I'm trying to mount a filter onto a 58mm Super Angulon XL with the Schneider 3B center filter. The CF has a front thread of 86mm.
B+W makes a glass screw in filter that I could use (092 EW--for infrared), but Schneider told my that they haven't sold one of these in two years and that a 6-10 week wait is "reasonable."
So, I'm looking for some other options. I saw this page:
and might have SK Grimes make an adapter so I could use 4x4 filters. Are there any other options?
The filter I'm going to use is completely opaque. I also don't want to mount the filter on the back element.
