Compatible with 4K cameras that have a 1/1.8" sensor, the EG3Z0409KCS-MPWIR CS-Mount 4-10mm P-Iris Lens from computar has a 147.8 to 53.3° diagonal field of view. The lens's IR-corrected optics enable a camera's sensor to take in visible and IR illumination in low light conditions (when the IR cut filter is in the open position), while eliminating the problem of IR focus shift. Featuring P-iris control, the lens automatically adjusts iris position to optimize image quality in varying lighting conditions while improving clarity and depth of field. Focus and zoom are manual.

Related Questions and Answers

Q: 1. Does this lens makes hotspots on infrared converted cameras?

A: The Rokinon 10mm f/2.8 ED AS NCS CS Lens for Nikon F Mount is a pretty standard wide lens. It should be fine for using it on an IR converted camera. It is not a high level lens. So there are sharper lenses but it is fine.

Q: 2. Folks, this lens looks fantastic, I only want to know one thing: is the Aperture ring de-clicked? I am looking to use this to shoot video, though I'd rather not pay an extra 60$ for focus/iris gear rings - If this lens' aperture is de-clicked that would be perfect for me and I'd love to know.Thanks in advance, you beautiful people

A: Christopher,Unfortunately this lens definitely has a click on the aperture ring. The click is not super heavy, but is most certainly there. It's a great lens! But if this feature is something you're trying to stray away from, then I wouldn't recommend this particular lens to you.

Q: 3. Would this work on a Canon EOS500D? If so, what would I need to do in-camera to make it work?

A: Yes this lens will be fully compatible with your camera and won't require anything else. Just keep in mind that it will be manual focus only.

Q: 4. Does it pass the fstop data so that it can be recorded with the rest of the meta data for the picture?

A: No f-stop data is not recorded.to the meta data of the camera , the camera will think you are photographing without a lens

Q: 5. Can this be used in manual focus mode on the a6000?

A: All Rokinon lenses are fully maunal focus lenses. As such, while the Rokinon 10mm f/2.8 ED AS NCS CS Lens for Sony E Mount would attach directly onto the Sony Alpha a6000 Mirrorless Digital Camera, you would have to focus the lens manually on the camera.

Q: 6. Does this really weigh 1.38 lbs? That's almost double the Fujifilm 10-24's 14 oz.

A: According to the box 22oz. Not that bad really. I have used it on my A6000 while hiking. Upgrade to a aftermarket strap, or use it on a tripod. Manual focus and aperture, but a third the cost of the Fuji.

Q: 7. Is this lens good for astrophotography? More specifically, coma and chromatic aberrations of bright stars not in the center of the image.

A: This lens would be suitable for your application.

Q: 8. what about square filters? (cokin etc)

A: Unfortunately, it does not appear as though a filter holder is available for this lens at this time.

Q: 9. Can this be used on Canon EFmount to MFT Metabones Speed Booster?

A: This lens has the EF-M mount for the Canon mirrorless lenses, which is different than the EF/EF-S mount. It would not be compatible with an EF to MFT mount adapter, nor is there an adapter to mount an EF-M lens on a Micro Four Thirds camera.

Q: 10. Hey Folks, can i use this lens on my full frame Canon EOS 6D without getting any vignetting on the corners?

A: It says designed for APS-C sized sensors which means it is built for APS C sensors which means: Yes, you will have black corners with a full frame camera. And it's not vignetting - it's real black corners.
