I spent a day wandering New York City with a manual 35 mm lens, the Meike 35mm f/1.4, on my Canon M5. Kind of like wandering around with my old AE1 and its 50mm lens except I got to see the results much faster. I tried lots of zone focus and was often shooting from the hip pointing the camera in the general direction. Didn't always work but I did get some good shots that way.

Most of the outdoor shots were around f/16, the indoor ones f/4 - f/8, and the high bokeh ones around f/1.4 - f/2. Can't really tell since the lens isn't indexed for real details and its aperture setting has no clicks to see where you are in between the indexes it does have.
