I had bought the original Mecabounce 58-90 and cheaper Delamax diffuser for my 48AF1. Both are neutral in color (as long as the reflective surfaces in the room which also are), with two works, the TTL metering (with my Olympus E-3) properly. The Delamax but brings much softer, much more comfortable for my taste light. Clear light is much softer if the bouncer is on it, but the mE hardly less effect I achieve by folding down the built-in flash diffuser. The Mecabounce Although I have never lost, but always used with a bad feeling, because it at least gives the impression of sitting not quite fixed. No musthave!
