Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the Panasonic LX100 and Pentax X70 side-by-side from the front, back and top in their relative dimensions. Panasonic LX100 has external dimensions of 115 x 66 x 55 mm (4.53 x 2.6 x 2.17″) and weighs 393 g (0.87 lb / 13.86 oz) (including batteries). Pentax X70 has external dimensions of 110 x 83 x 90 mm (4.33 x 3.27 x 3.54″) and weighs 410 g (0.90 lb / 14.46 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic LX100 and the Pentax X70. Panasonic LX100 is 17mm shorter and 35mm thinner than Pentax X70 but it is also 5mm wider.
Here is the back view size comparison of the Panasonic LX100 and Pentax X70.
Now lets look at the top view comparison of Panasonic LX100 and Pentax X70.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic LX100 is 17g lighter than the Pentax X70 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-LX100 nor Pentax X70 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
Panasonic LX100's 3.00" LCD screen is slightly larger than Pentax X70's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
