The problem I'm having is that many of my pictures are out of focus. I'm thinking that the focus light would greatly help in this regard. Also, I think I'll get better light balance using dual rather than a single strobe.
I'm not totally happy with the Ikelite housing. The wheel and plastic ring for adjusting the zoom is not the greatest quality and I've had problems with this since day one. So, if I decided to go with a new housing, my thinking was that I would upgrade the camera at the same time.
Or, I could get a better dome port and zoom control for the existing Ikelite. In any case, I'm also looking to get a better Macro and wide angle lens. I could certainly do this with the existing Rebel / Ikelite set up, and get new dome ports for the new lenses. Maybe the zoom aparatus from Ikelite has improved over the past few years.
Thanks for your reply to my posting!
