Key Considerations When Choosing a 50mm for Portraits:
* Aperture: A wider aperture (e.g., f/1.8, f/1.4, f/1.2) is crucial for creating a shallow depth of field (blurry background) that isolates your subject. Lower f-numbers (like f/1.2) will give you a shallower depth of field but are also more expensive.
* Sharpness: While a little softness can be flattering in portraits, you generally want a lens that's sharp enough to capture good detail.
* Bokeh: The quality of the background blur (bokeh) is important. Look for lenses that produce smooth, pleasing bokeh without harsh edges or distracting patterns.
* Autofocus: Fast and accurate autofocus is essential for capturing sharp portraits, especially when shooting moving subjects or in challenging lighting conditions.
* Build Quality: If you plan on using the lens frequently, a more robust build quality will be important for durability.
* Budget: 50mm lenses range in price from under $150 to over $2,000. Determine your budget and choose the best lens you can afford within that range.
* Camera System: Make sure the lens is compatible with your camera system (Canon EF, Canon RF, Nikon F, Nikon Z, Sony E, etc.).

Before you buy:
