Some of those smaller digitals are not so good for fast action shots as such, and the devil to hold your frame when trying to shoot a moving target as such.

Nice images here also.
Gary Cooly a pro photograher here has some amazing shots taken a few years ago, but guess what he cannot sell them as persons do not believe that the fish are actually doing that.
He has some of 4 and 5 fish airborne.

Granted it is not something you will see Brown trout do that often.
Sea trout which are a anadromous Brown trout will do all they can to move up stream with very little water..
I used to watch them back in the UK. They will run sideways over shallow shoals to find the deeper water above, such was the urge to find the spawning grounds.

Salmon will do like wise.
