I don’t have any problems with a couple of t-mount lenses I have letting me enter the focal length on my K1. Maybe it’s characteristic of your particular adapter? I’m using a cheap eBay thing...
But I thought focal length was essential to allow the camera to know how far to move the sensor over a given time...

Sorry - yes, of course the FL is necessary, in order to know how fast to move the sensor.
I tried shorting out the contacts with aluminum foil, but no matter how I tried covering the contacts, the cam never asked for FL, and the menu setting for selecting FL never enabled.
Others have said that the K-1 does not have this problem, but all I know for sure is that with my K-70, even with the latest firmware installed, I cannot set the FL for the OTA connected by a t-adapter.
