We have found three early Olympus digital cameras that are capable of photographing auras. The earliest is the D-360L, which will produce tiny orb auras and does not even need a filter. My friend Kybob has made a video of this camera in action: https://youtu.be/USOH2GnspHg
Note that there is a vehicle in background in some of the shots, which will produce auras in its own right, being a substantial chunk of metal. This is the second video in a two part series. Part 1 covers the Canon camera: https://youtu.be/-4u9F3qOrmc
The other two cameras: D-490 Zoom and C-460 Zoom del Sol both need a filter. I am using 850nm, 90% pass filter material successfully in the Cokin Compact Camera holder: Amazon link: https://www.amazon.co.uk/Cokin-Digi-Holder-Cat-BAD700/dp/B0000AQ4N1/ref=as_sl_pc_as_ss_li_til?tag=trutreboo-21&linkCode=w00&linkId=4fb7b0a2b30130c6c5dd74146690004b&creativeASIN=B0000AQ4N1
I have just been informed that Cokin also make a magnetic filter for compact cameras: Amazon link: https://www.amazon.co.uk/Cokin-Magnetic-A-Holder-BA400MM/dp/B000T8Z3Y6/ref=as_sl_pc_as_ss_li_til?tag=trutreboo-21&linkCode=w00&linkId=ddc2a72f2e3b2827ca347a92d4405d6d&creativeASIN=B000T8Z3Y6
However, when I used a round filter on the D-490, attached to the front of the lens with poster putty, I found I needed a 950nm filter.
The orb auras become larger as the megapixels increase, the C-460 ZdS at 4.0MP produces the largest orbs of the three.
I haven’t tested all the early Olympus cameras and many can be bought so cheaply now, they may be worth buying just to test. Ideally look for one of the above models, which we know work. If you want to try another model, get one which has a viewfinder or viewing port as it is impossible to use the backscreen with an IR filter in front of the lens. I can tell you that I have tried the C-460 and D-545, which did not produce auras on my test site.
