Zeiss Cp.3 28mm T2.1 Compact Prime Lens (nikon F Mount, Feet)
- Product Code: ga42551
-
Building on the success of the well-regarded CP.2 lenses, ZEISS's CP.3 Compact Prime Lenses offer 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 features an all-new optical design over the 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 Nikon F 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.
Note: While the CP.3 lenses are designed for a degree of user-serviceability regarding the mount, for ideal performance and calibration, B&H recommends that mount swaps and other lens adjustments be done by a trained lens technician at a service center.

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.

Q: 3. Have they fixed their aperture communication problem with Sony? Loxia lenses have issues with bodies newer than A7iii
A: The Zeiss Nano Primes do not share components with Loxia, and are fully compatible with all Sony E-mount cameras. Zeiss has tested them extensively on everything from an A7IV to the Burano & Venice and they have discovered no compatibility issues.
Q: 4. Can the Xenon handle S35 Sensors at 8k?
A: Yes

Q: 7. Sirs, will this cover the newest (RED) Dragon 8K sensor? Or will there be vignetting? Thank you in advance.
A: The RED Dragon 8K sensor has an image diameter of 46.1mm. The Schneider Xenon FF 25mm T2.1 Lens is designed to cover a Full Frame image diameter of 43.4mm. There will be vignetting.
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. Can the Xenon handle S35 sensors at 8k?
A: Yes... I have a Red Epic-W with 8K Helium SensorPerfect picture
Q: 10. How are these compared to the Rokinon Xeen?
A: Cine lenses such as the Schneider Xenon and Rokinon Xeen share the attributes that are so needed in prime lens sets for movie production. Principally these are consistent physical size and consistent image quality. Inconsistent size slows down production and inconsistent image quality slows down post-production with a possible affect of the viewing experience. What differentiates the two brands essentially is that the Xeens are good quality while the Xenons are even better. If the budget is limited, go with the Xeens confident that you will get good results. If the budget is more generous, go with the Xenons. What you will get is superb design, build and image quality that you can feel and see. The Xenons will last for years in hard, 18 hour a day movie production.
