How does IR work with an unmodified M10M? Seems like the IR filter works more like a dark red filter here. Is the M10M receptive for IR light, or is there an ICF cutoff filter in front of the sensor like in the regular M10? I remember the M8 was IR-receptive. The blocked IR rays would explain why foliage remained black in your photos but the sky turned out contrasty with the clouds. Beautiful shots!
From the few shots taken it is far less receptive than the M246 or M243. The earlier UV shot of the dandelions I used a UG11X filter which leaks some IR light and I noticed there was less IR leak around the dark portion of the centre of the dandelion. I need to test the M10M with my Coastal Optics 60 and Nikkor 105UV for IR tests which were my go to lenses on the M246 when shooting IR and UV as they lack coatings to eliminate IR and UV. At this point I can say it still does UV but less than M246 and it appears IR is very little. I agree the 092 acts more as a deep red filter. The Coastal Optics with the B+W 092, 093 filters plus the collection of Heliopans I have from RG645 up through RG100 which will give a true indication of IR reception but I don't anticipate that much IR. The sensor seems to be limited in the IR range.
This shot was with a Nikon 28 Series E + Singh-Ray IRay infrared filter attached. The two deciduous trees in the background came through much better then again the grass and evergreen trees had little IR reflectance. The tree in the foreground is expected to be white as it is flowering.

Thanks so much for the great explanation! Any kind of IR-filter (or IR-transmission lens) won't help you if the sensor stack design includes an IR-reflective ICF layer. That's the culprit of modern digital cameras that they always come now with a severe ICF layer to block IR light that colors look better - that's why any kind of IR filter in front of the lens doesn't help either. Of course on the M10M such IR-blocking layer on the sensor might be used to avoid IR light making things look unexpectedly brighter or darker for regular B&W photography.
Interesting to know that there is some transmission of UV light to the sensor.
This amazing 9 year old has been heavy on my mind today. This morning there was some good light coming in so I put this together. I am very close with her family. I've posted a few other photos here with her in mind...she is fighting brain cancer that made it's presence know quite abruptly and violently. Cancer sucks!
Is there a way to filter to only see images for a certain M. Like today Im not interested in seeing X2 images or Q, but M8 but tomorrow The CL could be interesting?
