Last weekend, I was at my sister's to photograph her cats and kittens. A friend of mine lent me his portable kit consisting of 2 of each SB-28, lightstands, cactus triggers and umbrellas. I'm thinking about seting my own kit myself and I'm wondering which of the SB-28 or the SB-80 I should go after for this kit ? I know the basic features of both but I am wondering if some features from one model are more desirable than others. My budget is limited so that's why I'm not looking to go with CLS and SB-800's and SB-600's though I currently own an SB-600 and intend to keep it. I've thought about the Vivitar 285 HV too. It is really a workhorse but I find them less flexible than the more modern Speedlights. So what do you guys think. SB-28 or SB-80 ?
