Related Questions and Answers

Q: 1. 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: 2. Does it have a 1/4 -20 thread on the bottom for a lens support?

A: The ZEISS Light Weight Zoom features a 3/8 support collar for lens support.

Q: 3. Is this lens par-focal?

A: You probably need shims to custom adjust this depending on what camera you are using. Factory lens put on a camera is completely NOT parafocal for me.

Q: 4. 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: 5. Are there any extenders (doublers) that will work for the LWZ.3 with an EF-mount? (the Canon EF 2X III will not work)

A: ZEISS does not offer an extender for the Lightweight Zoom LWZ.3 and does not recommend a 3rd party product due to the changes in the optical performance of the lens.

Q: 6. Is there a servo available with this Zeiss lens?

A: A servo controller is not available for the ZEISS Lightweight Zoom LWZ.3.

Q: 7. Can this be used on a C70 with the Canon Mount Adapter EF-EOS R 0.71x?

A: Yes, the ZEISS 21-100mm T2.9-3.9 Lightweight Zoom LWZ.3 Lens (EF-Mount, Feet) can be used with the Canon Mount Adapter EF-EOS R 0.71x, but only in S16 mode, to achieve a super 35 image circle.

Q: 8. Has anyone tried using an extender / doubler with this lens (EF-mount)? The Canon EF 2X III does not work (physical restraints).

A: We are not aware of a 2x Extender that is compatible with this lens.

Q: 9. Does this lens works great with Canin C500 PL?

A: If you have to ask this question you don't need this lens.

Q: 10. At what T stop does the lens start to go down in exposure?

A: On the ZEISS LWZ.3 zoom lens, the aperture ramping is linear from 21mm - 100mm, meaning as you rack the zoom at wide open aperture, the light transmission changes from T2.9 - T3.9 in continuous, even steps.
