In response to Fred’s comments:
I can’t imagine using filters
on a pocket camera.
If I really wanted to use filters, to me it makes more sense to get an interchangeable-lens camera (ILC).
I don't know that there are any
pocket cameras that accept filters.
And even though I do have such an ILC camera — a Micro Four Thirds Olympus OM-D E-M5
— I still almost never
use filters. Maybe I’m just too lazy, or too out of touch of the benefits of filters, but I find that I can generally achieve my photographic goals without filters by shooting RAW images
and processing them in Adobe Lightroom,
using software filters after
taking the picture.
But if your goal is to achieve everything in camera
without any software processing, then I can see how being able to use filters would be important. In that case, like I said already, I think an interchangeable-lens camera with lenses that accept filters would be the way to go.
