You'd probably be better off with a 2" LPF like a Lumicon DSF when you use the camera at prime focus.
I had been wondering about vignetting with clipin front filters and so not bought one yet.
The 70-200mm has quite a wide cone at the image plain, I want to get a 70-200 f2.8 L IS with the AUD is right , did you see the same effect at longer focal lengths ?
I don't fancy buying a
LPS-P2-82 at 349.00usd , the idea of these dropins (front filters) is to not need a different filter for different EF lenses.
