Wide and Fast - Fujifilm 16 f:1.4
It follows precisely the style elements of Fujifilm X lenses - metal construction, smooth focusing ring, precise click stops for the aperture, and fast focusing.
It has the addition facility - shared with the 14mm and 23mm lenses -of snapping the focus ring out of automatic focus into a mechanical manual focus. Wonderful for studio shooting, particularly if you have activated the focus peaking on your X-series camera and can watch the plane of focus "walk"over your subjects.
The real forté of this lens is the wide aperture - f:1.4 - which means it is perfect for interiors. The real estate photographer using the Fujfilm X system could make this lens their primary optic - it will render straight lines straight and give the breadth of vision that sells houses - even pokey little ones...
I can also see it capturing the magnificence of a cathedral interior during a wedding - or trailing out to all the seaside landscape points that fascinate Western Australians.
