Hi FtwayneFish ,
I found the best way to get results from a new camera when taking fish
pics is to set the camera to automatic and continual auto focus (caf)
if you have it. turn the macro button on, (flower symbol) and use your flash
at a low setting if you can set it, you need to experiment a bit with the flash.
the flash freezes fash moving fish and you get a better shot.
For tank shots, don't use the flash but take the pics at night and turn of all
other light sources in the room.
Hope this helps, Mike
