I bought an old SB-24 for about $40 after reading all the stuff from the Strobist. Being kind of a DIY-er I figured I could handle being a little low-tech and using the manual settings to get the results I need on my D70 shot in M mode. The flash works fine, but not always. The LCD and buttons all function and all the modes work on my old N70. With the D70, however, sometimes the flash seems to lock up and no buttons work, even in the flash's Manual mode. If I remove the flash from the body and turn it off and back on, sometimes it works. Occasionally, the buttons just start working while attached to the body. Anybody know why this would happen? It seems to be a function of using on the D70, not the flash itself, since it works on my old 35mm body just fine. Is this a sign that I should just go buy a cheap SB-400 and move in to the iTTL era?
