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 G1 and Kodak M530 side-by-side from the front, back and top in their relative dimensions. 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). Kodak M530 has external dimensions of 94 x 57 x 23 mm (3.7 x 2.24 x 0.91″) and weighs 150 g (0.33 lb / 5.29 oz) (including batteries).
Below you can see the front-view size comparison of the Panasonic G1 and the Kodak M530. Kodak M530 is clearly the smaller of the two cameras. Its body is 30mm narrower, 27mm shorter and 22mm thinner than Panasonic G1. As you can tell, actually this is not a fair size comparison since Kodak M530 has a built-in lens but Panasonic G1 doesn't. Once you put a lens on G1, its thickness will increase significantly.
Here is the back view size comparison of the Panasonic G1 and Kodak M530.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Kodak M530 is significantly lighter (210g ) 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
Unfortunately neither the Panasonic Lumix DMC-G1 nor Kodak EasyShare M530 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 G1's 3.00" LCD screen is slightly larger than Kodak M530'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, Kodak M530 has a fixed type screen which provides almost no flexibility in shooting positions compared to G1.
