As I mentioned earlier, the USB leads to inefficiency so just link the cell directly Is fine. This guyís 3D printed contraption is pretty much what I wanted to do. He is amazing. He put a compartment in the right hand grip to hold an IR remote with a trigger. The left handle cylinder to hold a very generous 3000mAh power cell. Twitter

Not expensive at all given the frequency of use I have gotten out of it due to its small size to carry on trips TOGETHER with a handful of lenses. Barely an inconvenience. The 08 I finally managed to pick up used and glad I have it at hand. Worth it!

The 72mm is more readily available and yes will work with many more lens / camera body combo options and also give you more area around the sphere to frame without vignettes. 52mm on the other hand is ideally sized for my Q series cameras, hence gets to come out with me on my travels far more often than the 72mm soratama does.

IR infra red conversion for Pentax Q cameras

Using a Pentax 02 lens and the Hoya R72 on my Q without the IR cut filter. Will have some other IR pass filters to try out soon.




A surprise finding. Same 02 lens but this time with a cheap variable ND when set to max by eye looks black, blocking out the visible spectrum but I found it is actually still letting through IR! The output is pretty stark. Quite handy being able to change the strength of the IR effect with a quick twist of the front filter vs swapping in a dedicated IR filter like the Hoya R72. Maybe some polarisation is happening to the IR too and perhaps not the best way for an IR pass, but at a pinch itís a neat trick!


Taken with variable ND at max.


Turning a variable ND to control IR!

Show us a pic of your CS mount and lens combo.

BTW I have a new tip to greatly reduce and dampen any unwanted wiggle space between the camera body and a body cap. Use a small thin hair band elastic. Colour of your choice. Just Wrap it around the bayonet of the bodycap. I can now happily adjust focus and aperture without the bodycap shifting around excessively.

Unmounting the lens is fine, the hair band stays gripped on the lens end of the bayonet.

IR infra red conversion for Pentax Q cameras

Adding back a pane of 0.5mm ordinary glass works to restore AF to infinity in IR tested positively on my 01, 02 and 08 lenses. Expect that other Pentax Q lenses will also be fine to focus to infinity in IR now. However... I can tell that some AR multicoated glass will be even better.
Would love to try this Q on UV photography/video too but a lot more costly for the right UV filter.

The rubber gasket is under the glass and I put back the frame on top. Just taped it to the front of the sensor box temporarily.

Rainy days prevent me from getting more sample IR shots using native Q lenses.

@geo444 admit the camera body was pretty filthy and without a body cap when I received it. Lord knows how long it was left exposed like that and the environment it was in. However, once inside the opened up sensor box, the sensor itself under the IR cut was fresh and spotless! I want to keep it that way for as long as possible. What do you do to keep it clean?

1st thought is to lay clean glass on top of the sensor box so keep parallel with the sensor. Will find out this weekend as I have some 0.5mm thick glass coming in that I will trim to fit. Fingers crossed.

Further notes.
Whilst lifting out the IR cut glass, you will feel the ribbon cable tethered to the bottom. Due to the awkward placing, I could not find a way to cut it off neatly and ended up gently tearing it off the glass instead. I donít see any resulting error messages when activating the dust shake, which of course is in any case rendered a useless feature after this mod.

Without replacing the 0.6mm thick IR cut glass, 01 and 02 lenses wonít AF/manual focus to infinity any more. However my modded infinity focusing Pentax 07 shield mount looks ok with itís usual signature blurry edges, only now with IR! Added a Hoya R72 filter screwed to front to get rid of some visible spectrum. Did a fresh custom white balance and the live view becomes semi monochromatic. Some blues showing through. ISO 125, 1/100s handheld lunch break shot.

I am still looking for some ordinary glass to replace the removed IR cut glass. Hopefully it will result in my AF enabled PQ lenses to be able to focus to infinity in the IR spectrum. Not so keen on the alternative to shave the mount thinner if I can avoid it.

I hope this helps others get into fast shutter IR on a Q! No need to smash any glass and no complex disassembly and reassembly of the Q and Q10. For a quick full spectrum mod, all you need is a sharp hobby knife. Would not surprise me if the Q7 or Q-S1 would be very similar.

Pentax Q, Q10-IRcut, most Sensitive Sensor ILC
Successfully modded a spare Q by removing itís IR cut filter glass. Thanks again to goe444ís very detailed instructions that gave me sufficient confidence to proceed.
It wasnít difficult to perform. Use folded bits of paper post-it notes to steady the sensor box. Use a fresh sharp hobby knife blade.The plastic is softer than I thought it would be. Score it a few times till you feel it pop through. If I were to do it again I might be able to preserve more of the bottom lip of the sensor box frame. I would also have at hand some glass to cover up the sensor ASAP after removing the ir cut filter to reduce chances of contamination.
The rubber gasket under the ir cut filter is not glued in place at the base but lightly adhered to the glass.

As this point the camera is full spectrum, taking in a mix of both the visible and IR light.
