View Full Version : BIF and C. Poliz.?

Is anyone using a drop-in C. Poliz. filter when doing birds in flight? Part of says I cannot afford to lose the light. Part of me says there might be some impressive results if used at the right angle on a clear blue sky background. I know it wouldn't hurt to have a C. Poliz. in general for my 300 and 500, but it does cost a bit for how often it might prove handy.
