Key Considerations for Portraits:
* Aperture: A wider aperture (lower f-number like f/1.2, f/1.4, or f/1.8) is crucial for portraits. It allows you to create a shallow depth of field, blurring the background and isolating your subject.
* Sharpness: Sharpness is important, but not at the expense of other qualities. A lens that is razor-sharp but produces harsh bokeh might not be ideal for portraits. Consider sharpness across the aperture range (wide open vs. stopped down).
* Bokeh: The quality of the out-of-focus areas (bokeh) is critical for pleasing portraits. Look for lenses that produce smooth, creamy bokeh without harsh circles or distractions.
* Autofocus: Fast and accurate autofocus is important, especially when shooting portraits of moving subjects (like children).
* Build Quality: Consider the build quality, especially if you plan to use the lens frequently. A metal build generally feels more robust and durable.
* Budget: Set a realistic budget and stick to it. There are excellent options at various price points.
* Camera System: Ensure that the lens is compatible with your camera's mount (Canon EF, Canon RF, Nikon F, Nikon Z, Sony E, etc.).
* Focal Length Preference: Some people prefer a slightly longer focal length for portraits (like 85mm), as it can be more flattering. However, 50mm is a versatile and classic choice.

Before You Buy:
* Read Reviews: Check out reviews from reputable photography websites and magazines (e.g., DPReview, Ken Rockwell, Lensrentals).
* Look at Sample Images: Search for sample images taken with the lens you are considering to get a sense of its image quality and bokeh.
* Rent (If Possible): If you can, rent the lens before you buy it to see if it meets your needs and shooting style. Lensrentals.com and BorrowLenses.com are good options.
