Factors to Consider When Choosing:
* Budget: This is often the biggest factor. Start with an affordable f/1.8 lens and upgrade later if needed.
* Aperture: A wider aperture (lower f-number, like f/1.2 or f/1.4) allows for shallower depth of field (more background blur or "bokeh"), better low-light performance, and creative control. However, wider aperture lenses are generally more expensive.
* Autofocus Performance: Consider the speed and accuracy of the autofocus system, especially if you'll be photographing moving subjects.
* Sharpness: While all lenses are sharp enough for most uses, some offer greater sharpness and detail than others. Look at MTF charts and read reviews to compare sharpness.
* Bokeh Quality: The quality of the background blur is important for portraits. Look for lenses with smooth, creamy bokeh.
* Build Quality: If you'll be using the lens heavily, consider a lens with a robust build.
* Size and Weight: If you want a compact and lightweight lens, the f/1.8 options are a good choice.
* Manual Focus: Do you prefer manual focus? This opens your options to a wider range of lens.
