Canon SX1 IS has a Fully Articulated 2.80-inch LCD screen with a resolution of 230k dots. Articulated screens are more video oriented compared to only tilting or fixed screens. On the other hand, photography oriented users generally prefer tilting screens. At only 2.8", the screen is on the smaller side and 230kdot resolution is lower than most of the recent models in this class.
For those of you who loves shooting selfies, self or group photos, Canon SX1 IS will make your life easier with its Selfie friendly screen. Another group of users who will take advantage of SX1 IS's LCD screen are Vloggers and any video creators who are working in a single-person setup.
SX1 IS has a built-in Electronic viewfinder, making it easier to shoot in direct sunlight and in other situations where it might be difficult to view the LCD monitor.
