I have the Fuji Finepix S1900 (bridge Camera) with an 18X optical zoom which is very good for alot of simple photography, but the shutter speed is so slow it is nearly impossible to take moving shots. You have to move the camera with the object which is extremely difficult. Also the focus is slow on clamping on to an object so again photographing moving targets becomes difficult.
I do not know if all bridge cameras are slow, but if he wishes to take action photography you may have to spend more.
