    PhaseOne - Leica S adapter: Unfortunately impossible because the flange distance of PhaseOne is much longer than of Leica S.
    Only Alpa or Bo Ming (Conurus/Metabones) could consider to make a Leica S - Canon EF adapter with autofocus and auto aperture to use on Canon, FPS and Hartblei cameras.

    Re: Contax 645 Lenses on Leica S

    I think this is turning around the concept of providing these fully functional Leica adapters.

    Leica is slow on delivering S lenses as it is, but seem to do okay making the camera itself. The adapters allow other systems users to either make the transition by using their existing lenses, or to get a S camera to back-up their MFD camera with one that uses their existing lenses while providing a different type of camera.

    It'd be kind of interesting if Leica announced a fully functioning M to S adapter to use some of the Schneider CS lenses ... I can say from experience it was nice having a different camera type to use in conjunction with my H4D/60 big gun ... using the same H lenses and HTS/1.5 Tilt-Shif Unit.

    However, it is understandable, however unlikely or even technically possible, that some folks would like to bolt the S lenses onto their big gun ... they ARE that deliciously good

    Re: Contax 645 Lenses on Leica S

    Interestingly, the adapters to use 3rd party lenses is not new to the S. Leica made a variety of adapters for their S1 (although for that a mount was not standardized like the current S).

    Also interesting is the camera registry. It appears that it is only ~50mm. Not far off from that of the abandoned Leica R (48.5mm).

    That's right Vivek, especially the longer R lenses. There's in interesting thread here:

    Then, it's possible. If Phase One had a shorter flange distance, it would have been impossible. The camera with the shortest flange distance is the on that can be adapted to the most lenses, ref Canon EOS.

    One of the most interesting options is to adapt the R modular 1.4x and 2x focus modules to S2.

    I had used a Kapture group Leica R to Contax 645 and used with my complete Modular system. The image circle was fine for the P45 (crop 1.1) but vignette badly on the P65 So I got uninterested (Plus I had to make a 28" long optical bench to keep the lens, focus mod, camera back in line and locked together.)

    It worked but not well enough.

    Then David Farkas asked for one of the combos and his machinist did an S2 mount (involved repositioning the aperture rig!) But wasnt too expensive, and I ultimately had David find buyers for all My stuffm (if interested see David writeup in the RED DOT forum)

    So, can be done, but needs machine work. In the end, the S2 sensor is more than cobvered by the Moduoar system.

    Anybody willing to hack $10-20,000 lenses up to change mounts is welcome to try LOL

    But actually, the results are impressive. Otherwise, just yuse the 400/6.8 and Visoflex on a M9...almost as good.

    Regards

    Re: Contax 645 Lenses on Leica S

    I am planning to try the adapter with the zoom 45-90 and eventually the 80/2.0.(Not sure if it makes sense for someone owning the70mm - but I am interested if there is a different character.) Is the 80 Contax smaller than the 70/2.5? I hope so.
    I would also be interested to check out a 45 or 55mm.
    I will report back as soon as I have some results/impressions.

    mark, leica now has a big stock of leica s lenses (not cs) that they are dumping under code u or something. i have verified this.


    i really don't understand the point of S-C adapter. for a pro there is no support of the contax lenses.

    I'm sure that a good number of the S lenses being offered are the recent trades for the CS lenses under the swap deal Leica offered early S2 adopters. I turned in all 4 of my S lenses for brand new CS versions for the retail difference. I can say my S trade-ins were absolutely mint, so someone will get some very nice S lenses for a very good price

    Perhaps the interest in CZ645 lenses comes from folks with Contax 645 systems and a bunch of lenses? Maybe some will want a few of the CZs because of the character of specific lenses in that system ... or for a missing focal length in the S lens line-up, or a performance attribute: (while the S120/2.5 Macro is excellent, it only does 1:2, where the CZ120/4 does 1:1) ... so it just depends.

