Fuji 56mm f1.2
The 56mm f1.2 is one of Fuji's newest and most impressive prime lenses. The lens offers an 85mm full frame equivalent field of view making it an excellent choice for a portrait lens. It's amazingly sharp even when being shot shot wide open.
Shooting full length portraits you'll need some space between yourself and subject. Due to the large aperture the lens excels in low light situations. The 56mm f1.2 combined with the 23mm f1.4 make an excellent combination allowing for broad coverage suitable for most travel/portrait situations.
