I created the rough texture using the Wings3D shaders. Then, I used the Gimp to create the base of bump map, added the grip's pattern and this way I created the normal map which gives this slight deformed surface we see in some lens filter.

Here is a closeup of the final result (basecolor+rough+normal):