    For me the adapter is interesting because I can expand the possibilities of my S2 with a 35 or a 45 and a 120 or 140 for less than 4.000,-. Do I ultimately want the Leica lenses? Of course, but this option might just get me through the coming year or so. There are quite a few mint C645 lenses available.

    Please tell us more about the 'code u' lenses. Where can we find them?

    This is true. But it might make sense to adapt the 120/2.5 Leica macro to a camera with a longer flange distance...it only makes it "more" macro! Of course, you do lose the infinity range.

    ... theoretically yes, but the lens has an floating element which would be used incorrectly and therefore diminish the IQ a bit if the lens is mounted further away from the sensor than planned by the lens designer

    Which I guess is why Leica has said there will not be any extension tubes for the S120 Macro.

    I wonder if they will ever make a S120 Elpro like for the R100/2.8 Macro?

    They have made one expressly for the 180/3.5 ... so it should be possible I would think.

    I've found a 45 and a 140 I'm going to take a look at. They're supposedly in mint condition, price 500 and 675 euros respectively. Are there any caveats with these lenses I should watch out for?

    I don't know any caveats with any of the CZ 645 lenses...

    Re: Contax 645 Lenses on Leica S

    Hi,
    I have the adapter in use for some days now and have to say that I am very pleased with the results. I added some quick shots with the 55 and 350 mm Contax lens on the S2. there are full frames and about 100% crops. Please don't punish me for the images, they are only test shots. By the way, it was a very hazy day today when I made the picture of the tv-recover mast.

    Best regards

    Wolfgang

    It is in the same range as on the Contax, by far fast enough for landscape, slow for fast moving objects, but when it locks, its 100%.

    Re: Contax 645 Lenses on Leica S

    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 thight, but that it does click in place.

    Re: Contax 645 Lenses on Leica S

    My first reaction to the new adapter was to immediately order it from my preferred dealer!

    I bought a second hand S2 a few months ago, added a new 70 Summarit-S and started to adapt manual focus Mamiya 645 lenses and my Hasselblad V lenses.

    I now have added also a 35 Summarit, which pairs fantastically with the 70mm.

    The CZ glass though on the other hand provides a huge range extension in focal length for very little money (compared to the Leica S glass) and a few lenses are really, really interesting for their beautiful character).

    I absolutely love the 120/4 Apo-Makro-Planar - it is a wonderful lens, but as mentioned before a bit tricky to focus correctly.
    I find the focus action from infinity to ~2m very fast for a manual focus lens, hence difficult to focus spot on quickly.

    The 80/2 Planar is indeed a lens as full of character, as my much loved Noctilux f1.
    I love this lens on the S and much prefer it's vintage rendering over the perfect imaging of the 70mm, when people are involved.
    I like the 80/2 Planar a lot better than the Mamiya 80/1.9 - the Carl Zeiss lens has a much more pleasant, smooth out of focus rendering and is much sharper from wide open.

    The 140 Sonnar is a tricky beast - it is very weak wide open (loaded with colour aberrations and flares easily), but it is indeed beautiful for portraits from f4 on.
    When AF is a must, as you shoot less formal, faster paced portraits, this lens, slightly stopped down is great, but it never beats the beauty of the 120/4 Planar, if you have the time for manually focussing.

    The 210 Sonnar is a sleeper.
    I received mine Today and first quick test shots show, that it performs visibly better from wide open than the 140 Sonnar.
    I was surprised, as of how well it actually works also with the 1.4x Mutar tele converter, once stopped down a bit.

    This looks like probably the most interesting longer lens option for the Leica S.

    most impressive: 120 f4 Apo-Makro Planar
    most character: 80 f2 Planar
    worst performer: 140 f2.8 Sonnar
    must have item for any of the above lenses: 13mm extension tube


    I have one issue with the adapter so far:

    If the camera is on and the adapter and lens are freshly mounted, everything works as it should and the mounted lens is properly recognised.

