Silly question but with an aperture of f1.8 what was the lens' focal lenght. Wide aperture to me is maybe 18mm on a FF camera. And I have yet to see an 18mm lens open to f1.8. If you consider a 35mm lens to be wide aperture then you need to consult your aperture vs depth of field chart to determine what is in focus. Because it's not evrything at f1.8...
