The Sony RX100 lens is f/1.8 at the wide end to f/4.9 at the long end.
Results up to f/6.3 or so look reasonable with the Sony RX100 at the wide end at lesat. Then there are many shots which just don’t look sharp at all, even at the wide end of the zoom range, and the reason for this is not at all clear to me when I examine the images.
