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 Olympus FE-5010 and Panasonic G1 side-by-side from the front, back and top in their relative dimensions. Olympus FE-5010 has external dimensions of 96 x 57 x 21 mm (3.78 x 2.24 x 0.83″) and weighs 130 g (0.29 lb / 4.59 oz) (including batteries). Panasonic G1 has external dimensions of 124 x 84 x 45 mm (4.88 x 3.31 x 1.77″) and weighs 360 g (0.79 lb / 12.70 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus FE-5010 and the Panasonic G1. Olympus FE-5010 is clearly the smaller of the two cameras. Its body is 28mm narrower, 27mm shorter and 24mm thinner than Panasonic G1. As you can tell, actually this is not a fair size comparison since Olympus FE-5010 has a built-in lens but Panasonic G1 doesn't. Once you put a lens on G1, its thickness will increase significantly.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus FE-5010 is significantly lighter (230g ) than the Panasonic G1 which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on G1, the total kit will weigh much higher.
Weather Sealing
With its weather-sealed body, we believe that the FE-5010 has a big advantage over the G1 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Panasonic G1's 3.00" LCD screen is slightly larger than Olympus FE-5010's 2.7" screen.
Moreover, Panasonic G1 sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over-the-head levels, and especially very useful for shooting selfies and video. On the other hand, Olympus FE-5010 has a fixed type screen which provides almost no flexibility in shooting positions compared to G1.
