The 55mm Kolari Vision UV/IR Cut H-Alpha Lens Filter 55mmfrom Kolari Vision UV/IR Cut H-Alpha Lens Filter 55mmcuts 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. The filter has coated Schott B270 glass. This filter features an aluminum ring threaded on both sides.

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.

[Glass] Shoot aerochrome with you converted full spectrum digital camera. Works like a charm, just set your white balance and trees turn red but keeps the sky blue. No need to sit in front of your computer to swap channels. Ensure that your lenses do not create hotspots. Some lenses can create spots in the centre of images. 5

[Glass] This filter has greatly enhanced my photos of the night sky. I use a Canon EOS 6D Mark II that has a full spectrum modification and this filter helps reduce the red spectrum which makes the picture look more natural. 5

[IR/UV Control] I recently ordered this to have more options when shooting with a full-spectrum converted camera. It's great to be able to do false colour infrared without needing to use channel mixing in post production. It also opens up a wider range of treatments in the resulting files. I think it's my new favourite IR look. 5

[55 mm] I love this filter and it makes the quality of shoots much better. Highly recommended as long as you have a lens that fits the filter. 5

[Multi Coated] This is not a filter to have just for fun. First of all it requires you to have a Full spectrum conversion on your camera. Second of all it is for a very specific use and its price is no joke, so if you don't need it I would spend my money on something else I would use more. But in my case it's been a blast. I will use a lot more my converted camera now that I have it, and just getting started with experimenting out of the users manual I have a lot of ideas to work on with this filter. The filter only lets through UV light so exposure compensation is required and even under bright sun you will more than likely shoot on a tripod, with high ISO using slow shutter speeds. This filter is a tool, not a toy. 5

[Glass] If you use ND filters on BM pockets, you need this filter. period. Works beautifully and seamlessly. 5

[Glass] The BMPCC 4k's color is a little off because of IR, this fixes it to make it PERFECT. 5

[Aluminum] This cuts down IR pollution really well. It causes no color shift, especially when you're ND stacking on your lens. It's a tad bit pricey, but it's well worth the money. 5

[Glass] Efficiently blocks UVA and IR. No more reddish cast on black surfaces 5

[Multi Coated] I've been using the Kolari Vision IR Chrome Lens Filter on my IR full spectrum modified Sony a7iii with the 24mm G-Master lens. In order to achieve the vibrant red foliage colors with realistic blue skies and other colors, it is critical to have the correct custom white balance. At least with the Sony this required some experimentation as the usual gray card setting makes green foliage more orange than red (see photo), and this is very hard to correct in Lightroom. With my Sony, getting vibrant red foliage pushed the hues of other colors off a bit. Your experience may differ as I'm betting it's a function of the color algorithms in the specific camera being used. I did find that desaturating all color channels except blue can be any easy way to get b&w IR images with nice blue skies (see photo). Like all filters, plan to play with it a while to see how it affects your images under various circumstances. 5
