Description by Canon:
18.0 Megapixel CMOS (APS-C) sensor
The EOS Rebel T5i features Canon's amazing 18.0 Megapixel CMOS (Complementary Metal Oxide Semiconductor) sensor. Perfect for enlargements or for cropping detailed portions of the composition, the camera's sensor captures images with exceptional clarity and tonal range. This first-class sensor features many of the same technologies used by professional Canon cameras to maximize each pixel's light-gathering efficiency and has center pixels that aid in the EOS Rebel T5i's accurate AF performance. This APS-C size sensor creates an effective 1.6x field of view (compared to 35mm format).
14-bit A/D Conversion
With 14-bit analog-to-digital conversion, the EOS Rebel T5i captures and records images with remarkable gradations and detail in subtle tones and colors, resulting in more realistic and detailed images. By recording up to 16,384 colors per channel, the EOS Rebel T5i ensures that the fine detail found in subjects like foliage, sky and water are preserved and recorded with a tremendous level of accuracy, ensuring gorgeous results.
ISO 100–12800 and expandable to 25600 in H mode
Thanks to its DIGIC 5 Image Processor, the EOS Rebel T5i features an expanded ISO range of ISO 100–12800 (expandable to 25600 in H mode) that makes shooting possible in situations previously unthinkable without flash. The EOS Rebel T5i, with the DIGIC 5 Image Processor's remarkable noise-reduction technology, performs brilliantly in low-light shooting. Used with one of Canon's EF or EF-S lenses with Optical Image Stabilizer, the EOS Rebel T5i can record beautiful images even when light sources are scarce.
DIGIC 5 Image Processor
The EOS Rebel T5i's DIGIC 5 Image Processor works with the camera's CMOS sensor to deliver images with incredible detail in more situations, without the need for artificial light sources. With the power of the DIGIC 5 Image Processor, the EOS Rebel T5i can achieve higher ISO sensitivity, can shoot up to 5.0 fps continuously and can even perform advanced functions like HDR Backlight Control, art filters, lens correction and much more. The camera's brilliant imaging core supercharges every facet of still and moving image capture.
The EOS 700D is easy to use from the moment you first pick it up. Shoot and focus with a single tap of the camera’s touch screen, and use pinch and swipe gestures to navigate when reviewing images.
