Having fiun changing/discovering lenses and using manual mode on GX7...
When I set the lens focal length...
If the 50mm lens is normally for an old 35mm camera do I input 100mm?
Thanks!

The only time I remember being given the option to set a lenses focal length on the camera is when mounting a manual focus lens - to set the IBIS appropriately.

You should always use the focal length written on the lens.

The focal length of a lens is a physical measurement of that lens, so a 50mm lens is always a 50mm lens, only different cameras will interpret that data differently - people then get very worked up on how to compare lenses between systems and how the different variables change.
