Thanks for the quick response
Photos are being taken in a wide range on conditions. It seems the underexposure is consistent across all rolls and frames.
It seems very much like the information on the dials and the reader is not what is being implemented inside.

Hi Forum
I am a frequent user of my Pentax 645n.
I use in auto function and it has always been flawless.
However......
Recently got I back 30 rolls of portra 400 120 from a holiday and exactly half are dramatically underexposed.
There is an obvious day in which the metering shifts from perfect to very very wrong.
The mystery is all dials are correct - iso set to 400, all film used is 400, dials not shifted to minus anything
i have cross checked through lens meter readings with my Pentax 67ii and a light meter and the Pentax 645n is apparently reading correctly but results look 4 stops under.
It is not lens dependent either as I used two lenses through out the trip.
Please please help
any suggestions?
