[82 mm] Best high quality filter for my infrared photography. Very happy with it.

[Aluminum] 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.

[Aluminum] Best high quality filter for my infrared photography!

[Aluminum] Filter really makes a bold difference in astro imaging. Noting that the lens sun hood doesn't fit over the knurled edge of the filter. I can live with it since a sun hood is rarely needed at night... if I were to use this filter for artistic reasons during the day I might have another thought

[82 mm] Its almost magic. Se what your eyes can't see. Thats what this filter does in a full conversion camera, a tripod and a photographer capable of working with tools that are not for everyone. But if you pay what it costs and wait for it to be back ordered you are more than likely a committed photographer already. The filter can be used in a lot of scientific uses but I got it once I converted a full frame DSLR with still a lot of life ahead to full spectrum and got a very large set of filters to get the most of it shooting infrared and UV photography. So far it's been a great way to open new possibilities on creative photographic exploration.

[Aluminum] I’m new to IR photography. I’m using a Sony F828 with the magnet hack (Google it) & various external filters. I started with standard filters such as 720nm & 850nm but wanted something to pass more color for a more interesting twist. This 550nm delivers; it was worth the wait. It’s a lot of fun and making me enjoy photography again. There’s a lot of information out there about post-processing. Play with channel swapping (Photoshop channel mixer) to flex your creative muscles.

[Aluminum] After long ago exploring IR images with Kodak chemical films, I purchased the Kolari K665Pro and K720Pro to use on a stock Canon EOS 5D Mark IV and Canon lenses. I chose the Kolari Pro Gen series for their sharp cutoff spectra as well as their filter coatings compared to Kolari's base series or Hoya. The Kolari Pro quality / performance / price point trade-offs were great IMHO.

I posted a review of the 665 and can not say enough positives about it!!! 5 stars!!!

Still experimenting with the 720. It is slightly more technically challanging on a stock camera, but just as impressive as the 665 so far. Highly recommend the Kolari Pro Gen series for anyone getting into IR!!!

[Glass] Infrared takes a hole lot of experimenting. If you convert a camera I would say make a Full Spectrum Conversion. After that a full set of filters to se your options. This filter is one of the most user friendly filters you can get for it. Have fun with it if you get it.

[Aluminum] 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.

[Glass] 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.
