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 Canon R10 and Sony A850 side-by-side from the front, back and top in their relative dimensions. Canon R10 has external dimensions of 122.5 x 87.8 x 83.4mm (4.82 x 3.46 x 3.28 and weighs 426 g (0.94 lb / 15.14 oz) (including batteries). Sony A850 has external dimensions of 156 x 117 x 82 mm (6.14 x 4.61 x 3.23″) and weighs 895 g (1.97 lb / 31.57 oz) (including batteries).
Below you can see the front-view size comparison of the Canon R10 and the Sony A850. Canon R10 is 33mm narrower and 29mm shorter than Sony A850 but it is also 1mm thicker.
Here is the back view size comparison of the Canon R10 and Sony A850.
Now lets look at the top view comparison of Canon R10 and Sony A850.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon R10 is significantly lighter (469g ) than the Sony A850 which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since Sony A850 has a Full frame sensor and Canon R10 has a smaller APS-C sensor, Canon R10's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sony A850 lenses.
Weather Sealing
Thanks to the weather-sealed body of the A850, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the R10.
LCD Screen Size and Features
Canon R10 and Sony A850's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Canon R10 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. Sony A850's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to R10.
