I need to read about the FE Lock feature on this thing. Actually I use mine for fill as well, bouncing it almost 99.7% of the time.
I may want to drop to -1 2/3's as well as this thing is still a little warm indoors.

Tell me about it! In another thread, the fact that some older flash units could fry your camera was discussed. I'm sure glad I learned about that!
But what about with a 'hacked' Rebel - you should be able to have more control of the flash that way, yes? |

Yup - that's what I mean - slightly more control than with the 'auto fill reduction' enabled, and using flash to just raise shadow values slightly, rather than provide the main light source, I've found that the
-1.66 EV value gives generally good results (based on something by Galen Rowell that I read). Though the whole (E-)TTL operation is a bit on the mysterious and quite complex side to me just now.
