Just because your camera doesn’t use DOF scales, it doesn’t mean that they’ve all gone away. Olympus pro lenses use them.

I wonder why they don't put the DOF scale in the viewfinder or on the back LCD. The camera knows which distance the lens is focused at, it knows the focal length, it knows the aperture so it should be able to calculate the far and near distance.

So it’s not just me.

I’ve been playing on forums for 17 years and have nobody on ignore ... and I’m a member of about a dozen.

I don't recall ever having a zoom lens with a DoF scale. It varies based on Aperture, Distance, and Focal Length.

I remember the dof scale on lens but have haven't paid attention to them for so many years I don't miss them.
As far as I'm concerned Chris T is a non-person.

On a vivitar 28 -200 zoom there are a focal length scale which reveals itself as you extend the barrel there is a straight white line which lines up with the Aperture 2 blue curves kind of trumpet shaped for dof at f8 a red line this is for infra red. If you focus to the white line you need to compensate to be in focus in infra red and finally a pair of green curves which are the dof scale for f22.

There are of course just guidelines and out by around a stop for an aps-c sensor.

Thank you. I did have a Vivitar years back for a Spotmatic F, and it did have that scale. Most of my zooms today are internal and I forgot about the Vivitar. I forget a lot these days.

You mean you don't all memorize the DoF table?

The old push-pull type zoom lenses had DOF markings on the barrel. That went away with zoom rings, because there wasn't room.

I can't think of a reason why they don't have that feature on mirrorless cameras. My Panasonic bridge camera (FZ200) shows a dynamic DOF scale when manual focus is engaged; very useful when setting hyperfocal distance. I always thought it could use some improvement, like a distance estimation, rather than having it eliminated entirely with the micro Four Thirds models.

Gritty reality I can believe, truth is a more ephemeral concept!
