How to adjust the hyperfocal distance of Canon 70d 18- 135 lens?

Your lens is EF 18- 135, and even the focus window is cancelled (Nikon lens is shown above, yours is not). There is neither focus scale nor depth scale, so I don't know where the "infinity" is in the strict sense. The aperture is also controlled by the fuselage, so it is difficult to observe from the viewfinder.

But in theory, when you hold the fuselage, the greater the amount of turning the focus ring clockwise (the lens is set to MF mode) and the shallower the depth of field, the greater the amount of turning the focus ring counterclockwise and the deeper the depth of field. Theoretically, we can get the maximum depth of field of the aperture at that time, that is, hyperfocal distance.

Of course, this time is not necessarily in focus, nor is it guaranteed to be a strict "hyperfocal distance", so there is still a little difference between the digital age and the use of film lenses.

In fact, it is recommended to use a smaller aperture directly and then focus clearly. Theoretical things can be understood.
