Factors to Consider When Choosing:
* apertura (f-stop): A wider aperture (e.g., f/1.2, f/1.4, f/1.8) allows more light in, which is beneficial in low-light situations. It also creates a shallower depth of field, resulting in a blurred background (bokeh) that isolates the subject. Lower f-numbers (f/1.2, f/1.4) are generally better for portrait work as they create more separation.
* Numpness: Mentre la nitidezza è importante, non dovrebbe essere l'unico fattore. Many modern lenses are very sharp, but a lens with pleasing rendering and bokeh is often more desirable for portraits. A slightly "softer" lens can sometimes be more flattering.
* Bokeh: Bokeh refers to the quality of the out-of-focus areas in an image. Look for lenses that produce smooth, creamy bokeh with minimal distracting artifacts (like onion rings or harsh edges).
* Velocità e precisione dell'autofocus: Fast and accurate autofocus is crucial for capturing sharp portraits, especially when photographing moving subjects.
* Qualità costruttiva: A well-built lens will be more durable and withstand more wear and tear. Weather-sealing is a plus if you shoot outdoors in challenging conditions.
* dimensione e peso: Consider the size and weight of the lens, especially if you plan to carry it around for extended periods.
* Budget: Set a budget and find the best lens that fits within your price range.
* Mount: The lens must be compatible with your camera's lens mount (e.g., Canon EF, Canon RF, Nikon F, Nikon Z, Sony E, L-mount).
