Thank you for using Canon products.
The feature guide description of the digital zoom function that appears on the LCD monitor of the EOS Rebel T3i may need to be clarified slightly. As such, we are considering revising this description.
When using the digital zoom, the image can be magnified while maintaining the full HD image size of [1920×1080]. However, because the image is processed digitally, the higher the magnification, the rougher the image will look. Please refer to p.152 of the user’s manual for full information about use of the digital zoom.
We are sorry for any confusion the current display may cause you, but we thank you for your understanding.
