This is a very handy means of controlling the camera wirelessly from a computer, tablet or smartphone. Also new is the integration of the WiFi module. ISO sensitivity covers a range from 100 to 12,800 in automatic mode, and reaches 25,600 in manual mode. The APS-C sensor used in the Canon EOS 70D is also a new feature. Nevertheless, we found the touchscreen to be very useful when configuring the network during operation and especially when controlling the camera from the computer. In microscopy, any contact with the camera should be avoided in order to preclude vibrations and motion blurring. While this feature is indeed a development, it is not relevant for the highly specialised mode of use in microscopy. This is an innovation that has been taken over from the Canon EOS 700D and 650D. As was the case with the predecessor model, the Canon EOS 70D has a tilting and rotatable screen which is also touch-sensitive. Both models fit well in the hand and weigh about the same amount ( 755 grams without the lens). Looked at from the outside, there is no evident difference from the predecessor model, the Canon EOS 60D. We were especially interested to see whether there were any significant innovations in comparison with the predecessor model that were also relevant for microscopy applications. Externally, the two models are very much alike.
