Hi all, I'm trying to source the rear filter holder of the Panasonic 8mm fisheye lens to fit to my Panasonic 7-14 zoom to cure the "purple blob" issue. I've contacted Panasonic in the UK and they put me onto DK Audio Visual who are asking me for the serial number of my 8mm lens to confirm the part number. I don't own the 8mm and am unable to give them a number. My question is can anyone either forward me the serial number of their 8mm lens so I can pass onto DK AV, or if you've sourced the filter holder in the UK, where did you get it from and what was the part number? thanks Steve PS I did provide DK AV with the VXQ1911 part number but they want to confirm that that is the right part.
