Zeiss K Mount Lenses

ZF.2 lenses support all key modes (e.g. aperture priority, shutter priority, program AE or manual exposure settings) on camera models equipped with an electronic interface (e.g. current Nikon DSLR cameras). To do so, simply lock the aperture ring in the largest f-stop (e.g. 16) shown in orange. On camera models without an electronic interface, the aperture is manually set on the lens aperture ring. With some camera models, it is possible to set in the menu whether the lens should be selected using the setting dial on the camera or the aperture ring on the lens. Please note that, for technical reasons, there is no halfway notch between the largest (e.g. 16) and second largest (e.g. 11) f-stop. The focused distance is not transmitted to the camera body.
The manually focusable ZE lenses (for EF mount) feature electronic shutter control and additional electronic contacts to the camera. All existing exposure programs (P, AV, TV, M) and the AF confirmation function of the camera are supported; lens information (focal length and speed) is passed on to the camera. Certain functions that require the use of AF lenses (various scene modes, A-DEP) are partially unavailable.
ZE lenses are compatible with the EOS camera bodies listed here, and further cameras with EF mount (e.g. cameras for cinematography). When using adapters with electronic contacts on cameras with a different mount (e.g. mirrorless system cameras, cine cameras), we cannot guarantee for the compatibility and functionality of ZE lenses. Therefore, the compatibility specifications of the adapter and the camera manufacturers have to be followed. Using ZE lenses with an adapter is at your own risk. Defects on the lens, the camera or the adapter caused by the use of an inappropriate adapter or by improper use will not be covered by our manufacturers warranty.
The manually focusable ZS lenses (for M-42 screw thread) are equipped with a push pin in order to close the aperture. Furthermore, they are equipped with a locking switch to change from manual to automatic aperture control. Due to this, the lens can be comfortably stopped down to working aperture when used with an adapter. The aperture priority can be used as well.
The manually focusable ZF lenses (for F mount) are equipped with the AI aperture coupling as well as the pre AI coupling. They do not include CPU coupling. Due to this, exposure metering and control is possible with all corresponding camera models. Used with camera models without AI or fork coupling the aperture is closed to the pre-selected value, but metering and automatic aperture control is not possible.
manual correction not possible
is possible to a limited extent if the camera model allows aperture priority setting
additional functions available by entering the speed and focal length in the camera menu
When I mount the Voigtlanders I am presented with a menu to select the focal length of the lens. I read in the manual that selection does affect IBIS. I have also verified that it comes through in the exif data.
I have taken thousands of photos with it across multiple continents. It has been rock solid. Image quality is outstanding. Candidly, I zoom by crop because of the resolving power of that lens with a 60mp sensor.
The only benefit of using the M-L adapter from Leica is that the 6Bit coding from the lens tells the camera the correct lens and adds in-camera lens correction. It only applies to Leica lenses with 6bit. Vintage lenses or other brands only give you IBIS and no corrections.
And only with the adapter the EXIF info is saved properly. With third party adapters you can chose a lens profile manually, but the EXIF info will stay empty. I think the lens profile is used properly in camera. I bought the M-L adapter just for the EXIF info when I choose a lens profile for my mostly uncoded M lenses.
Mind you that when you stack a R-M adapter it needs to be coded, otherwise the SL will only present M-Lens profiles to choose from. It sees an uncoded R-M adapter as just an other unknown M lens.
Anamorphic lenses have different effective focal lengths in the vertical and horizontal directions, so I'm not sure that's even possible. In addition, "non-perfect" anamorphics vary across the field. I'm not sure that anyone has ever made a "perfect" anamorphic. I'm not even sure that anyone would want one, since it would look like a regular lens.
They just used the nominal focal length, which you can also do on any SL with IBIS. My concern is that anamorphic ratios aren't really constant throughout the frame, so you'll end-up with parts of the image that are under-corrected or over-corrected. This could lead to strange IBIS artifacts.
For instance a 50mm 1.5x anamorphic has a field of view similar to a 33.33 mm lens horizontally (50/1.5). In theory that's fine, your IBIS corrects for 50mm, and that correction is "stretched-out" when you view the image at a 1.5x ratio. However, "1.5x" is really just an average. It could be 1.4x in the centre, and 1.6x at the edge of the frame. There are some historical prism anamorphics that have a constant stretch, but you are unlikely to be using those on a hybrid camera.
It's strange that it works without any special modes in CineD's footage, but not on Leica. CineD used a Fuji body, but that shouldn't make a difference. Have you posted your footage, I'd like to see how it affected the footage, for instance if the movement is just horizontal, just vertical, or both.
I purchased a 25mm Zeiss c-mount lens off of Ebay. As it turned out it is a macro lens, but what a lens it is! It's really sharp and crisp. The color almost seems more saturated! Anyway I'm trying to find more c-mount Zeiss lenses for my Bolex. Does anyone know where to look? I can't find anything on Ebay right now. I got this on from Slovakia for $50. Any ideas?
I understand for the most part why I shouldn't use any lens but an RX but I have recently shot footage with this lens and the footage looks quite nice and sharp but with a very narrow depth of field. I originally thought the lens was a standard 25mm lens but I can only focus the lens a few inches from the camera so I thought it might be a macro lens. Could this macro effect be caused by the fact that it isn't an RX lens?
Please respond to those whose RF series camera does not detect the Zeiss ZE lens? I have two cameras. One is a Canon EOS 6D and the other is an EOS R8. The EOS 6D camera is equipped with a Carl Zeiss 50 1.4 ZE lens. But the R8 camera does not see the lens. There is a dash in EXIF.
I use the original Canon EF-R adapter. Zeiss lenses have electronic contacts. Canon R8 controls the lens aperture and allows the use of focus assistant. But the R8 camera does not write the name of the lens in Exif. The Canon 6D camera writes the name of the lens into the exif. I want RF system cameras to register the name of the Zeiss lens in Exif
Unfortunately, like most camera makers, Canon do not take responsibility for 3rd party equipment that people attach to their own equipment. This is not unique to Canon, the same thing applies to all major vendors.
That fact that Canon cameras worked with Zeiss lenses is more a function of the fact that Zeiss themselves did the work to make that happen. The onus is always on the 3rd party, not the OEM. The fact that Canon have changed their platform may cause those compatibility efforts by Zeiss to be compromised, I would certainly not expect that Canon will take any action on this from their end.
As Rick suggested, you might try some measures to turn of features specific to the RF mount lenses. Also, what brand adapter are you using from the lens to the body?
I only use original Canon adapter. I think Canon will not agree to the meeting and the lenses will never be registered in Exif. I wonder if the Voigtlander Nokton RF 50 1 brand will be registered in the Exif file? Zeiss and Voigtlander lenses are manufactured in the same factory. And even their design is similar
The way that the design system with cameras works is this: A camera maker designs a lens mount as part of designing a new camera platform. It then designs various bodies and lenses for that new mount and those bodies, and releases its own lenses that it will support, and are rigorously tested to work with said mount. It makes no warranty or implication that lenses from third parties will work with its new platform as they have not been involved in the process.
A third-party company either has lenses for an earlier mount, or wishes to build new lenses for the new system. It will engage with the camera OEM for access to the certain information that may include firmware code, and will likely (especially these days) be covered by a licensing agreement between the OEM and lens maker. The third-party lens maker will likely test their current lenses to see how they perform and, based on those results, may issue firmware updates to bring their existing lenses up to spec to work with the new mount. This is exactly what Sigma did with their lenses and released a video to that point.
