Hmm. This Leicaist (Nik(G)-L/M) Nikon G adapter looks exactly the same as the Leicaist Nik-L/M I have. Except for the letter G.

The one I have is of course fine for any Nikon mount lens with an aperture lens (such as Zeiss ZF or older Nikons).

But what is the difference between the one I have and the new one? I though the only relevant difference between a G adapter and one that isn\'t sold for G is that it would have an aperture control). Maybe Leicaist just changed the name on the adapter, without quite realising what it meant?? But maybe not, I\'m don\'t have a Nikon history...


As you suggest, the only difference between the adapters seems to be the name: Nik-L/M vs Nik(G)-L/M. Colour me cynical but I find it difficult to believe that Leicaist changed the name without realising what they were doing, given that the G designation specifically refers to Nikon F mount lenses without an aperture ring. Since the Techart PRO shop lists Leicaist adapters for 17 different mounts, surely it\'s unlikely that Leicaist doesn\'t understand the variations in the Nikon F mount. On the other hand, one product shot shows a Nikon AI-S lens (with an aperture ring) mounted on the G adapter.

Techart / eBay sellers charge $10 / $12.50 more for the Nik(G)-L/M adapter than the Nik-L/M model so there\'s at least one thing we can be sure about: you\'re paying a premium for that missing aperture control ring.


I was wrong. I should have looked at the photographs of the adapter more carefully. As jonrock points out in his later post (below), the Leicaist Nik(G)-L/M adapter does have an aperture control mechanism: rotating the adapter itself activates a bar that moves the aperture lever in Nikon G lenses.

Actually, that is what I thought of it too until I saw different angles of the adapter. However, if you look at different pictures of the adapter, there is a ring to control the aperture. It\'s just that the adapter seems to have a different design compared to any of my other Nikon G adapters.

http://www.ebay.com/itm/Nikon-G-lens-to-Leica-M-LM-camera-Ring-for-M240-M9-M8-M7-with-TECHART-LM-EA7-/291882385218?hash=item43f58bbf42:g:jC4AAOSwmLlX4jaJ

Take a look at the 4th picture in this Ebay listing. There\'s space for the ring to move. There\'s also a bar that will move the aperture lever in Nikon G lenses.


Ah, my apologies! I was expecting there to be a ring with a numerical index, as one sees in the Metabones Nikon G/F To Sony E adapter. But the 4th picture makes clear how the mechanism works: you press the silver button to unmount the lens while rotating the entire outer ring towards the button moves the bar that\'s visible in the lower right, which as you say moves the aperture lever. But how do you know what aperture you\'re setting?
