Hello fuwen!
1. I didn't try using a filter with it...........so cannot comment
2. I suppose that the reason should be due to the lens as a 500mm tele lens!
A 1 degree spot meter should be still relatively much "larger" than the spot meter area of RTS III, imagine that it is a spot in a viewfinder of 500mm.........
Thanks wah!
I would expect filter to degrade the image quality a bit but this is my first experience of filter causing inability to focus at infinity.
As for the metering will try to do more comparisons.
