Important Considerations When Choosing a 50mm for Portraits:
* Aperture (f-stop): A wider aperture (f/1.8, f/1.4, f/1.2) is generally preferred for portraits because it allows for a shallower depth of field, blurring the background and isolating your subject.
* Sharpness: You want a lens that is sharp, especially at wider apertures, but sharpness isn't everything. Sometimes a slightly softer lens can be more flattering for portraits.
* Bokeh: The quality of the background blur is important. Look for a lens with smooth, creamy bokeh.
* Autofocus: Fast and accurate autofocus is essential for capturing sharp portraits, especially if you're shooting moving subjects.
* Build Quality: A well-built lens will be more durable and reliable.
* Budget: Determine your budget upfront, as prices can vary significantly.
* Camera System: Make sure the lens is compatible with your camera system (Canon EF, Nikon F, Sony E, Fuji X, etc.).
* Manual Focus: How often do you plan to manually focus? Some lenses have nicer manual focus rings.
General Recommendations:
* Best Overall (Money No Object): Sony FE 50mm f/1.2 GM (for Sony), Nikon NIKKOR Z 50mm f/1.2 S (for Nikon), Canon RF 50mm f/1.2L USM (for Canon), Sigma 50mm f/1.4 DG HSM Art (for various systems)

Before you buy:
