Canon Rebel T6s crops images?

 

Camera : Canon Rebel T6s
Lens : Canon EF-S 18-135mm
File : CR2 RAW file
Ratio : 3:2

Images are cropped both both the top & bottom sides.

Is this the camera's original design? or an issue?
Thank you.

That is just your thumbnail viewer and normal.

But the camera crops your image, that is correct, but from 6024x4022 to 6000x4000. From RawPedia:

 

"Demosaicing may rely on sampling the pixels which surround a given pixel. When demosaicing a pixel which lies at the top edge of the raw image, there are no pixels above it, thus it cannot be demosaiced in the same way and at the same quality as those pixels which are surrounded by a sufficiently large number of pixels. Most raw converters thus crop off a few rows and columns from around the image periphery, as does RawTherapee by default. However, you can override this cropping by manipulating the "border" value. Setting it to "0" means no cropping occurs, and RawTherapee will do what it can to demosaic the border pixels, though artifacts may appear!"

Thank you. It is well explained. Appreciate you assistance.

The default aspect ratio of the camera is 3:2.  This can be confirmed by viewing your images in the camera.  The areas that appear to be cropped in your screenshot are being created by whatever viewer you are using to preview the images.

Thank you. It is a relief to know nothing wrong with the camera. Appreciate.
