Thanks much for the tip. Just to follow up: I've now had a chance to removed the filters and take a few shots. Without filters, no vignetting. With one filter (either one), little or none. This is really a great system and I am very happy this is resolved. Thanks again for the patient advice.
All the best.

Another question if you don't mind:
What do you mean with little or none with either one <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='' />? Is it the same fairly sharply delimited mechanical vignetting or just a slight, gradual darkening of the corners, i.e., optical vignetting (which will be worse close to infinity than close to MFD, where it likely will be invisible)?
If it is the latter, you can switch on ALO (Auto Lighting Optimizer; Custom Functions) which will get rid of vignetting in your jpegs if you shoot those or process your images in DPP.
BTW, I did test one or two 17-55s a couple of years ago, and I found it had some vignetting at 17 mm mostly, which disappeared relatively quickly for the largest part when zooming in, or when stopping down a bit.
Kind regards, Wim
