  1. Before upgrading equipment I always ask myself "What is lacking in my current setup that I really need to do my work?" What do you feel is lacking with your present camera? You mention sharper pictures. Are you not getting sharp photos with the Rebel? Perhaps a technique, lens, or post-processing upgrade would make more sense? That said, I love the 30D...
  2. There should be an optical slave trigger built in to the alien bees, right?. I think you can use any dumb manual flash unit on-camera (Vivitar or whatever), dial it's output way down, and use that to trigger your bee. In other words trigger wirelessly using light, not radio.

    Does the alien bee manual discuss optical slave triggering?

  3. Three additional points to keep in mind which complicate the answer even more:

    1) The center focus point is the most sensitive one, so in low light shooting using other focus points may be more difficult.

    2) If you set the Custom Function to use * for focus lock, then you can't do Flash Exposure Lock (FEL) with * unless you reset the CF. Kind of a pain.

    3) If you use spot metering mode in camera, the meter spot is always locked to the center focus point.

  4. Correct me if I'm wrong, but FEL only uses the middle focus spot. So you can select any active focus point you want and it won't affect FEL. Choose a focus point that after recomposing will fall on your subject. Just remember when doing FEL to have the center focus point on the subject even if it is not your chosen active focus point. And be sure to be in One Shot AF mode.
  5. I am by no means an expert, but here are my thoughts. Question #1 - yes, the camera/flash will figure what it thinks is the correct exposure. This assumes the flash is in an auto mode, and you probably need to research "flash compensation" and "flash exposure lock" in order to master using one flash correctly since these two items can have a huge effect on how your image turns out.

    Question #2 is more complex. Your camera/flashes should allow lighting ratios to be set. Research "lighting ratios". But Canon ettl is more complex. Traditionally a photographer thinks of lighting ratios on the subject of interest. With a background flash I think the camera can only determine ratios based on what light comes back into the lens. This is not necessarily the same ratio of light as on the subject. It will really depend on the slave's angle, background reflectivities, and lots of other variables and my very limited experience says that is hard to control outside a studio setting.

  6. I'm not familiar with the RebelXT, but a used Canon 420ex flash should only be about $125 (very nice flash - I have two). Or an inexpensive Vivitar (or similar) flash run in a strictly manual mode (but you'd need a handheld flash meter to get correct exposures).
  7. If the bright white autofocus assist light of the Elan7 would bother you, try the older ElanII which has a nice, subtle, yet effective red focus assist light in the body. No doubt the Elan7 is a great camera, but I prefer the ElanII.
