It's 20 (in metres) hece the name (65 in feet). But if you clip on the wide angle diffuser, for lenses wider than 35mm, then it drops down to 14m.

Issac, welcome from me too. Your "teacher" is talking complete nonsense and should be taken out and shot. However if do you want a more powerful flash, you should look for a Metz gun with the Leica adaptor. By the way if you are keen on flash, get yourself a Nikon SC-17 cord that will allow TTL operation off-camera. Regards, Bill

Re: Flash SF20 unit
Isaac, I agree with Bill - your teacher is talking nonsense. A guide number of 65 feet means that with ISO 100 film, and an f/2 lens, you would have a maximum flash range of 32.5 feet. With ISO 400 film, it would be 65 feet. Not at all useless in my book!

Re: Flash SF20 unit
Does it not depend upon what the teacher wants them to do with the flash? If bouncing flash is necessary, then the SF20 is not really the best, for which the Metz systems are better. However, for straight flash, I agree that the SF20 gives good results and even with a diffuser is good enough.
