I got out my Infrared-converted Olympus E520 that was purchased maybe 10-12 years ago. I kept the 14-54 (good thing). It’s got a bit of a hot spot, but that’s fixable. This camera was bought, off Ebay, I think, already converted when I had my E-1 or E-3, I can’t remember when. It looks like it’s a 820 nm cutoff filter. I shoot it in black-and-white and bump up the contrast in the camera. As long as the histogram shows that I”m not blowing the highlights, it’s all fixable in post.
