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 FX48 and Ricoh GR Digital III side-by-side from the front, back and top in their relative dimensions.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.

Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-FX48 (Lumix DMC-FX40) nor Ricoh GR Digital III 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
Ricoh GR Digital III's 3.00" LCD screen is slightly larger than Panasonic FX48's 2.5" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