    Once the camera activates it's standby mode though, the S2 immediately looses all lens information and acts, as if no lens is mounted.

    I have to slightly ,unmount and re-mount the adapter to the S2 body to recover.

    The issue is new to Leica Solms and no remedy is known as of yet.
    I am on the latest firmware updates.

    I would be interested, what others experience with the new Contax 645 adapter.

    Re: Contax 645 Lenses on Leica S

    Tested the adapter today.

    Overall impression is extremely positive. Tried the 35, 45, 55, 80, 120, and 210 Contax lenses, along with the zoom; AF is accurate and AF seemed more certain of itself. Less hunting and adjustment than I'm used to when shooting a 645. I hesitate to say 'faster' but it did seem that is the case.

    One thing to note: do NOT mount a 645 Hartblei lens, the bayonet release notch on those lenses is 'deeper' than on the Contax lenses and the lens will NOT release from the adapter. Had to disassemble the adapter to remove the lens. Looks like a small mod to the Hartblei bayonet will rectify this.

    Tested the Macro with the split image S2 focusing screen, which is fantastic. The split image/microprism is great with the wonderful S2 viewfinder.

    Next up: testing to see if the standby mode issue happens on this camera too.

    Re: Contax 645 Lenses on Leica S

    Monza, thank you for testing!

    Could you please verify, which firmware versions you have displayed for body and lens, when the adapter is mounted?

    My S2 reads these firmware versions:

    if the adapter is mounted but not recognised:
    body: 1.0.4.2
    lens (Contax 645 adapter): 0.0.0.0

    if the adapter is mounted and recognised:
    body: 1.0.4.2
    lens (Contax 645 adapter): 135.4.0.0

    The safest way to reproduce the issue with my S2 + adapter is:
    - switch the camera on
    - mount Contax adapter and Contax lens
    - verify, that the adapter and lens is properly recognised (focal length and aperture is displayed on the rear LCD)
    - let the camera sit longer than the dialled standby time
    - wake the camera by tapping the shutter release button

    … voila - the adapter and lens went invisible - no more focal length and set aperture displayed on the LCD. The camera will behave exactly as if no lens is mounted.

    I talked with a customer service tech about this issue and it was unknown to them.
    As my top LCD is one of the bad batches and has failed some time ago, I will send my body and adapter in on the next occasion to have this sorted.

    Re: Contax 645 Lenses on Leica S

    We performed that same test but when the camera woke up everything still worked perfectly. I'll check on firmware revs...

    It's a fantastic combination. It's like the Leica is a native system for the Zeiss lenses. The only difference is using the dial to change aperture...

    Re: Contax 645 Lenses on Leica S

    Thank you for confirming Monza.

    Is your camera a S2 or the newer S model?

    I absolutely agree regarding the new adapter and possibilities.
    I am new to the Contax lenses (I specifically bought the adapter to expand my lenses for the S system, now starting to explore these lenses).

    The Autofocus with the Contax lenses is indeed very usable, but it is nowhere near as fast and assuring, as the AF with the Leica S lenses.
    With the Contax lenses there is before locking focus often a slight back and for in the finest increments, to find perfect focus and lock, while the S lenses simply … lock.

    I am absolutely delighted by the different, more classic rendering of the Carl Zeiss lenses. The 120 Apo-Makro-Planar is indeed one of the few lenses that really stand out.

    The 80 Planar indeed provides a look to the images, no other medium format lens provides and the longer lenses, like the 210/4 Sonnar (especially combined with the 1.4 teleconverter) expand the range of the S2 in a very compact and carry able fashion).

    I am very happy so far (apart from the little gremlin there is).
    The adapter is worth every bit of it's high price.

    S2

    This system is solely Contax, no Leica glass.

    S2 was a factory demo, and the entire set of Zeiss glass plus the adapter was less than the cheapest Leica lens.

