Yes I still use the Ricoh. The first one to go would be the NEX-7, compared to both the Ricoh and the Sigma, fuzzy files, although there is a lot of room in PP. Actually the Sony files need the most PP of them all. But I like the EVF and focus peaking so much, so all cameras stay till may be the Leica M or some FF mirrorless alternative with EVF.
Kind regards, Michiel
