EOS Rebel T7i: Af Performance

Optical Viewfinder

Exactly Your Shot

Shooting with the optical viewfinder is fast, thanks to minimal shutter lag and 45-point all cross-type Optical Viewfinder AF* with phase-detection. It lets you see exactly what the lens sees in virtually every lighting condition, and allows you to hold the camera close to your body for extra stability. Focus points, exposure and other helpful info is overlaid onto the image.
