The 39mm, 850nm Kolari Vision Infrared Lens Filter 39mm 850nmfrom Kolari Vision Infrared Lens Filter 39mm 850nmblocks visible light up to 850nm from the light spectrum. It features uncoated glass in an aluminum ring with 39mm threading on both sides.

Unlike the 550/590/665nm versions of this Kolari filter, this 850nm version does not require a full spectrum modification to be made to your camera, but only as long as you use the camera mounted on a tripod and set it to shoot long exposures. Otherwise, a full spectrum modification is required. That entails removing the camera's low-pass filter and replacing it with a clear filter. Once that's done, this 850nm filter will work as intended. (Kolari Vision can make the modification for you at a cost if you send in your camera to them.)

Blocks Visible Light up to 850nm Requires Tripod or Modified Camera Glass Filter / Aluminum Ring Dual-Side Threading

Q: 1. Does this remote work with the Pentax K20D?

Q: 2. Is this IR Filter lens?

A: No, it's the opposite -- it lets IR light through rather than filtering it off.

Q: 3. Does this fit Leica E39 lens?

A: Yes this will fit on a Leica E39 Lens.

Q: 4. what mount adapter would i need to use this on a gh4?

A: C-Mount to MFTYou can get it on ebay for $10 or less

Q: 5. Does this lens take infrared picture or normal images? (I have seen review of this lens that takes normal images. is there a non infrared version of the lens?)

A: This lens records both infrared and normal wavelengths of light.Most lenses are not corrected for infrared light.Which means if you set the focus on your lens for normal shooting it will be blurred or out of focus for shooting infrared.If you likewise set the focus for infrared and try and shoot the next day in daylight it will be out of focus again.This because infrared light focuses at different points in the lens than all the other wavelengths of light.What THIS lens does is it keeps you from having to refocus everytime you switch from shooting in normal light to nighttime infrared aided light.This is done using a IR coating to make sure the the wavelengths of light focus on the same point in the lens barrel no matter if its IR or not.Hope that helps anserw your question.23

Q: 6. Does this Infrared Remote work with the Pentax K-1?

A: Yes

Q: 7. What are its dimensions?

A: 2 x 1 x .3 inches.

Q: 8. Is it possible to use it with bulb mode?

A: Yes. Works on K-3.

Q: 9. I have a Pentax K-30. I bought this and cannot seem to get it to work if I'm standing behind the camera on a tripod. Am I doing something wrong or is there a better choice?

A: Yes, This remote is an IR trigger, which means it is line of sight. If you are behind the camera,, the camera does not see the signal from the remote.Best way around this is to stand off to one side out of the field of view of the lens you are using.I have K3 and K20d bodies. My copy of this remote works with both.Hope this helps.JJ

Q: 10. Will this also work with the K70?

A: Yes, this remote will function with the K70.

[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. 5

[39 mm] 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. 5

[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 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!!! 5

[Glass] Works great on full spectrum cameras. Lets you get into the deep infrared on 720nm or higher converted cameras. 5

[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!!! 5

[39 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. 5
