Hi,
I just received a Fujinon-SF 180mm Lens, complete with both discs, red and yellow. I found instructions for it on the internet. Unscrew the front element group and push fit one or the other diffusion disc to the rear of the front element group. Replace front element group and take pictures using color coded f-stop markings. Simple enough. But the discs don't fit. I measured where they would appear to fit and that part of the front element group is 38.4mm. Discs are 32.9mm outside diameter, approx. 31.7mm ID, where they would push on to the rear of the front element group. First time I have ever used one of these lenses. Am I missing something or do I have the wrong discs? What would these discs fit if they are not for the 180mm lens. Any help much appreciated.
Thanks,
Bruce
