Example Concept: Prime lenses, such as 50mm f/1.8 or 85mm f/1.4, have larger apertures that allow more light to enter the lens, resulting in a shallower depth of field. This shallow depth of field blurs the background more effectively, creating a creamy bokeh that enhances the subject's separation. The optical design of prime lenses often includes elements that minimize aberrations, contributing to smoother out-of-focus areas.
