Yeah, all Olympus OM lenses afaik can be set anywhere between f numbers
which makes for an infinite number of f stops.

|
| I don't think it really is more flexible. Just the opposite really. I have
a
| manual macro flash setup that takes advantage of the ability to set the
lens
| to 1/3 and 2/3 of the way between stops. (This is admittedly NOT with a
| 28/2.8.) Half-stop presets would not be helpful to me.
