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 Nikon A100 and Sony TX200V side-by-side from the front, back and top in their relative dimensions. Nikon A100 has external dimensions of 95 x 59 x 20 mm (3.74 x 2.32 x 0.79″) and weighs 119 g (0.26 lb / 4.20 oz) (including batteries). Sony TX200V has external dimensions of 96 x 58 x 16 mm (3.78 x 2.28 x 0.63″) and weighs 129 g (0.28 lb / 4.55 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon A100 and the Sony TX200V. Sony TX200V is 1mm shorter and 4mm thinner than Nikon A100 but it is also 1mm wider.
Here is the back view size comparison of the Nikon A100 and Sony TX200V.
Now lets look at the top view comparison of Nikon A100 and Sony TX200V.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon A100 is 10g lighter than the Sony TX200V but we don't think this will make a significant difference.
Weather Sealing
Thanks to the weather-sealed body of the TX200V, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the A100.
LCD Screen Size and Features
Sony TX200V's 3.30" LCD screen is slightly larger than Nikon A100's 2.7 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
