I believe the OP is using a DMC-FZ150 which has a 4.5 - 108mm / f2.8 - 5.2 lens and can close focus down to 1cm.

How thick is this DIY filter?

Hi TCav,
Well, it's basically the thickness of two polarizing filters screwed together. My calipers say 12.4mm (that would be two filters plus the space between them). I don't know what the distance is from the first (CPL) filter to the camera lens. It would be whatever a normal screw on filter would be.
I haven't tried the other suggestion yet, i.e. turning off the AF and using manual focus ....... that's next; but I have noticed that I only get the "focusing on lens problem" when I'm not using the zoom.

Hi All,
I've tried this device using MF with similar results. So.... I've decided to abandon the project for the time being. I may come back to it at some time in the future, using a better CPL, which is one of the stipulations the poster, who recommended this homemade variable neutral density filter, suggested; or ........ find the device that Simon recommended.
Thank you all for your help.
........ john
