Title: New Nikkor Thousand and One Nights article with an interesting appendix
Post by: Akira on January 08, 2026, 13:08:22

The latest No.96 story is about Nikkor-H 85mm f1.8.  And in the appendix, the auther is explaining the optical influence of the sensor filter when using lenses designed for film cameras.

This explains my disappointment in results with my 24 f2.8 AiS on a Df, a lens I was happy with in the film days.

The AiS 24/2.8 has a reputation for not doing well on digital.  I've always wondered if the previous Nikon 24mm, the K/Ai 24/2.8, does any better.
When the full frame D3 arrived, I was lucky that the handful of old Nikon lenses I happened to own at the time seemed to have had no obvious decline in performance on the new digital sensors. K/Ai 18/4, AiS 20/2.8, AiS 28/2.8 all seemed to work well on the D3.

The appendix also contributes to undrstanding why catadioptic lenses with rear filters are calculated with that glass in the light path. Something which several net post seem to believe is unnecessary. Also, the type of glass must have an influence on how different  wavelengths are refracted
