I ran into the same vignetting issue upon first using the Milich CV15 filter holder.

I had read that various prototypes of the filter holder were constructed and tested to find the best possible shading protection before introducing vignetting, resulting in very tight design tolerances.

My main need was to have a more effective lens hood that would help reduce the amount of flare I was experiencing in conjunction with the use of my handheld flash. Therefore, my initial use was without a filter attached. As such, I noticed that the filter holder does not sit without some give and wobble as the contact with the lens is at the tip of lens’ own shade petals.

With a filter attached, the Milich holder makes a much more rock-steady connection since it is now the base of the attached filter that touches the lens. No more wobble and, for me at least, no more vignetting and of most significance no more lens flare.
