[0.14 lb] Best high quality filter for my infrared photography. Very happy with it.

[0.14 lb] This filter is easy to put in and easy to remove. The mounting mechanism works really well and the all metal construction is very durable. The filter itself is high quality and works very well. Kolari customer service is also fantastic.

[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 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. Starting with the 665, I set the camera for manual exposure (typically bracketing around +2) and manual focus (typically longer focus settings), and the stock sensors pick up enough red for good composition and control. It has been a short learning curve and I am most pleased with the images that the Kolari filters are generating: awesome black and white landscapes, cloudscapes, and waterscapes, and excellent starting points for post-processed color shots (native red hue or channel swapped)! No discernible color aberration until I push the image magnification to its pixel limits. The coatings have been great with tough lighting angles - no flares - and stay remarkably clean in windy, dusty environments! Continuing experiments with the 720, which pushes the limits of the stock sensors but still works well. Highly recommend the Kolari 665Pro for anyone getting into IR!!!

[67 mm] 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.

[0.14 lb] Best high quality filter for my infrared photography!

[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.

[0.14 lb] 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.

[67 mm] Works great on full spectrum cameras. Lets you get into the deep infrared on 720nm or higher converted cameras.

[0.14 lb] 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] 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!!!
