First impression, handling and size reminds me a lot of the W-Nikkor-C 2.8 cm f/3.5. Aperture clicks are firm but aperture setting is quite easily altered when using the knurled front ring for focusing. Reminder, only use the infinity lock lever for focusing to avoid this. Focusing is very easy and stays as set. Regarding size, the lens fits perfectly on my screwmount Leicas, that's why I bought this version of the lens. I have also tested it briefly with the Xpro3, where the FoV corresponds to a 42mm lens, no photos to show here as of yet.
Below is a quick test shot on film (taken at 1/30s f/2.8), expired Neopan Presto (400PR), developed in Ilford ID-11. Scanned with Nikon Z7II & Micro-Nikkor 55/2.8 on extension tube, Intrepid enlarger head as light source and converted in Lightroom Classic using Negative Lab Pro.
