Canon 40D vs Canon 50D Comparison Overview

In this review, we will be comparing 40D and 50D, two Advanced DSLR cameras by Canon. Canon 40D was introduced to market in October 2007 and Canon 50D was launched in October 2008. There is 12 months difference between 40D and 50D so we don't expect to see a huge technology difference between these two cameras but it would still give an advantage to younger 50D, especially in sensor tech.

40D and 50D are members of Canon's EOS X0D series of cameras. Below you can find the latest models from this series.

Here is a brief look at the main features of Canon 40D and Canon 50D before getting into our more detailed comparison.

Canon 40D vs Canon 50D: Physical Specs and Body features Comparison

Size and weight is a big decision factor when you are trying to find the ideal camera for your needs. In this section, We are going to illustrate Canon 40D and Canon 50D side-by-side from the front, back and top in their relative dimensions. Canon 40D 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]. 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 Canon 40D and Canon 50D. In this case, we can see that Canon 40D and Canon 50D have the exact same height, width and thickness.

Here is the back view size comparison of Canon 40D and Canon 50D.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Canon 40D and Canon 50D have exactly the same weight of 822g.

Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since both Canon 40D and Canon 50D have the same Canon EF/EF-S lens mount and APS-C sized sensors, lenses will not be a differentiator on total size of the system.

Weather Sealing

Both 40D and 50D have weather sealings in their body, making them resistant to water and dust.

Canon 40D and Canon 50D's LCD screens has the same diagonal size of 3.00".

Canon 40D vs Canon 50D: Sensor Comparison

Canon 40D has a 10.0MP APS-C [22.2 x 14.8 mm ] sized CMOS sensor . On the other hand, Canon 50D has a 15.0MP APS-C [22.3 x 14.9 mm ] sized CMOS sensor and features Digic 4 processor.

Canon 50D's sensor provides 5MP more than Canon 40D's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely. On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.

Below you can see the 40D and 50D sensor size comparison.

Canon 40D and Canon 50D have almost the same sensor size so none of them has any significant advantage over other in providing control over depth of field when used with same focal length and aperture.

Both Canon 40D and Canon 50D sensors have been tested by DxoMark. DxoMark scores camera sensors for color depth [DXO Portrait], dynamic range [DXO Landscape] and low-light sensitivity [DXO Sports], and also gives them an overall score. Of the two cameras that we are comparing, 40D has scored 64, 1 points higher than 50D.

Canon 40D vs Canon 50D Comparison of Available Lenses

Number of available lenses is a big decision factor while choosing your interchangeable lens camera. Canon 40D and Canon 50D have the same Canon EF/EF-S lens mount and currently there are 333 native lenses available for these cameras.

Another important factor is the availability of image stabilization. None of these bodies have sensor based image stabilization so you have to buy lenses with Optical stabilization feature. Currently there are 113 lenses with Image stabilization for Canon EF/EF-S mount.

Here are some of the most popular Canon EF/EF-S Mount Lenses on Camera Decision:
