"You have a 4mm lens at f/2. To get the same depth of field you'd need a 50mm lens at f/25, not f/512." Humorously years back I had authored a giant depth of field essay with online calculators specifically because so many people just couldn't understand why their iPhone couldn't get bokeh. Yes, f/512 would be the impossible equivalent. This is easily calculated. Regardless, the lens Apple uses for macro mode has a 1…
That's just not how lenses work, fundamentally. Bokeh is determined by two things, and two things only - the diameter of the aperture and the distance to the object. That's it. Also yes, the wide angle of the iPhone 13 is much smaller. Just stop down even further then. Cheap macro lenses in 2021 are typically around 24mm. I'm talking about the Mitakons and the Laowas of the world. Focus stacking is needed when you're…
Bokeh is the quality of rendering of out-of-focus highlights.
