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 (138g ) than the Panasonic ZS1 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither Panasonic Lumix DMC-ZS1 (Lumix DMC-TZ6) nor Pentax Efina provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top Compact Cameras with Weather Sealing
LCD Screen Size and Features
Panasonic ZS1's 2.7" 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.
