Just finalised the making of an infinity-focusing adapter for my 100mm f/1.6 Rodenstock.
The 100% crop below is of a building crane about 200m away and not very exciting as such, except this must be the first time I captured a bird-in-flight with that lens!
100mm f/1.6 Rodenstock XR-Heligon on focusing adapter, Z6. 100% crop.
Added note: Photo Ninja has still not a colour profile suited for Z6, in contrast to Z7. Thus I obviously need to make my own because the colours are off, in particular with the Rodenstock.
