I'm looking for a camera which can be in my bag or pocket at all times. Being a user of medium format, I have never really looked into what is available on the market.
It must be 35mm.
Smaller than 10cm across would be nice.
Manual is preferred, especially for focus.
Flash isn't necessary, but useful.
Classic or modern (though secretly I prefer classic).
Good quality lens and mechanics a must.
But above all, it must be hard as nails and utterly reliable. Metal bodied especially.
Suggestions?
