I bought the K-01 back in 2012 when Pentax discontinued the camera and
liquidated their inventory. For a few years it was my studio macro
camera - comparable to the K5 in IQ but with focus peaking for macro
work. But the K01 has been pretty much idle for the past several years.
The IR conversion is the 720nm "standard" conversion. You can get some
color out of it, but not as much as as a 590nm filter. The blue and
pink tones come from a custom white balance setting using green foliage
as a reference and then swapping the red and blue channels. The one
surprise with the K-01 is that it loses 2-3 stops of exposure after the
conversion. I don't recall that with my old ir K-10D and a Nikon P6000 I
had converted a few years ago actually gained several stops of speed
post conversion.

My latest enablement - infrared converted K01:

I've wanted to get back to a larger sensor digital IR camera since my K-10D
started acting up. The K01 is perfect since it is mirrorless and both focus and
exposure are directly determined by the sensor using the actual IR light. The
K01 sensor is also very good, almost on part with the K5. Pluis - already
owning one also made it an easy decision. The only concern I had was using it
outdoors - in bright light I can't see the LCD well enough to compose. The
solution was an inexpensive Xit LCD loupe which makes for an excellent finder.
Very cool. Did you buy it converted or did you have it converted.
In the image the camera is fitted with the 18-55 f3.5-5.6. I've since been
using it more with the 17-70 f4. Both lenses have modest IR hot spots but are
pretty good.

Very nice images. I don’t remember having quite that color cast for the short
time I had an IR enabled K-5, did yours just have the IR blocking filter
removed?
I still have a bunch of IR pass filter plastic that I bought for making filters
for my studio strobes, as well as speedlights. If you want some for making an
IR flash, send me a message offlist. Another cool toy I have is an array of
IRED that I can use for doing video in infra red without blinding people.
Since I hacked that together ten years ago, it turns out that they have become
commercially available, such as this one:
