More b/w follows ... IR view of "my" river. Viltrox 20mm f/2.8, modified Z5, Kolari 720nm clip-in filter.
Just a tiny detail mars the tranquil scene. Oh well. Man's impact is ubiquitous.
Very nice use of tranquil IR cloud reflections contrasting the grim tube feeding who knows what...
The clip-in filter caught my attention: Do you see any more problems with flares or wide angle corners performance (due to the steep angle caused by the close proximity of the clip-in filter to the lens rear element) than with an on-sensor of front mounted filter? I am thinking if a full-spectrum body can be combined as an extra visible light body with clip-in UV-IR cut (perhaps with Kolari's Nikon OEM filter offering), clip-in IR pass, and clip-in quartz protective window as base for UV (no UV-pass clip-in offered for that as I can see). Also is register distance adjusted to avoid problems with infinity focus due to different combined filter thicknesses behind the lens? Apparently what you have seems to work very well, but asking anyway. Ideally the IR-cut on the sensor would be removed and not replace with on-sensor quartz filter glass, but always be used with one type of clip-in or the other to replace it.
