Building on the success of the well-regarded CP.2 lenses, ZEISS CP.3 28mm T2.1 Lens Sony E Mount Feetoffer the same full-frame sensor coverage and classic ZEISS look in an updated form factor and with improved mechanics and lens coatings. This 28mm Compact Prime lens is derived from the same classic optical formula as the preceding CP.2 variant and shares the same physical length as the 15, 18, 21, 25, 35, 50, and 85mm CP.3 lenses while maintaining identical focus and iris gear positioning with the entire set of CP.3 lenses, relative to the mount. All CP.3 lenses also share the same 95mm front diameter. Similar physical attributes across the lens line makes fitting lens accessories such as matte boxes, follow focuses, lens supports, and lens control motors easier and less time consuming.

Another feature handed down from the preceding CP.2 lenses is the interchangeable mounts. This lens comes with a Sony E mount installed. Though, if you wish to fit your CP.3 lens to a different camera, the lens mount can be swapped by the user for a separately available mount of a different kind. If you like the bokeh in your images to be round, even after stopping down, you will be pleased to know that the 14-bladed iris, made famous by the CP.2 lenses, has been retained.

Zeiss lenses are known for their clean and crisp image rendering. The CP.3 series of lenses is no different. This CP.3 lens will accurately color-match to other Zeiss cinema lenses inside and out of the CP.3 range. The CP.3 lenses feature improved lens coatings and anti-reflection masking over the CP.2 range for increased contrast and reduced flare, important for capturing content with the intent of an HDR-format release.

For enhanced ergonomics over the previous-generation CP.2 lenses, the CP.3 lens barrel has been reshaped to be more similar to the renowned Zeiss Ultra Prime lenses. This new shape is easier to handle, and takes up less physical space than the original Compact Prime design. An even weight distribution ensures that these lenses will be at home handheld, locked down on a tripod, or flown on a Steadicam or motorized gimbal.

Related Questions and Answers

Q: 1. will the autofocus on FX3 / a7s III / FX6 work with this lense ?

A: The ZEISS CP.3 lenses are manual focus only

Q: 2. Do CP.3's allow for a protective filter to be screwed on?

A: No, for any filters you will have to use a matte box.

Q: 3. How does this perform in terms of CA levels and purple fringing at all aperture settings?

A: It is our understanding that the optical properties of the CP.2 and CP.3 lenses are very similar. There were reports of some CA with the CP.2 lenses. Being that these are Zeiss, we doubt that this really is something that the cinematographer will be concerned about let alone his audience. CA is dependent on lighting, focus and aperture as well. We would encourage you to rent and test before you buy to make sure these lenses are for you.

Q: 4. Will this provide lens data such as iris t-stop/f-stop to any camera with an electronic EF mount?

A: The ZEISS CP.3 lens you are referencing has a PL mount and the meta data can be read by any PL type camera using the Cooke i/technology interface. The meta data is also accessible via the side port and can be read by such devices like the Ambient Master Lockit Plus. This would be the option when the CP.3 is fixed with an EF mount.

Q: 5. If I use this lens on a c300 Mark II there will be some crop correct? This lens is made for full frame camera?

A: The ZEISS CP.3 lenses - like the previous version CP.2 - are designed for full-frame cameras using 24x36mm sensor sizes. Since the camera in question uses an APS-C sensor of 13.8x24.6mm, it has an effective crop factor of 1.46x when using FF lenses.

Q: 6. With the Zeiss CP.2 Super Speeds being discontinued, does Zeiss intend on releasing a CP.3 Super Speed line to take their place?

A: there has been no official statement from Zeiss about a Cp.3 line of super speeds

Q: 7. Will this work with the FX3?

A: Yes, the ZEISS CP.3 35mm T2.1 Compact Prime Lens (Sony E Mount, Feet) is compatible with the Sony FX3.

Q: 8. can fixed uv filter?

A: It is not possible to fit a UV filter to the ZEISS Compact Prime CP.3 lenses. Like most cine lenses, they are designed for use with a matte box and cut filters.

Q: 9. Does this lens send metadata to bmpcc 4k?

A: The ZEISS CP.3 XD lenses transfer meta data using the Cooke /i Technology protocol. This is available only on select cameras using a PL mount. The BMPCC with MFT mount does not support the /i Technology protocol and neither does the standard ZEISS CP.3 EF mount lens. You could use the BM Ursa Mini Pro with PL mount along with the ZEISS CP.3 XD PL and then there would be a meta data exchange.

Q: 10. do these have a front thread?

A: Zeiss CP.3 Lenses do not have a front thread.
