So as a newbie to the Nikonians I've been trying to catch up with how other shooters are using the Nikon CLS system. I ve spent all weekend reading every thread that relates to my field of photography. I let go of my studio lighting a few years ago when I moved to California from Oregon. Here I don't have much call for it. The north state is a studio to itself. But now a lot of my brides from the last couple of years are having babies and I found myself doing infant and maternity shoots. I've been using natural light when I can but have found the CLS to be fantastic as a mobile studio. BUT after reading through this thread it seems the question that hasn't been answered or I missed it is.....Some of us still have older flash units that we've never let go of. I've got a DX50, a Vivitar 285, and a bulb style slave with the screw on filters (I think it's Morris super slave). It seems a shame that they can't be used at least for fills or highlights or something. Or do we just set them free to rome garages and attics and storage units.
