The EOS Rebel SL1 is built around version II of Canon's 18MP 'Hybrid CMOS' sensor, which has pixels dedicated to providing phase detection autofocus in live view and video mode. On the SL1 this focus capability extends to cover 80% of the sensor's imaging area.

The sensor is paired with Canon's DIGIC 5 processing engine.
The Rebel SL1's pop-up flash has a guide number of 9.4m, the same as the Rebel T3/1100D, but less powerful than the unit found on the T5i. Unlike the T5i's unit, this flash cannot wirelessly trigger external Speedlites. You can set flash exposure compensation of +/- 2 EV. Flash sync can be set at up to 1/200 sec. and when attaching an external Speedlite to the camera's hotshoe, flash settings can be adjusted via the rear LCD screen.
Openings for both a monaural microphone (top) and speaker are located on the far left of the camera's top plate.
The on/off switch has a third position which enables video record mode. The mode dial has icons evenly spaced around its perimeter and spins 360 degrees without the hard stop found on earlier Rebel-series models. Six scene modes are housed under the SCN icon.
On the Rebel SL1, Canon's familiar AF point and AF/AE lock buttons are vertically arranged, sitting along the far right edge of the camera body. The buttons also serve as image magnification controls during playback mode.
The movie record button is placed on the camera's shoulder for easy operation by your thumb. It only initiates recording when the power switch is set to video; in stills mode it's used to enter and exit live view.
The Q menu and 'Set' functionality share the same button, which is surrounded by a 4-way controller that can be used to navigate onscreen menus and options.

The delete button has a concave design that helps prevent accidental operation. To the right of this button you can see the card access lamp which indicates data being written to the SD card.
The top corner of the camera has a self-timer lamp, that's also used used to reduce the red-eye effect in flash shots.
The little black rectangle directly below the hot shoe is a proximity sensor that automatically switches off the rear screen when you're using the viewfinder.
Located along the side of the lens throat is the lens release and below it the depth-of-field preview button.
An infrared sensor is positioned on the hand grip so that the camera can be triggered remotely using the optional Remote Controller RC-6 unit.
The camera's inputs are housed behind a rubber flap on the left side of the camera. HDMI and USB ports sit beneath a 3.5mm stereo mic input and a jack for a cabled remote release.
The battery and SD card go into a compartment on the base of the camera. The Rebel SL1 uses the same 5.94Wh (7.2V 825mAh) LP-E12 battery introduced with the EOS M.
The tripod socket is placed in-line with the center of the lens. The camera's small size means it's fairly close to the base compartment door, so don't expect to be able to change either card or battery with the camera on a full-size tripod plate.
