    Today I got the adapter, but couldn't get it to work. The adapter won't fit on the Contax 140 mm I have. The bajonet is okay, but the lens turns on the adapter very, very tightly and it won't click in place. It will not get passed the pin. On the camera side the adapter fits just fine. The camera turns on, but does not ‘recognize' there's a lens attached. Aperture gives a — and no AF. I guess I'm going to send it back, very disappointed.

    I think I remember having read somewhere that the Hasselblad adapter is also quite tight, but that it does click in place.

    That is disappointing. This was an adapter that I was considering myself. Let's hope the replacement will work well.

    yes it is extremely tight and the button is so small that a klick is almost not noticable. But no problems so far with the Hasselblad adapter

    I use mine with several Contax 645 items.
    The fit from Adapter to Leica S2 is perfect, as with Leica S lenses – no issues.

    The fit to Contax 645 lenses and extension tubes is very tight.
    My 13mm extension tube will lock after some use of the adapter tightly into place.
    My 80/2 Planar will not lock when normally attached.
    After using the adapter now for about one week, I can attach the 80mm when twisting tightly and it will lock into place sometimes.

    As the extension tubes didn't lock the first times, I attached them but will now more or less lock, I will look into this for a while and see, if regular use with lens changes will “wear in” the adapter.

    Honestly, I did expect the adapter to work flawlessly for the price, Leica is asking for it.

    Should it mechanically wear in, it will be fine though.
    When comparing the locking mechanism of the Leica adapter and the Contax extension tubes, the locking pin of the Leica adapter does not sit as precisely in position, as the Contax locking pin in the extension tube does.

    Measurement wise, both are within ±0.03mm in Ø, while the Contax pin measures Ø 1.97mm and the Leica locking pin is slightly smaller (so it is likely not an issue of a locking pin, that is too large in diameter).

    I have another issue though with the operation of the Leica “S-Adapter C”:
    I have to nailed the exact behaviour down until now, as I was busy shooting and did little testing, but I have to regularly unmount the adapter from the camera body, as the camera (Leica S2 with latest firmware version 1.0.4.2) will “forget” the mounted lens.

    When this happens, all lens information will be forgotten and not displayed anymore on the info display.
    It will also no aperture information be displayed in the viewfinder and the camera behaves as if no lens is attached at all.

    So far, I have found during operation, that it is possibly linked to the camera forgetting the mounted lens during standby/ sleep mode, as the issue disappeared during a day of shooting, while deliberately preventing the camera from going into standby mode.
    I have to test further though to verify.

    As my S2 body suffers from a dead OLED display, I will probably ship the adapter with the body to Leica on the next occasion and have this behaviour checked out.

    Please share if you experience similar issues of camera bodies, that “forget” the attached lens, when using one of the “intelligent” Leica-S adapters.

    Btw – I love, using the Carl Zeiss lenses on the S2 so much, that I have shopped around for some of the interesting Contax 645 glass – such a great glass to have next to the S lenses, both in focal length options and in different imaging character!

    Sorry to hear this. I hope Leica can sort out these issues because I really like the idea of adapting lenses on the S system. But for €1729,- I would expect an adapter to work flawlessly.

    After 3 weeks I'm still waiting for a replacement, mine was DOA.

    I have now verified that the issue of the Leica S2 + Contax adapter “forgetting” the mounted lens is either an issue of the Leica S2 or the adapter itself.

    The problem is triggered 100% reliably when the camera is activating the standby mode.

    Regardless, which Contax lens I have mounted (80/2 Planar, 120/4 Macro, 140/2.8 Sonnar, 210/4 Sonnar, extension tubes 13 and 26mm), my Leica S2 will reliably forget that a lens is mounted.

    The only remedy to this problem at the moment is to unmount the Contax adapter from the S2 body and remount it.
    The Leica S2 will regain all lens information the moment, the adapter is remounted immediately and will work flawlessly as long, as it is prevented to go into standby mode.

    This includes even camera off/on switches!

    If I prevent the camera from going into standby mode and switch it off and on again, it will still have the correct lens information.
    If the camera has been going into standby mode and is then switched off and on again, it will still be inoperable and have no lens information until the adapter is unmounted and re-mounted again.

    This is either an issue with my Leica S2 + Contax adapter or a firmware related issue (both camera and my Leica S lenses are running the latest firm ware updates. My Contax adapter reads a later version of the lens firmware than my S lenses!).

    Just a quick update: the second adapterI tried had exactly the same issues as menos describes. This made me reconsider my purchase. I've sent the adapter back for a refund, obviously there are adapters that work flawlessly, but you know, twice bitten … I cannot work with an adapter that is unreliable. I'll stick to S lenses for now.

    This was exactly the problem with my Hasselblad adaptor … The lense was forgotten after the camera switched out. The replacement behaves perfectly .. Thankyou Leica
