What are the differences between 50mm and 85mm lenses in terms of focal length and image quality?

A 50mm lens has a wider field of view compared to an 85mm lens, meaning it captures more of the scene in the frame. However, an 85mm lens provides a narrower field of view, resulting in a more zoomed-in and compressed perspective. In terms of image quality, 85mm lenses generally produce sharper images with better background blur (bokeh) due to their longer focal length.
