Canon 100D vs Canon SL3: 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 100D and Canon SL3 side-by-side from the front, back and top in their relative dimensions.

Below you can see the front view size comparison of Canon 100D and Canon SL3. Canon 100D is clearly the smaller of the two cameras. Its body is 5mm narrower, 2mm shorter and 1mm thinner than Canon SL3.

Canon 100D vs Canon SL3 Detailed Size Comparison

Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Canon 100D is 42g lighter than the Canon SL3 but we don't think this will make a significant difference.

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 100D and Canon SL3 have the same APS-C sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.

Weather Sealing

Unfortunately neither Canon EOS 100D (EOS Rebel SL1) nor Canon EOS Rebel SL3 (EOS 250D / EOS Kiss X10) provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections:

LCD Screen Size and Features

Canon 100D and Canon SL3's LCD screens has the same diagonal size of 3".

Canon 100D vs Canon SL3: Sensor Comparison

Canon 100D has a 18.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Digic 5 processor. On the other hand, Canon SL3 has a 24.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features DIGIC 8 processor.

Canon SL3's sensor provides 6MP more than Canon 100D'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 100D and SL3 sensor size comparison.

Canon 100D vs Canon SL3 Sensor Size Comparison


Canon 100D and Canon SL3 have sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Canon 100D has 33% larger pixel area compared to Canon SL3, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
