I'm still using my Action One and am quite happy with it.  There are times when I would like to go in a bit closer but not macro.  Is there a lens available that will allow focusing it to around 25cm?

try adding  crop in your post, A1 does no do  digital zoom 20-30% zoom in 4K and render to 1080P   or simply load 4K  no loss will be detected when most watch phone vids

Hi there. Thank you for reaching out. We don't have an available lens that can allow focusing your Osmo Action at around 25cm. But I hope you can get some awesome recommendations from this forum. Thank you for your understanding and patience. Have a great day ahead.

wow the actual  lens, and square sensor, was hte  way to change the lens, so this would also go for the DJI Action 3. no  outer lens swapping.   if that is their importance go for it but the camera becomes volnuable to water

I think it is easier to take a close up lens No 1 or 2
