I'm not an expert in flash extender.. picked it up from Edmund & Darren. But I have a pix of the flash extender..Originally posted by hackie
how abt flash extender?? any DYI to show? is it for directing more light to the front so as to "extend" the flash range?
In my understanding, the fresnal lens help to focus the light into a smaller area thereby increasing the intensity of the flash at a longer range. In effect, it should help to improve your shots about 1-2 stops.
Someone who understands this better please feel free to correct me.
