F-Series Lens with MTF P-Line on PZ-1?

Just wondering what would happen if I set the default P-line of the PZ-1 as MTF, and later put an F lens on? Would it default to the standard P-line?

I think so, because MTF was a feature of the FA series.

But since the F lenses pass focal length data, you will get shutter speeds that try to follow 1/FL, right?

So it would be a touch different from P-line with an A lens... I think...

I won't necessarily try and follow 1/FL - the program for the SFXn had generic wide/standard/tele sub-programs so I suspect it would apply those. As mentioned, with the focal length, you'll get flash coverage warnings with some Pentax flashguns (and the built-in flash).

My recollection is that the lens is closed down two stops since most lenses perform well at that aperture ( maybe that is what the Pentax rep told me and I don't have any other information ).
