Dating a canon camera

It isn't the newest SLR around anymore, having been replaced by the 80D, and it's been discontinued by Canon, but if you can find one, it's worth considering over some more recent models (see below).When we originally reviewed the 70D it cost £999 for the body only.The Beginners’ Course is aimed at those who have just bought their first digital SLR and who have been mainly using their EOS Digital SLR in Auto Mode.

This course covers the EOS 1Dx, EOS 5DS, EOS 5DSR, EOS 5D Mark IV and EOS 6D cameras.

However, previous implementations have been limited to a few dedicated phase-detect points dotted across the sensor.

What's special about the 70D is that almost every pixel can contribute to phase-detect autofocus.

Each pixel not only measures the intensity of light, but also the direction, with each one made up of two photodiodes facing left and right.

This helps the sensor to perform phase-detect autofocus, determining not just whether the image is in focus, but also, if not, by how much.
