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 FH8 and Canon ELPH 510 HS side-by-side from the front, back and top in their relative dimensions. Panasonic FH8 has external dimensions of 96 x 57 x 19 mm (3.78 x 2.24 x 0.75″) and weighs 123 g (0.27 lb / 4.34 oz) (including batteries). Canon ELPH 510 HS has external dimensions of 99 x 59 x 22 mm (3.9 x 2.32 x 0.87″) and weighs 206 g (0.45 lb / 7.27 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic FH8 and the Canon ELPH 510 HS. Panasonic FH8 is clearly the smaller of the two cameras. Its body is 3mm narrower, 2mm shorter and 3mm thinner than Canon ELPH 510 HS.

Now lets look at the top view comparison of Panasonic FH8 and Canon ELPH 510 HS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic FH8 is significantly lighter (83g ) than the Canon ELPH 510 HS which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Panasonic Lumix DMC-FH8 nor Canon ELPH 510 HS (IXUS 1100 HS) 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
Canon ELPH 510 HS's 3.20" LCD screen is slightly larger than Panasonic FH8's 3" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
