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 Sony A700 and Fujifilm A100 side-by-side from the front, back and top in their relative dimensions. Sony A700 has external dimensions of 142 x 105 x 80 mm (5.59 x 4.13 x 3.15″) and weighs 768 g (1.69 lb / 27.09 oz) (including batteries). Fujifilm A100 has external dimensions of 92 x 61 x 22 mm (3.62 x 2.4 x 0.87″) and weighs 124 g (0.27 lb / 4.37 oz) (including batteries).
Below you can see the front-view size comparison of the Sony A700 and the Fujifilm A100. Fujifilm A100 is clearly the smaller of the two cameras. Its body is 50mm narrower, 44mm shorter and 58mm thinner than Sony A700. As you can tell, actually this is not a fair size comparison since Fujifilm A100 has a built-in lens but Sony A700 doesn't. Once you put a lens on A700, its thickness will increase significantly.
Here is the back view size comparison of the Sony A700 and Fujifilm A100.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Fujifilm A100 is significantly lighter (644g ) than the Sony A700 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 A700, the total kit will weigh much higher.
Weather Sealing
With its weather-sealed body, we believe that the A700 has a big advantage over the A100 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Sony A700's 3.00" LCD screen is slightly larger than Fujifilm A100's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