    Re: Contax 645 Lenses on Leica S

    Just received my adapter C a week ago, and tested with all my Contax 645 AF lenses without the issues mentioned above, ie. lost information when woke up after sleep mode etc.

    Camera is S2 about a year old, all lenses are from my previous Contax system. I tend to think Leica might have reacted to the feedback and shipped now the adapter with updated firmware.

    Very happy with the adapter and the lenses worked on the S2 perfectly.

    Re: Contax 645 Lenses on Leica S

    Hi everybody, I have a question for Leica S - Contax 645 users.

    Do you received a set of Lens profiles for Lightroom to correct the 645 lenses?

    Are they available on the net? I'm using Contax 645 and P65+ back and it will be really useful to use them on LR as I'm doing in Capture One.

    Thanks! Regards

    Rob

    Ciao Roberto,
    my recommendation is to download the Alpa lens corrector plugin (free of charge) for Photoshop and Alpa provides lens correction profiles for many lens/camera/back combinations incl. for the Contax 645 lenses with P65+ back. Works well.

    Thank you Christoph,

    yes I'm using it but sometimes I got my agency to request LR catalogues with corrections applied and it will be great to have them too.

    Regards

    Re: Contax 645 Lenses on Leica S

    Currently they are not available in Lightroom, but Adobe did supply these profiles for Hasselblad H lenses, when Leica introduced their H lens adapter.

    We might get the Contax 645 profiles at some point or not …

    … meanwhile you could help yourself and create for each different Contax 645 lens a correction setting via the lens correction tab and safe it as a profile.
    It is fairly quick to apply in batches, when using the Contax lenses on a S body (exif data is supported) - I don't know, if you get exif data recording the lens information for easy applying of profiles.

    Adobe didn't provide H lens profiles when Leica introduced the H to S adapter. Leica did ... it is available for S2/S2P/S system users in the Registered Leica Owners Area as a download plug-in for Lightroom 4 and Photoshop CS5 and above.

    The H to S profiles are probably different from the native Hasselblad H profiles that Hasselblad supplied Adobe ... and most likely take into account the different specifications of the S sensor.

    What is missing from the Leica Owner's Area are the lens profiles for the Contax 645 lenses that was mentioned in the original sales update announcing the C to S Adapter.

    > "Use of corrective lens profiles for the Contax 645 system when converting the RAW files in Adobe Lightroom or Adobe Photoshop."

    Maybe those were supplied to Adobe directly, or use pre-existing profiles for C645 lenses ... but I've never noticed them in LR (???).

    Thanks for your help!

    A very long time will pass before I get a membership for a Leica Owner's Club I think.

    Leica R flange distance (FD) = 47mm
    Contax N FD = 48mm

    Re: Contax 645 Lenses on Leica S

    Thanks for the clarification on the profiles Marc.
    I would be very curious about profiles for the Contax lenses, especially the 140 and 210mm Sonnar lenses.

    I was referring to the lens correction module in Lightroom - it is a quick fix to create a development profile for each lens at a certain critical setting, if necessary, as long, as there are no profiles provided.

    Re: Contax 645 Lenses on Leica S

    Hello to all. I bought an adapter for C contax zeiss optics for leica s2, and I had same problem some of you. If the machine is turned off or goes into sleeping does not recognize the lens and does not work. You have to rotate (remove and replace) a little adapter ring and everything falls into place. Does anyone know how to fix it? Leica has managed to get on top of it? Thanks to all of you. The firmware of the machine is 1.3.0.0. and of the ring 135.5.0.0.

    Re: Contax 645 Lenses on Leica S

    I would love to see a comparison of a Contax 80F/2, Leica 70F/2.5, Hassy 100F2.2, and the Zeiss 110F/2 on an S2
    Anyone?

    Hi Hanny,

    I briefly had an adapter last summer, but unfortunately had the problems you mentioned. Besides, the fit was very tight and stiff. It wasn't easy to attach to the camera, so I got a refund and haven't really looked at this since then.

