Q: 2. can you use this lens for video?

A: I would think that the IRIX 15mm would be ideally suited to video, especially in industrial situations where one is often restricted in getting a wide field cover shot. This lens could turn a broom closet into a large room.

Q: 3. Will this lens work on a Nikon D3300?

A: Yes, the IRIX 15mm f/2.4 Firefly Lens for Nikon F is compatible with the Nikon D3300.

Q: 4. Do this lens have Sony e mount?

A: Unfortunately for the time being there isn't one.

Q: 5. Does Pentax K version has aperture confirmation chip?

A: I'm pretty sure this lens is fully manual. However being so wide.. it's not hard to use at all. It has a stop to keep it in focus. It's an amazing lens and one of my favorite from my 10 plus collection.

Q: 6. can this be adapted to a sony mirrorless with a dumb adapter? will this work with an adapter that has aperture control ring?

A: I adapted it to my Sony A7RII with no issues. Loving the performance. I used smart adapter though as the aperture is controlled automatically through electronic control. You can buy one of the cheap ones that cost around $50. I used the Canon EF version.

Q: 7. For the Pentax mount version, will it work with a film Pentax camera like the ZX-5n which has Av and Tv settings or the fully manual K1000 SE? I understand that there is no aperture ring so I would not be able to select the aperture on a fully manual camera like the K1000 and the aperture would default to 22 which would be fine for my intended purpose (landscape photography with a large DoF mounted on a tripod). Was wanting this to use with a K-1 Mk II special for night sky astrophotography landscapes and also be able to use it with my old ZX-5n and a K1000 SE for daytime landscapes. I already have a 95mm night sky light pollution filter - which is why I would prefer this lens over the Roki 14mm 2.8 which won’t accept filters but does have an aperture ring and would likely work fine on my film camera.

A: It will mount to the older Pentax film cameras.

Q: 8. ¿Funcionará esta lente con la Canon EOS 800D?

Q: 9. What is the difference between the Firefly model and the Blackstone Model? Which would be better with a Canon M-50 with the M to EF/EFS adapter? Can it also be used for landscape photography? Thank you for your time

Q: 10. Does this lens work on Nikon Z6?

A: I contacted IRIX with your inquiry. They replied that the compatibility of IRIX lenses with Nikon Z cameras (with FZ adapter) has been announced on their Instagram account on October 2018. They state that there are no issues with using IRIX lenses with the Nikon Z cameras using the FTZ lens mount adapter, so you should have no issues using the IRIX 15mm f/2.4 Firefly Lens for Nikon F on the Nikon Z-series Mirrorless Digital Cameras with the FTZ Lens Mount Adapter. The lens' focal length and aperture information will also be transmitted to the camera's EXIF data, along with exposure settings. That being said, do note that this is a manual focus lens, so you will still have to focus the lens manually when using the Nikon FTZ Lens Adapter.
