Focal Length - Pentax K-7 Operating Manual

When the Focal Length Cannot Be Automatically Detected

such as focal length.
If the camera uses a DA, DA L, D FA, FA J, FA or F lens, the lens
information is automatically obtained when the Shake Reduction function
is activated.

turned on with [Shake Reduction] set to k (On) and a type of lens that
does not support automatic obtaining the lens information such as focal
length (p.292) is mounted.
Set the focal length manually in the [Input Focal Length] setting screen.

the [A Custom Setting 6] menu to [Permitted]. (p.294)
