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 Samsung PL170 and Canon 50D side-by-side from the front, back and top in their relative dimensions. Samsung PL170 has external dimensions of 95 x 57 x 19 mm (3.74 x 2.24 x 0.75″) and weighs (including batteries). Canon 50D has external dimensions of 146 x 108 x 74 mm (5.75 x 4.25 x 2.91″) and weighs 822 g (1.81 lb / 29.00 oz) (including batteries).
Below you can see the front-view size comparison of the Samsung PL170 and the Canon 50D. Samsung PL170 is clearly the smaller of the two cameras. Its body is 51mm narrower, 51mm shorter and 55mm thinner than Canon 50D. As you can tell, actually this is not a fair size comparison since Samsung PL170 has a built-in lens but Canon 50D doesn't. Once you put a lens on 50D, its thickness will increase significantly.
Here is the back view size comparison of the Samsung PL170 and Canon 50D.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung PL170 is 822g lighter than the Canon 50D but we don't think this will make a significant difference.
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 50D, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the 50D, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the PL170.
LCD Screen Size and Features
Samsung PL170 and Canon 50D's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
