The XF 23mm f/1.4 R takes some points here, being among the older – but not oldest – Fujinon lenses (from 2014), one of the lenses with the widest aperture, of f/1.4, and being among the bigger and more heavy prime lenses. But being big and heavy for a Fuji lens, is rather relative compared to lenses of other brands. And this lens creates magic. The 23mm focal length, which equals 35mm on a full frame sensor or a 63.4 degrees angle of view, is great for a lot of casual shooting, street photography, and even some kinds of portrait photography. However, the very wide aperture and amazing image quality, is what makes this lens magical. It is a lens made for the creatives, allowing you to express whichever thought comes to mind.
