Sony cameras have history of problems with focusing when shooting at small apertures.

First they didn't open aperture to focus resulting in misses. Then A7RIV added an option to open somewhat up but it also added some lag and canceled depth of field preview because the aperture closed (slowly) only for the shot: https://m.dpreview.com/reviews/sony-a7r-iv-review/7#aperture_drive

What is A1 like in this aspect? Is the aperture drive faster than with A7RIV? Is aperture in focus priority open all the time or only for focusing?

I've shot over 60,000 shots with my a1s, with the following lenses:






600GM with and without 1.4x and 2.0x teleconverters.

I've NEVER experienced focusing delays. I'm typically shooting at f/8, but go up to f/11 for DOF on some close subjects and f/16-f/22 for sun stars.

I never had such problems with my a9 or a7RIII either. As a wildlife photographer, I rely on fast AF capture and tenacious tracking. I'm almost always in AF-C mode, with one of the "Tracking" modes selected, depending on the subject.
