Nice. That's what i expected, a heavy camera but still pocketable. Weight doesn't really matter much as soon as i can carry it around in my pocket. Thanks for the advice, i think i will get one in January or February.
They are pocketable, but you do neeed a lens cap any generic plastic push on cap will do, a filter is desirable and the lietz filters are the same push on size as the lens.
You will also need the lens hood, again a simple generic cap that fits the lens or the filter should fit the standard Lietz hood, as a hood cap.
The aperature setting ring allows slightly easier changing of aperature, without removing the filter and hood, reduces the risk of dropping the filter or hood.
I carry mine is a very small bag with filter. hood and cap in place, they are too heavy for other than a heavy coat pocket e.g. in winter when you want (need) to keep the camera above ambient.
But your mileage may vary
