AKA micro four thirds ISO 3200? Standard practice if you've used a camera ever.
Oddly high ISOs only look bad on high megapixel cameras regardless of sensor size. I won't deny that FF ISO 3200 looks better than MFT ISO 3200 or pretend equivalence means anything in 99% of real life situations. But if you have a high megapixel camera like an R5/A7RV/Z8 or XT5/R7 high ISO noise looks fucking terrible with horrid - sharper, but with nasty green blotches everywhere even after NR and more like sandpaper than film grain. On normal cameras high ISO noise looks a little soft and grainy but the colors are still good, like film.
This has the odd effect of the OM-5 being better at ISO 3200 than an A7RV or Z7II is at ISo 12800.
