Hi,
By the time I upload this message to the mail server the following will
probably already have been mentioned, but...

I presume the vignetting to occur especially when shooting in the wide-angle
range. The name already says it all: "wide angle", this then means that the
wider the angle the more likely it is that vignetting will happen. For the
50-70mm range I wouldn't expect much vignetting, but between, say 28-40mm
it's much more likely.
I have a Hoya Vario Cross filter which is *really* thick, at times it causes
some vignetting with the 35mm shift. I haven't tried it yet with the 24mm
and 28mm lenses, as I fear vignetting will be too much.

The best I can suggest is: the wider the angle, the smaller the amount of
used filters should be.

Except for the last one mentioned I don't expect many vignetting.
Ah, this brings me to an interesting point, does anyone know if vignetting
will occur on the 24/2.8 when used with the hood for the 28/3.5 ?
Cheers!
Olaf
