I can’t get my head around this part of the instructions. Can anyone unfathom it?

Will someone correct me if I'm wrong: I believe this instruction applies to AI and earlier Nikkor lenses while not applying to AIS and later Nikkor lenses. I should know. Perchance the AIS Nikkors had linear apertures for the Nikon FA's exposure system?

A lot of the candidate lenses for this adapter have non-linear apertures ....

I've ordered one for potential use with 1-2 non-CPU enabled F-mount lenses. Should arrive later this months if international transportation still functions.

Blimey, about ¥3000 more on aliexpress than directly from Shoten here in Japan!

Yes, I am surprised how good the wide-open performance of the lens is.
When I got the Plena I went to an old factory building close to where I live to take some pictures but I forgot the narrow angle of a 135 mm lens so it was a bit of a challenge.
The building was first a Piano factory (Søren Jensen) and later factory for the Penol brand pens (Christian Olsen).

Building here at 2nd page (how it looked many years back):

Here how it looks today through the Plena.

Interesting possibilities!

   Yes Fons, I think so too. Here another example. 90 degrees, looking straight down from the drone. There are many interesting things going on  :)

I finally managed to service my copy of the 20mm f/4 - and I had a much tougher time than Ric.  Experiences shared

https://whatdoineed2do.blogspot.com/2026/01/widely-regarded-nikkor-20mm-f4-ai.html#servicing

Servicing this is an utter pain - i've had 2 copies of the K (103xxx and 106xxx serial numbers, with Roland data saying the first one was 1030001) and they're both sealed so well its like they didnt think these lens would need to be ever opened again.

The focus ring retaining ring does come off and I had to file slots behind the ring to get to the focus ring screws and the lens objective needs the strength and torque of all humanity to unseat. BUT its done - i finally got in and was able to save these 2x lens from a life in a junk bin.

TLDR: its hurts, dont do it unless you have the tools and know exactly what you're doing - you'll damage a beautiful little lens and its not worth it
