IR filters
« on: December 05, 2012, 10:00:30 pm »
hi
does anyone know whether it is neccessary to use Infrared and or UV filters with the 428EX. If the window covering the CCD lets IR pass, then I thought filters might be needed.
If the answer is that filters are needed, how much difference do they make.
