I just got a new Canon 17mm RF lens, and the lens does not have a manual-focus switch--you have to set that in the camera menu. The only time I might use this would be probably (sometimes) in macro mode (which not what I bought this lens for).

However this lens is generally in focus at any distance because the hyperfocal range is so vast. At f4, it is sharp from 2 meters out (focused on 4 meters).

Naturally I will be focusing on the main subject (auto or manually), but for walking around shooting scenes, wouldn't it be nice if wide angle lenses had three focus settings: manual, auto, and hyper-auto? This would set the distance according to the aperture selected (in Canon AV mode). Of course we can do this manually ourselves--if we happen to have a hyperfocal distance chart in hand; but I can't remember the whole chart, so auto would be brilliant. (Lenses that have hyperfocal ranges on the lens do this for manual use, but that feature went the way of manual focus lenses...) Photojournalism comes to mind--they often left a normal lens with press camera on f8 and had pre-set stops for close, medium, and distant pictures.

This should have occurred to lens makers, as they are always looking for ways to make lenses more expensive.

Yes - but it is cheaper to do it this way.

Wouldn't it be nice if we had world peace too?

In the meantime, learn and trust your auto-focus capable, mirrorless digital technology to quick grab and properly and accurately focus at whatever aperture you've selected.

Well, I thought autofocus was silly when it came out--we focused without thinking.

I wonder with your lens how accurate can you manually set the focus to say 2 meters (not puting a subject at 2m and focus on it).

Well, if I am presetting it, I can be as accurate as I like. I would err on the side of more focus range.

Then, use (buy) a manual focus lens and an adapter for the legacy mount to your RF body. Look at the results. Were (are) you really better in manual over AF? Consistently better? Even with multiple free attempts via "free" digital frames?

My experience in scanning old film negatives and shooting those same MF lenses on mirrorless is that my memory of great results fail to hold up under close scrutiny in 2023, especially when compared to either 2023 AF and MF results.

Oh, I like autofocus now.
But many people today seem to prefer manual exposure, yes?

Really how accurate? +/- 1 inch? I don't know how the distance scale on your practicular lens works but with most lenses I know presetting the lens to a distance is not very accurate.

Manual exposure and manual focus have nothing in common other than they both involve cameras.

In this group, there are many that prefer manually setting as much as possible.

I'm an outlier. I've gradually gone to using the camera's automation more. One of Sony's best settings is AUTO. It gives me more time to think about composition. I use it a lot and only use manual when it is necessary.

(a comparison on automation)

The proposal was for autofocus based on the aperture set, for hyperfocal distance when set for that... It would save calculating this at the time and setting it manually.
