As much as I love my X100 series cameras for my everyday street work, there are occasions when I need/want to use a different focal length for a specific purpose. And 95% of the time it is to use a wider lens than what my X100 can give me. So far that meant that I would put the excellent Fuji XF 14mm f/2.8 on my X-Pro 1. It is a fantastic lens and works great for street photography, especially when using zone focusing. But if there is one thing that I would like to change about this lens, it would be to use it at faster apertures. The XF 16mm f/1.4 has a classic 24mm field of view in full frame terms compared to the equivalent 21mm of the XF 14mm lens. In real world numbers that will reduce the field of view from 90° (XF 14mm) to 83° (XF 16mm). That is not a whole lot but may be something landscape and architecture photographers may need to consider. While the field of view might not be much different the XF 16mm is a whole two f-stops faster! So who needs that on a wide angle lens? I do. In very low light situations photographers using this lens will be able to either shoot at a much lower ISO or keep the shutter speed short so they can safely hand hold or freeze the action in a shot. Let’s say you are in a situation where you shoot the XF 14mm at f/2.8 and 1/60s at ISO 6400. With the XF 16mm you now you have either the choice to shoot at f/1.4, 1/250s and ISO 6400 to freeze action or f/1.4, 1/60 at ISO 1600 at lower ISO while maintaining the same brightness in your image……..
