you'll need to do long exposures. also research your lenses, some let ir through unevenly across the frame (hotspots)

I used to use unmodified Sony NEX-7 for some IR work, but the exposure times were very long as the camera's IR filter cuts by far most of IR, thus a tripod was an absolute must. I imagine it's pretty much the same for A6000 as it's not likely that Sony has made the camera's IR filter any weaker as that would influence colour reproduction siginificantly (like with the fiasco called Leica M8).

So you need an aproperiate filter - that R72 is likely fine, a tripod and a lens which is decently corrected (+decent coatings) for the IR wavelenghts to avoid hotspots. I think you can google for a list of suitable lenses.

Great, exactly what I needed to know. The Hoya is one of the most used as far as I read. Yeah long exposures and a lense with no hotspot, I found a list somewhere with a decent amount of lenses listed.

I have a IR modified and Full spectrum modified A6000s. Check out some photos here: https://www.reddit.com/r/SonyAlpha/s/hkIPQvbwrr

I recommend getting a modified one online as the cost to pay someone to modify will be similar to getting a second hand modified one.

Like others said, without modification, you need really high ISO or long exposures.

I cant say for sure but I would assume so. My unmodified nikon Z6 works, and nikon uses sony sensors

When I needed infrared I bought an old used Canon DSLR and removed the filter from the matrix. That's what I call infrared! Would be good to combine with a filter that passes only infrared but I was happy with it anyway, summer trees were so pink!
