I don't have those, when I got my cameras they weren't available, but I understand that the ones they have produced for the 119 also fit the 118, so I might invest in one for the front, I seem to get a lot of reflection in that one. Not quite so much from the rear, although it is still noticeable at times.
I am not sure how these would affect night time use, I don't want to be having to remember to put them in in the morning and take them off again at night. I see from the reviews that the a119s has better night vision than both the 119 and 118, so maybe it's not as much an issue for that camera.
If you do get the cpl let me know what you think.
