Hi there. My name is*****'d be happy to help you with this. You should definitely be able to crop your photos. You can do this from the Print Setting Screen on your camera. From the Print Setting Screen, select CROPPING. Set the cropping frame size , position, and aspect ratio using the options available on that screen.
Here is a link to the user manual for this camera.
The various options for cropping photos on your T5 are shown in detail on page 247. The manual is in pdf format and can be saved to your computer for later viewing.
Please give this a try and let me know how it works for you. If this solves the problem, would you mind taking a moment to rate my service? I'd really appreciate it!
