I discovered that the lens I had was a K lens based on serial number (i misread Roland's data for AI start range) - which means it was equipped with a AI conversion kit already.  The tell tale sign of a converted K lens can be seen with the pattern of the rubber focus ring (the bumps are narrower - compare against the shape on the lens hood on the right)

I managed to finally get a unconveretd K lens with the elusive HK-3 lens hood, which Roland had mentioned elsewhere this was release for the AI lens run.  Below we can see direct side by side

Greetings from France. A quick look on your Flickr gallery shows a lot of interesting work. Glad to see people still involved in analogue photography which I have abandoned long time ago.

For now I did the safe thing: I pulled the trigger on a Z MC 105mm f/2.8 VR S Macro Lens. I Guess if I have a favorite focal length it is 105mm. When I bought my first serious camera, a Nikkormat FTN my first lens was a 55/3.5 Micro-Nikkor followed by a 105mm f/2.5.

The Z MC 105mm f/2.8 VR S is a bit smaller and lighter than the Micro-Nikkor 105mm f/2.8G VR and thankfully lacks the latter's longitudinal chromatic aberration. I consider the old 105/2.8 lens to be somewhat at the mid to lower end of a good lens for that aberration.

The new 105/2.8 is a substantial lens. I wish the girth and length were a bit less but it's not the honker that the old lens was.

I'm still considering my options for a mid range zoom.

I've got 24-70 f4, I find it very good for every day use , its small (collapsible) and light but f4 is limited to have bokeh in your photos
The 24-120 f4 is a very nice choice but again to big to carry around, I prefer my Iphone
I use my Z 40 f2 light /plastiky but wonderfull lens
