I'd say f22 isn't traditional on fixed lens rangefinders...but oh well, exception make game more enjoyable.
f1.4 and f22 on same camera make no sense, at least for me.
One extreme designates camera as low light tool, another - as daylight carry-around, especially for beach (bad idea, anyway) and snow activities. Bright sunny days in South. Something like that. And now imagine gentleman wearing same tux for a party and sports or fishing? 🙂
For f22 there's Lynx 5000, add it's 1/1000 - I don't know if it were marketing trick to separate this models, but they are very logical. Maybe there are also rules of optics behind this - Lynx' 1.4 lens is optimized for large apertures, so while one can use it in situations demanding f22, there's no real reason do so.
Though, good ND4/ND8 filter will help to shoot wide open in daylight for that crazy DOF and bokeh.
