Talking about "over the years".
I started with Shkolnik
in late seventies. It was mirrolress and next to shuterless and apertureless. My digital P&S which I'm using since 2003 and mirrorless as well.
Oh, but all of it is not the "state of the art mirrorless", even with Leica ASPH lens.
I guess, PePi is the place where art and gear come to joy we are recently searching here at RFF.
