You risk vignetting (and *possibly* reduced corner sharpness)

by adding extra spacing between the lens and zoom-through

WA converter (with non-zoom-through types, extra spacing

sometimes improves corner performance, at least on the cameras

I've tried it on [many, with many converters...]). You can get most

filters in thin "gel" form in squares, and cut to size and drop these in

behind the WA converter - I do this when shooting infrared.

Dust can be a problem, though. With the HG0737, I found a Hoya

72mm circular polarizer neatly press-fits on the front (I use a few

pieces of masking tape to secure it).
