I'd heard of K&F filters, and I'd seen some rather glowing reviews. When I had a chance to try these for myself, I jumped at it. And I was NOT disappointed.

I tested these against two other brands, both of which cost north of $200 for an 82mm size. When I was done snapping photos in a park under a mid-day sky full of puffy white clouds (a perfect sky to test a CPL), I went home to see how they measured up.

My first clue was mistakenly thinking the images from my Breakthrough Photography filter were the ones I took through the K&F. The other, the one that boasts there is absolutely never in a million years chance of any hint of a color cast, has a slight but definite color cast. Yes, of course I took control shots without any filter. The other, a B+W, was the same as this K&F -- but it cost a bunch more.

I should note that these were all high-transmission filters. If I need an ND I'll use one, thank you very much. No need for a CPL to try and double as one.

Bottom line is these are very good filters, as good (or better) as much more expensive brands. That makes these not only a great value, but a smart choice.
