If you want the smallest 35mm with all those features, you must be looking for an OM4T with the associated small lenses, The 110 cameras are smaller, but getting common batteries are the least of your problems!
Smallest practical system will be Olympus OM's. They're compact and reasonably quiet.
The Pen F is more compact but the sound is sharper & IMO noticeable. It's also 1/2 frame
so to get a similar size enlargement the grain would be more obvious.
Effective focal length of the lenses will be different be cause of the smaller format the same
as digital sensors.
My OM-1 and OM-4 are both smaller than my Contax 139Q, and the OM-1 weighs one ounce less with the winder-2 attached compared to the Contax with winder. If the 110 format was still viable, then the Pentax 110 would far and away beat almost everything on the market.
