The 100 x 100mm Kolari Vision Blue IR/NDVI Pro Filter 100x100mmfrom Kolari Vision Blue IR/NDVI Pro Filter 100x100mmis designed to fit Lee or Cokin Z-Pro square filter holders. This filter works with full spectrum cameras to transmit both blue and IR, making it ideal for NDVI crop analysis applications. It allows an NDVI to be generated from a single image using the blue and red channels of the image. This filter is also useful for landscape photography, as it produces a similar effect to a 590nm IR filter after a channel swap, right out of the camera.

A full spectrum modification is required to be made to your camera. This entails manually removing the camera's low-pass filter and replacing it with a clear filter. Once that's done, this filter will work as intended. (Kolari Vision can make the modification for you at a cost if you send in your camera to them.)

Q: 1. Is this Kolari filter actually compatible with the Canon brand ef-rf drop-in filter adapter?

A: Yes the The Kolari Vision VND Drop-In Filter is a 2 to 10-stop variable ND filter compatible with the EF to EOS R drop-in filter adapter from Kolari or Canon. So it can fit either brand of the drop in adapter.

Q: 2. How much light do I lose using this filter? Will I be able to hand hold the camera at ISO 200 and f2.8?

A: Using the Kolari Vision Pro Gen 3 Infrared Lens Filter (780nm, 77mm) on a camera not converted to IR the filter will block 10-15 stops. Using it with an IR converted camera it will be about 1-2 stops of light.

Q: 3. Is this the Pro 2 version? The picture shows Pro 2, but the description doesn't. THanks

A: Yes. The Kolari Vision UV/IR Cut Hot Mirror Magnetic Clip-in Filter for Sony E-Mount Full-Frame Cameras is the newer Pro 2 version.

Q: 4. Does this filter have to be used with a full spectrum camera?

A: While it may be possible to use the Kolari Vision Pro Gen 3 Infrared Lens Filter (930nm) on an unconverted camera using a long exposure, it is not advised. One would not get good results on a normal camera. The only options for infrared photography when using a normal camera are the 720nm and 850nm filters.

Q: 5. Will this filter help astrophotography in an unmodified Z9?

A: If the Nikon Z9 is not modified it won't help much for astrophotography. I wouldn't recommend it.

Q: 6. Is there a difference between using this vs the IRND version (#KORDINIRND6P), specifically for video capture?

A: The BH #KORDINIRND6P is only 6 stops. You cannot change the number of stops that it reduces. It is not a variable ND. The Kolari Vision VND Drop-In Filter for Kolari/Canon EF-EOS R Drop-In Adapter BH #KORDINVND210 is a variable ND filter. You can change the stops that it reduces between 2, 3, 4, 5, 6, 7, 8, 9, and 10 stops.

A: The Kolari Vision RF to EF Drop-In Filter Adapter with VND, CPL & Clear Drop-In Filters does support camera to lens communication including autofocus.

Q: 10. Does this have all included for florescence photography with a regular camera? or is a filter needed for camera front?

A: The The Kolari Vision KV-FL1 Multispectral Flash with IR and UV Flash Filters is made to work with a full-spectrum modified camera. But one can use it without. Results will vary.
