Size and weight are big decision factors when you are trying to find the ideal camera for your needs.

Pentax P70 has external dimensions of 97 x 54 x 22 mm (3.82 x 2.13 x 0.87″) and weighs 155 g (0.34 lb / 5.47 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Pentax P70 is significantly lighter (90g ) than the Samsung HZ30W which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Pentax Optio P70 nor Samsung HZ30W (WB600) 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
Samsung HZ30W's 3.00" LCD screen is slightly larger than Pentax P70's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
