The 86mm UV/IR Cut H-Alpha Pass Pro Lens Filter from Kolari Vision cuts UV and IR light when your camera's native UV/IR filter isn't strong enough and lets some IR light pass through. It can also be used in combination with ND filters that do not cut out IR light. And it also works as a protective filter, as it causes no color cast nor exposure correction. This pro version features multicoated Schott B270 glass in a slim, knurled brass ring threaded on both sides. (The optional standard version has an aluminum ring.)

Alternatively, this filter can be used with a full spectrum modified camera to provide more than four times the sensitivity in the H-alpha (Ha) line compared to most cameras' native sensitivity, and greater than six times the sensitivity in the sulfur II line. A full spectrum modification entails manually removing the camera's low-pass filter and replacing it with a clear filter. (Kolari Vision can make the modification for you at a cost if you send in your camera to them.) This Ha filter has a similar transmission to Kolari's hot mirror filter, but with an expanded spectral response covering the H-alpha and sulfur II emission lines, making it also useful for astrophotography.

Related Questions and Answers

Q: 1. Does this pass phantom power (48v)? The last xls barrel adapter I tried did not, making it useless form my application

A: Yes, the Shure A15HP does allow phantom power to pass through so it can be used with condenser microphones as well as dynamic microphones.

Q: 2. What about the A7siii or the Fx3?

A: Yes, the Kase IR 590 Infrared Filter for Sony Alpha Cameras will fit the Sony a7S III Mirrorless Camera and the Sony FX3 Full-Frame Cinema Camera.

Q: 3. I just received this lens and noticed a floating element that moves when I turn the lens end over end. Is this normal, like the focusing elements are free to move until the lens is mounted and camera is powered on?

A: While different manufacturers employ different mechanisms for various reasons within their lens (autofocus motors, image stabilization, etc), I believe in this case what you're seeing is part of their double-magnet linear motor AF system. It would most likely also be something that would only activate when the lens is powered.

Q: 4. Does the manual focus ring have a hard stop at infinity?

A: There are hard stops at both end of the focus ring while in manual focus mode. This is available with a push/pull action on the focus ring.

Q: 5. Does this XLR barrel adapter block Phantom power (48v)? I tried a different brand and it only worked on mics that did not need phantom power.

A: No, the Shure A15HP does not block phantom power and it does allow phantom power to pass through so it can be used with condenser microphones as well as dynamic microphones.