    I know of one high profile photographer who got the adapter a few months ago and uses it without any problem. So I guess it depends, some adapters seem to work OK, some not. I suppose if one is - with the help of a dealer - persistent to find one in good working order, it can be done.

    Succes and please keep us posted.

    Re: Contax 645 Lenses on Leica S

    I'd also like to know the state of the nation regarding the full fledged workings of the Leica S C adaptor, its existence now making the S2 one of my considerations since I have held onto a few bits of C645 glass...not bottom rung mfd, not top tier, but good enough IQ, easy useability, enough versatility for my needs and reportedly (since I haven't had the tactile experience) big, bright viewer.

    Would be reassuring if someone from the Leica camp could tell us that they have actually resolved these hiccoughs nine months on.

    Send me the Contax to S adapter and C80/2, Hassey V to S adapter and FE110/2 and I'll test them apples-to-apples against the S70/2.5 and Hasselblad HC100/2.2 with H to S adapter I already have.

    Can't promise with certainty that I'll return them

    Re: Contax 645 Lenses on Leica S

    Well, I have the V to S adapter, and I compared the 80mm Planar to the 70mm S (also the 30-90 zoom at 80mm), as well as the 110mm f/2 FE to the 120mm S. The S lenses were significantly better in all cases. They were so much better, in fact, that I somewhat regret purchasing the adapter, as I have wound up purchasing the S lenses in those focal lengths anyway...I bought it mainly to use for the longer end...180mm, 250mm FE and 350mm FE. What I found was that the 350mm is basically unusable on the S...vibration is rampant without mirror pre-release, even with a good tripod. It just gives me terrible results...it could be the lens, but it seemed just ok on film. The 250mm is better, and is ok stopped down, but it (along with all the Hasselblad lenses actually) have a fuzzyness to them that the S lenses don't. Part of this is the much higher contrast of the S lenses, but part of it is aberrations in the V lenses. Technology has come a long way since they were designed, and Leica set their mind towards building the best lenses, cost no object...they achieved it, but the cost is breathtaking!

    I thought I would use all my Hasselblad lenses and use the S lenses in my more common focal lengths, but once you use the S lenses, it is hard to accept anything else.

    I went through that comparison of V lenses on my H cameras Stuart. Since there wasn't anything to gain, and AF to lose, I moved on. However, having an adapter to put V lenses on the H camera helped make the transition easier over time

    Then I compared the Hasselblad stuff against the S system, and the S lenses punched beyond the size of the S sensor easily matching or exceeding the larger sensor H so I moved on. Again, the H to S adapter help make the transition less traumatic.

    I think there are a few reasons to use other make lenses on the S camera to fill in some focal length Leica doesn't make yet, or to provide some character for creative reasons.

    The only H lens I kept is the HC100/2.2. Having the H to S adapter for one lens is pretty pricy, but that's the one lens I wanted to keep for it's focal length, fast aperture, and resulting character that works so well for portraits. Plus it is AF and a CS lens for use with high sped sync to 1/750.

    What is amazing about the S lenses is how little effect the lens profile corrections have on most of them. In effect, less corrections means less destructive manipulation of the files.

    Now I'd like to add the new CS45mm, which I suspect would become my most used lens.

    Re: Contax 645 Lenses on Leica S

    Kim, maybe two years ago Mirex built a Contax 645 - Canon EF shift adapter (only mechanical, one has to close the aperture of the lens before by using a Contax 645 camera) for me, only recently Alpa borrowed me their Contax shift adapter for the FPS.
    Actually I had the Mirex already before I bought the FPS (used it on a 5DII), I took the Mirex to Alpa and tested the combo with the Contax 645 35f3.5 lens on the FPS before I purchased the camera. The good result might have encouraged Alpa to do their own (mechanical and electronical) shift mount:-)
