Vignetting with FA 31 Limited

Some of my recent shots with the FA 31 showed some small vignetting, and I am assuming it's because I had too many filters on it--the UV I forgot to remove, a polarizer, and a red 25. Has anyone else ever had this problem, and am I right in assuming two filters is the limit?

I've not noted the characteristic myself. I recommend taking off the filters and try a shot wide open against a white wall, then you'll know if your copy is sound.

Stacking filter is not recommended since it introduces light fall-off, degrade IQ, and the setup is prone to flare. Most of the time, two would be the limit (same with Cokin P set up).

Unless you've got a really wide step-up ring. But polarisers get expensive then.

Yep...sounds like too many filters. I think you already solved your own problem, though. Remove the UV if you're going to be using two filters.
