The quality is OK for the choosen film. I didn't want to buy expensive film since I didn't know if the camera works fine or not. I shot Kodak and Fuji @ ISO200 so the grain is normal for that ISO and that film.
I don't want to buy Cinestill yet, and I have second thoughts for Portra too. The blur is actually the shallow DOF. I have shots that are sharper, but not macro.
I shot this at f2.8 and it seems that f2.8 on "Full Frame" is different than on crop.
