The K-5 can store AF corrections for up to 20 individual lenses. What happens if you have 21 lenses?

Does the camera just remember the last 20 lenses you connected, and silently forget anything older than that? Or does it pop up some kind of secret display only for elite lens hoarders, congratulating you on your growing collection, and then allowing you to choose which ones you want to delete?

Thankfully I don't actually have these many AF lenses, and most of mine are dead-on anyhow. Looked in the manual but it doesn't say what happens.

I only have one lens that needs AF correction. If you have that many lenses that need correction, then you should send some of them in to be adjusted. Not all lenses need it. I doubt anyone has enough lenses for it to matter.

I'd suspect a fault with the body at that point, unless you had multiples of every lens and somehow had a rotation scheme so you used every one of them.

You should have a setting for "all" lenses as well as settings for the individual ones. I imagine lens #21 would probably get the "all" default.
