A B&W 'EW' version (ExtraWeitwinkel/ExtraWideangle) will also prevent
vignetting (but not offer a secondary screwthread either; I believe
only Heliopan does (and only Heliopan offers 'calibration' (numbers
on the rim to indicate orientation of the filter, for those with
viewfinder camera's and a second 'viewfilter')).
