37mm 850nm IR pass filter test

I agree thermaldog!

looks good but would be nice to see a standard visual video to compare the two.

I hope you will believe me but you did catch a few in your shot of the trees (frames33,34, 35) there are alot of ufos that are small look for orbs that reflect light on all sides, also when they move they will leave behind a black smoke trail and or burst of white vapors. move your camera slower they like the trees to hide in during the day

for some reason they show up on google earth

@tlo0942 UFOs? Ok, perhaps you need to make a video about the UFOs in my video... I don't see anything out of the ordinary...

hi!! im going crazy over the set up for my IR850, and we have the same brand LVSHI from china, but when i set it up on my lens i see nothing? what do i need to do? thanks!

[jjuup]

@chrissydelvalle Did you turn on night vision?

[AreaQNH870]

In the time it takes for you to make this clip, my camera's shutter is still open, begging for more light! 850nm may have been a bit too deep for the old girl!

[jjuup]

@AreaQNH870 You must enable "night shot" mode. You did that, right? !)

[LikeAVideo]

Does a normal camcorder with no nightvision do this with a IR filter threaded in front of the lens?

[jjuup]

@LikeAVideo Not by default. It might be possible to remove a built-in IR cut filter from the "normal" camera by opening it up thou...

[kaidzzUUUU]

Must try - 850nm + circular polarizer filter!

[jjuup]

Good idea!

[WilliamRayWalters]

What brand filter is that, where did you buy it, and how much did it cost you? I'm just curious. I've tried different brands with different results.

[jjuup]

The box says "LVSHI Acessory"? I bought it from ebay from China for 12.95usd including shipping.

What brands and nanometer values have you tried? I think I have to save this 850nm for cloudy days and get a 1000nm for sunny days. This one lets too much UV pass and the image will burn.

[jjuup]

Seems the 850nm will burn trough quite easily.. the sun just came out and I did a new test, but it's all white... I think this lens will work on dark/cloudy days and I need a new one for sunny weather.

Any other users that can comment on this?

@jjuup IR pass filters act as an exposure control when in nightshot because the camera's aperture is opened to the max to prevent the x-ray effect during the day. So if your image is still to bright with a 850nm, just increase the amount of IR light being blocked and try a 920nm or 1000nm filter.
