A99 the end of flash photograpy?

The flash on your A55 has a guide number of 10 meters, anything past that and your on camera flash is completely useless. Do you do a lot of birding in the 0-10 meter range?

Its like those people at football games who have their DSLRs out with the pop up flash going, trying to take photos of the players 50 meters away....

To hit a bird with a flash you would have to have a very powerful dedicated flash unit.

Higher ISO = faster shutter speed as well.
