I've been trying to hone my IR chops and took a hike into the C&O canal area in Maryland when I came across this short footbridge. Monochrome infrared with 720 nm filter. Fuji GFX w/ 20-35 zoom, I think at about 27mm.
Nice! I've heard some good but inconclusive things about the 20-35 and IR. What aperture? Have you noticed any focal length/aperture pairs with obvious hotspots on the 20-35?
I probably took about 20 or 30 frames and saw no apparent hot spots with the 20-35. However, I wasn't shooting into the sun or a large bright area. I've had absolutely no issues with the 45-100 either.

Great, thanks. Yeah I've heard from multiple sources the 45-100 and 100-200 have no hotspot issues at all. Seems the remember the 35-70 is pretty useable as well.
Yes and I've also heard that the 45 is particularly good. I have the two zooms because they're both 82 mm and I'm using the magnetic filters with a full spectrum GFX 50 S. It's a lot easier to experiment and a quick change of the filters. The only one I have that's screw in is the IR chrome from Kolari as they do not make a magnetic version.

Yeah I've heard the 45 is great as well. Kolari makes magnetic filters that "clip in" inside the mount and in front of the sensor now.
Yes, but you have to remove the lens and expose the sensor to the elements when you are shooting. I didn't like that idea and the clip in filters are very expensive.

They are pricey as filters go. But you only have to change the filter when you change the spectrum you are filtering on. Otherwise they work for all your lenses and actually protect the sensor. I've been using and STC Optics clear clip in filter for a couple of years with no issues/reflections or whatnot since I frequently change lenses in windy conditions and used to sometimes have issues with sensor/pollution.
For myself, I find it very easy to snap the filter on the front of the lens when I want to change the effects which I do frequently. I got the magnetic filters from life pixel and they're excellent glass with no issues. So everybody's got a comfort level, and that's the way they should work.
