Hello I am a total newbie to Uw Photo I have a Ikeilite housing with a cannon a570is camera. I Have a friend who is selling a Nikonos SB-105 strobe and will sell it to me for 100 bucks. will it work with my setup that I have now?? I have been hearing stuff about TTL's and stuff and I am not sure what that is. If I could get any help I would greatly appreciate it thank you
