Key Considerations When Choosing a 50mm for Portraits:
* Aperture: A wider aperture (e.g., f/1.2, f/1.4, f/1.8) allows more light into the camera, enabling faster shutter speeds in low light and creating a shallower depth of field (more background blur or "bokeh"). For portraits, a wider aperture is generally preferred to isolate the subject.
* Sharpness: While sharpness is important, it's not the only factor for portraits. A lens that's *too* sharp can accentuate skin imperfections. Many photographers prefer a lens that offers a good balance of sharpness and a pleasing rendering.
* Bokeh: The quality of the background blur is crucial for portraits. Look for a lens that produces smooth, creamy bokeh without harsh edges or distracting patterns.
* Autofocus: Fast and accurate autofocus is important, especially for portraits of moving subjects (e.g., children).
* Build Quality: A well-built lens will be more durable and reliable over time.
* Price: Set a budget and find the best lens you can afford within that range.

Before You Buy:
