G1X + 250D = Blurry Pics? ☆ NO !!! (PICS)

Canon have a very long history making lenses. They even supplied Nikon in the early days when it was called "Kwanon".

Their lenses from early screw to today bayonet are as good as you can get.

Sooooo..I don't see why their filters should not be just as good as their other lens optics. His Canon filter is just right esp on a Canon lens.
