Related Questions and Answers

Q: 1. This focal length is very prone to sagittal coma flare. Does the Otus 28mm resist this? Especially with off axis bright lights?

A: At worst, the flares will look artistic and beautiful ... everything is beautiful through that lens (not kidding !). But yes, stopping the lens down even to 1.8 will likely eliminate it.

Q: 2. Does it have weather sealing gasket?

A: Yes it does according to the information provided by Zeiss.

Q: 3. if i were to use the manual focus Zeiss Milvus on a 5D Mark iv, are there replacement focussing screens for the camera?

A: Unfortunately 5d mark iv focusing screen is not user replaceable and we do not carry any options for that camera.

Q: 4. Which of the two filters is the best? Heliopan or Zeiss polarizer? For this lens.Thank you.

A: I don't have much experience with Heliopan, but I have several Zeiss polarizers for various lens. I have the Zeiss polarizer for this lens and it is amazing. However, I think it depends on what type of photos you want to take and location.

Q: 5. I see aperture ring and numbers in the product image. If this was used on D7200, does the camera recognize the aperture selected on the ring? And how do the 1/3 aperture stops work?

A: The aperture selection on the ZEISS Milvus ZF.2 lenses can be done using the ring on the lens barrel, or via the sub-command dial on the camera. This choice needs to be made in the set-up menu on the camera (refer to the D7200 user manual for more information). When the aperture ring on the lens is chosen, the aperture is changed in 1/2 stop increments. When the aperture is controlled via the camera using the sub-command dial, then the aperture can be controlled in 1/3 stop increments. When using this method, the aperture on the lens should be set to the lowest level until it clicks into place. Otherwise you will see EE readings in the camera menu.

Q: 6. Is anyone using this lens on a Nikon D800? If so, how easy or hard are you finding it to nail focus where the subject is not perfectly still?

A: It takes some practice. I did a shoot recently with the milvus and I missed a lot of shots. I made it a point to keep the lens on my camera most of the time. I find using the guage in the view finder helps a lot.

Q: 7. is the manual focus linear or fly by wire?

A: The ZEISS MIlvus lenses are true manual focus and do not rely on electronics or motors to focus the lens groups.

Q: 8. Do I have the adjust the aperture using the aperture ring or can I adjust it using the controls on my camera?

A: Both options are available. The lens is fully compatible using your cameras auto functions. But can be used with manual aperture control for video applications by declicking the aperture ring with the provided key.

Q: 9. Can this lens be used on a Nikon Z7II with the FTZ Adapter?

A: The ZEISS Milvus 21mm f/2.8 ZF.2 Lens for Nikon F is compatible with the Z7 II when used with the FTZ adapter.

Q: 10. Canon focus screens

A: There are no interchangeable focus screens for the 5dmkiii. There is a focus confirmation beep with the center af point. If you have a eos1-n, 1-v, eos 3, or even a 5d up to mkii, they all accept the same screens. There is a split image/ microprism Fresnel (Ec-B) that would be helpful for those cameras; it is sold by B&H, but it is on backorder now. With 5dmkii just use af confirmation, or shoot in Live View and magnify to confirm focus. The microprism fresnel's are all in the Center anyway so it's the same deal. Wide open handheld with a figity subject is a tough. This lens is a powerful tool, but it does take a certain dedication to work with it. The results are worth the effort. Good luck!
