There are many kinds of cameras: DSLRs, point and shoot, mirrorless, even that weird Sony F707 from when DSLRs started. But one thing almost never changed since when cameras started. Even the old Analog cameras. The Shutte Button. Sure, it was mechanical at first and got a new “half-press” when auto fucus was introduced. But the overall mechanics stayed the same. Click the button – make a photo.
In a patent application spotted by Canon News, you see something that resembles a touchpad. If you google translate the patent (like I did), you see that it does not just resemble a touchpad. It is a touchpad. Moreover, the back LCD has another touch screen, similar to what we are actually used to in recent camera lines.
