Well, it is certainly looking like focus hold button is found on the lens, not on the camera, but I don't know about the percentage of lenses that have this button. The DT 16-50 f/2.8 SSM that comes with the A77 does not have it.I am 99% surethat the "Focus Hold Button" is on many (but not all, and mostly heavier) Sony lenses.
I do want to state for the record that I searched. I found a zillion threads but most of them seemed only to have the word "focus" in them. The main hit was one that talked about focus hold as a feature on lenses but didn't (at that time) seem to address the questions I raised in my original post, which arose from the fact that there's a setting fro this in the camera and it's referred to in the camera manual. I thought focus hold on the button must be something different.
Look at the button at the bottom near the lens mount... that is the button being mentioned in the manual.

No, it is not. That is the "Preview Button". The Preview button is located on alpha camera bodies. The "Focus Hold Button" is located on some Sony (and iirc Minolta) alpha lenses.Look at the button at the bottom near the lens mount... that is the button being mentioned in the manual.
No. That's the "Preview Button". The Preview Button is not the same as the Focus Hold button.
And unless things are dramatically different in that regard from my A55, that menu option will allow switching functionality of that little button on the camera body between "Focus Hold" and "Aperture Preview".No, it is not.

Not, afaict, on the a77. The options for the Preview Button (viz.: the button on the camera body) are:
Can you double-check? The a77 does NOT work that way. The "focus hold" function is not assignable to the Preview Button. I have confirmed this with both the a77 manual and Gary Friedman's excellent guide.And unless things are dramatically different in that regard from my A55, that menu option will allow switching functionality of that little button on the camera body between "Focus Hold" and "Aperture Preview".No, it is not.

No. The manual distinguished between the Preview Button (mentioned on 9 pages in the a77 manual) and the Focus Hold Button (mentioned on 3 pages in the manual).
That is how it works on A55. The DOF Preview button can be set to Focus Hold. And if the lens has Focus Hold button, the same setting (as in the body) is inherited. A77 appears to be different.Can you double-check? The a77 does NOT work that way. The "focus hold" function is not assignable to the Preview Button.

The a33/a55's Preview Button does NOT function the same as the a65/a77.
Could you please confirm this as well? According to the Sony a55 manual, the Preview Button's sole function is DoF preview. There is no mention of using the Preview Button to hold the focus.
Again, according to the manual, there is a menu settings for the Focus Hold Button, but there is NO setting for the Preview Button.
So I've been misusing the button, thinking I was getting a DOF preview all along, when it was previewing more than the DOF... Hmm, maybe that explains why the DOF preview always looked a little odd.
And, now I'm wondering what the difference is between the DOF preview and the aperture preview?Can you double-check? The a77 does NOT work that way.
