Which legacy Pentax lenses have corrections built in to the K-1?

K-1 has 14 legacy lens corrections. Anyone know which lenses?

Is it sad that I have all but one of those? Soon it will be time to dust them off!

Also, the DA* 200mm, DA* 300mm, and DA 560mm support lens corrections in full frame mode. Other DA lenses only have corrections in crop mode.

Not as sad as the fact that I have only one of those (FA 50)

Thanks for that list -- I really hope they allow these correction profiles to work on the K-3 too with a firmware update!

Adam, what about the FA 20/2.8? I would think this would be included also.

Adam, Looks like you are all set. I wish I had the collection you have. I do have the Three Amigos and the DFA 100 Macro. I would love to get my hands on a FA* 24. A friend of mine has one and I got to try it. It is a fantastic lens and would complete my prime collection for most of the work I do now.

Does anybody know if the new/current lenses have these corrections built into their firmware and communicated to the camera like the focal length, etc?
Or are they are of the camera firmware (which means older cameras can't correct new lenses unless a firmware update is released) ?

Great collection Adam. Two comments:

1. Yes, as previosuly mentioned, they need to add the FA20/2.8 to the K-1
2. Why not add the F series lenses to the K-1? I am biases as I have all of those except one

IIRC the FA's have something about their inbuilt circuitry that tells the camera stuff which the F's don't. Do correct me if I am mistaken.

I understood that the FA135mm had inbuilt circuitry for "future" camera functions. I vaguely recall something about MTF in relation to it. I assumed that at some point there would be a firmware function that would tweak settings having regard for MTF. But that is probably too simplistic as an explanation.

FA lenses and newer have info to support the MTF program line.
