If you want to swap out the mount on your CP.3 lens, this ZEISS Interchangeable Lens Mount will allow you to convert your lens to ARRI PL with Cooke /i mount. All materials necessary to swap the mount are included, as is a lens cap to protect your lens after the new mount is installed. While the process of swapping the mount is relatively simple, B&H recommends that for ideal performance and accurate collimation, the mount-swap process be carried out by a certified lens technician.

Note: This mount will only enable the transmission of lens metadata with XD enabled CP.3 lenses

Q: 1. Given that light transmission ramps, as others have discussed, if my light meter suggests exposure at f/5.6, for example, will I have to make adjustments to the aperture, depending upon the focal length I am using for a shot?

A: You will not need to make adjustments to the aperture, depending upon the focal length. You will want to make adjustments to the aperture depending on your meter's exposure reading.

Q: 2. Does this lens have filter threads, and if so, what is the diameter?

A: This lens does not have a filter thread. However it does have a 114mm front lens diameter, which is common for use with matte boxes.

Q: 3. will this work with the original alexa mini?

Q: 4. What thread size is the lens support? Do you have any recommendations adapting this to 15mm rods?

A: The thread present on the bottom of the ZEISS 21-100mm T2.9-3.9 Lightweight Zoom LWZ.3 Lens (E-Mount, Feet) BH #ZE21100EF is 3/8"-16. There are various 15mm lens supports to consider depending on budget, but a great option is the Bright Tangerine Morrissey 15mm LWS Lens Support with 3/8" Post BH #BRM15LS38P • MFR #B3010.0002. https://bhpho.to/2V1V2ZX

Q: 5. Hello. I have a Sony FS5 and a APS-C sized Canon DSLR and want to be able to use this lens for both cameras. I have an EF to E-mount Speedbooster adapter to use EF glass with the FS5. If I attach the EF version of this glass using the speesbooster will I get vignetting at wide focal lengths?

A: This lens covers an APS-S or Super 35mm Sensor. If you used it with a Speedbooster, you will see some vignetting. You really would want to use this lens with a standard adapter. Zeiss also happens to offer an Interchangeable Mount Set for this lens, B&H # ZE21100IMSE. You would be able to change it between a EF and E-Mount with this kit.https://bhpho.to/2AcTQDV

Q: 8. Can lwz.3 cover whole red weapon's 8k sensor?

A: The ZEISS LWZ.3 does a good job of covering the RED Helium 8K Super35 sensor. If you record in either 8K WS (1.85:1) or 8K HD (1.78:1) mode in the camera, then the 21-100 image circle is large enough to project a complete image, with slight darkening of the edges when in the widest zoom setting. When in the 8K FF (Full Frame) setting, you will see vignetting around the top and bottom of the frame. If you go past 23mm to 25mm, the image becomes quite clean from edge to edge.

Q: 9. When this going to come for Sony E mount ?

A: Unfortunately the manufacturer has not yet announced plans for any additional mounting options. However you could use a pl to e mount adapter to appropriately mount this lens to an e mount body. We suggest the Metabones MB_PL-E-BT1 https://www.bhphotovideo.com/c/product/1194555-REG/metabones_mb_pl_e_bt1_pl_to_e_mount_adapter.html

Q: 10. In EF mount, will this lens work with an EF to MFT Metabones .71 Speedbooster?
