Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax Efina is significantly lighter (64g ) than the Pentax P70 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Pentax Optio P70 nor Pentax Efina provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Pentax P70's 2.70" LCD screen is slightly larger than Pentax Efina's 2.5" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
