Yes of course. For some uses there is no chance to put the eye at the eyepiece and thus there is a need for such optical sports finder, but with macro work and such it is "just" a matter of comfort. And a right-angle finder can still be used facing upwards when the camera is in portait orientation. Not all optical sports finder that can do this.Of course with right angle finders, you have to put your eye right up to it while the action finders are intended to have your eye much farther away.
