645DF and P25

Good evening,

Will the PO 645DF work with the P25 back? Would firmware need to be updated?

Thanks

Hi

This should work just fine.
An older unit like this would be what we call "legacy mode"
This mean that you can shoot with it just fine but there is a couple limitations compared to newer back.
Flash sync with LS lenses will only be 1/800 compared to 1/1600 with newer backs.
When tethered you can not change aperture and shutter time.
But you can still trigger camera and change ISO
