[Glass] This thing is a lot of fun! The prices are lower than they were years ago, the image results with a sony a6500 are great!

[Glass] I am using this filter with a Nikon D100 (unmodified) equipped with a Tamron SP AF Aspherical XR Di LD IF 28-75mm 1:2.8 MACRO lens with excellent results.

[67 mm] I've only played with it a couple times but a fun gadget for a hobby photographer

[0.13 lb] This filter works as advertised and gives great results. When used with a Nikon D70 in camera metering works perfectly and different results can be achieved by just changing the aperture. Frame the shot, focus, and then place the filter on the lens. A tripod is a must.

[67 mm] I tried this on my Nikon D7100. First of all, it's so dark you can't see anything with it on the lens. Even live view doesn't show anything. So you focus and compose before putting it on(or just guess at focus and composition). I shot at ISO 6400 and several seconds of exposure were required on an overcast day at f/5.6. In color the images were almost all red. Converting it to B&W gave the effect of B&W IR film. But it seems like the effect was stronger back when I was shooting the IR film.

[Glass] Works very well with my Mamiya 645 lenses and Fuji X-T2 body converted to full spectrum. I'm in love with infrared photography, a different way of looking at the world...

[67 mm] This is a fun way to add some colorful creative effects to your instant photography. The look can range from subtle to very pronounced depending on your subject and which filter you use from this pack. I say if you like the samples shown on the product package, you'll probably have a lot of fun with this. Included are two photos I made, one with the Austin filter and one with the Northern Lights filter.

[Glass] Very happy with this filter. Takes some post-processing to bring out the images, that is the most challenging part for me but getting better with practice. I use it on a 12mm Rokinon Micro 4/3 lens mounted to an Olympus OM-D E-M10. I find the manual aperture and focus make it much easier to use with the infrared filter than an automatic lens. It also works on the 40-150mm telephoto lens with a 58mm-67mm filter adapter, but with this lens you first need to remove the IR filter, compose the image, attach the filter, increase the exposure time appropriately then take the shot. Even with a stable tripod it can be tricky to do all that without moving the lens somewhat. I use Lightroom and Photoshop to adjust the white balance and reverse the blue/red channels to bring out the dreamy light tones that come out so nicely in infrared photography. Most shots seem to come out best in black and white but a few have come out nicely with some low saturation color. Highly recommend this filter for anyone wanting to try experiment and try something different!

[67 mm] I love it! It's just what I needed for that extra jazz in my photo's.

[0.13 lb] I thought it would be interesting to merge the uniqueness of a Lensbaby Velvet 85 with an IR filter. Both IR photography and shooting with the Velvet lens are new for me and I am loving the experience of learning and creating.
