How many Megapixels does the Canon T7i have?

The Canon EOS Rebel T7i is equipped with a an APS-C sensor that offers an image resolution of 24 megapixels (MP), or 24 million pixels. With its native aspect ratio of 3:2, the sensor has 6 000 horizontal pixels and 4 000 vertical pixels.

A 35mm film slide or negative contains 5-15 MP of useful detail, so that the Canon T7i can be considered to be a high-resolution camera that outresolves any 35mm film camera.

A high megapixel count makes it possible to crop any captured image substantially or to make very large prints from the image file. On the downside, large megapixel files are slower to transfer and take up more storage space on the computer harddisk. Also, high-resolution imaging requires sharper, more expensive lenses than low-res picture taking.

How large can I print with 24 MP?

The maximum print size of the Canon T7i for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. Few people actually print their images that large on a regular basis, but it is nice to have the option to make very large prints of exceptional shots. Also, as mentioned earlier, a key advantage of high-MP cameras is that it is possible to crop an image ex-post and thereby, for example, change the composition of the capture or zoom in on some detail.

Sensor specs and performance

The table below compares the sensor specs of the Canon T7i to those of several similar cameras. In addition to sensor class and megapixel count, DXO values are reported as indicators of the sensor's imaging quality (higher is better). Three aspects are covered: color depth (DXO Portrait), dynamic range (DXO Landscape), and high-ISO noise (DXO Sports). Larger sensor cameras tend to outperform cameras of the same generation that are equipped with a smaller imager. On the other hand, larger sensors are more expensive and require bigger and heavier lenses than smaller light receptors.
