I have a Fuji W 125/5.6 that I got because I liked the field of view and it can stay on the Wista when I fold it. So ideal for going light.
But this week I had it along with the just arrived CM/W 256/6.3 and I immediately notice a difference in "clarity" on the ground glass. The 250 is very visibly sharper, clearer, easier to focus etc. Now I took a better look at the 125 and what I saw was this:
This doesn't look good. It looks far worse on the photo but I had a hard time getting it visible in the photo. I took the rear element apart and it is on the last cemented doublet. I cannot make sure if it is on the most rear surface or (worse) in the cement. I tried cleaning with alcohol and a microfiber cloth. And even with an ammoniac/peroxyde mixture but no change.
Any idea what this is? It doesn't look like fungus, I cannot see it as scratches either.
