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

[Aluminum] 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 x 4.3 x 0.9"] Works as advertised. Will look to purchase an ND filter next..

[Dedicated] Best quality filters for my infrared photography!

[Dedicated] 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.

[Aluminum] I love the colors; the filter snaps into the Canon adapter and fits snugly. The Vari ND wheel spins somewhat freely, similar to the canon version. I wish it had some more tension on the wheel so it would feel more solid. But in no way effects the performance, it's superior to the canon in my opinion.

[Glass] 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.

[Multi Coated] Great to have a non-variable ND option for Canon drop in filter style.

[Multi Coated] 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.

[5 x 4.3 x 0.9"] Picked this up for use on my Canon R5C and I'm very impressed with the overall build quality. This is my first product by Kolari, but they have been on my radar for years with the Infrared conversions and magnetic filters they make. Happy to say this adapter and drop-in filters are very well built. The auto-focus features and communication with lens to camera has so far been perfect with my Sigma EF lenses, so I'm very pleased with that. The filters themselves are super clean and do not appear to have any color shifts or aberrations. And best of all, the control wheel for the VND is actually the right amount of resistance! Doesn't budge if you bump it (like the Canon brand one), but smoothly spins when you need to adjust it. At this price point, I'd recommend this kit over the Canon OEM alternative all day.
