hi, i have a d3100 & d5000 and want to use an opteka flash ef710dg-n which is supposed to be a i/e/super ttl flash???(dependent on which web site you look under)anyway after my last post about flashes i am now trying to figure out how to change the power/speed of my flash however there is no lcd on the flash so i assume that it is done through the camera????or is it only selected by the camera and not user adjustable????
