[0.275 lb] 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.

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

[Brass] OK if you are not sure if you will use it don't buy it. But if you have a full spectrum camera, this is one of your filters in your IR, UV filter set. Color IR is not for every one but it can be a blast if you find a way to understand what this filter can do for you.

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

[39 mm] 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.

[Glass] 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.

[39 mm] 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.

[Brass] I have only tested this filter on my Lifepixel-modified Canon R6 (v1), but I like it already. It produces some really interesting color combinations that my other Lifepixel IR filters do not. Samples below are with custom white balance in-camera.

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

[39 mm] 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.
