Key Considerations for Portraits:
* Aperture: A wider aperture (lower f-number like f/1.2, f/1.4, f/1.8) is important for creating shallow depth of field and blurring the background (bokeh), which isolates your subject.
* Sharpness: While sharpness is desirable, it shouldn't be the *only* factor. A lens that is *too* sharp can accentuate skin imperfections. Slightly softer lenses can be more flattering for portraits.
* Bokeh: The quality of the out-of-focus areas (bokeh) is crucial. Look for lenses that produce smooth, creamy bokeh without harsh edges or distracting shapes.
* Autofocus: Fast and accurate autofocus is essential, especially when shooting portraits with a shallow depth of field.
* Build Quality: A well-built lens will last longer and withstand more wear and tear. Weather-sealing is a bonus, especially if you shoot outdoors in challenging conditions.
* Focal Length 'Feel': While 50mm is a classic focal length, it can feel a bit tight on APS-C sensor cameras (equivalent to 75mm-80mm). In that case, you may consider something like a 35mm.
