The Canon Rebel T5i DSLR is a digital still camera that can also shoot high-definition video. It features interchangeable lenses that can range from about 8mm to over 300mm. Recording video with DSLRs is becoming more and more popular because of the lenses that can be used and the ability to use shallow depth of field to separate the background from the subject.
As with digital still photography, you have all of the creative control of shutter speeds and apertures, as well as film speed control (ISO settings). You also can use several metering types as well as different white balance settings to control the look of your photos or video.
