The range of third-party lenses for the Fuji X system is rapidly expanding and here we have a new, compact Samyang AF 12mm f/2 lens that broadens the possibilities. Coupled with the 26MP Fujifilm X-S10 body, this gives us a “35mm equivalent” field of view of around 18mm, a definitely ultra-wide lens. At f/2 it is also fast, which in itself opens up the possibilities of low light use and more selective focusing because of the reduced depth of field. So now let's get out there, shoot some pictures and see how the new lens handles and performs.

One image can change us.

A picture, a moment can change the way we feel. Change how we see ourselves. Change our understanding and change the rules. Provoke and change history.

Samyang AF 12mm f/2 X Handling and Features

The lens is small and light, weighing in at just 213g without caps or hood. Add the hood and it tips the scales at 225g. It balances very nicely on the Fujifilm X-S10 and sits squarely and with stability on a flat surface, so it could be placed, for example, on a table or flat wall top for shake-free long exposures.

Starting our tour of the lens at the front, the provided petal lens hood clips securely into place. There is no tendency for this to become dislodged during use. Within the bayonet fit for the hood is a conventional 62mm filter thread. Behind this, and visible when the lens is viewed from the front, is the “hidden red ring” which is mentioned several times in the Samyang literature and appears to be a design flourish. On that basis, it is aesthetically pleasing.

The wide manual focusing ring affords an excellent grip, but manual focus is not the easiest way to use this ultra-wide lens. There is a useful manual focus scale in the viewfinder that becomes activated in MF mode, but the overall need for MF is not the forte of this particular optic. The AF system, driven by a linear STM motor, is fast, very quiet and very accurate, far better than we could achieve by eye. It is possible that the MF setting could be used to set a snapshot focus point for street photography, so having the option is good.

Focusing is down to 0.2 m, or 0.66 feet, for a maximum magnification of 0.09x. This is usefully close, but not in the realm of macro photography.

The lens is weather-sealed, protecting against moisture and raindrops, and a rear protective glass adds to the level of sealing. The bayonet mount is metal, is well made and clicks securely into place without even a hint of rotational play.

Optical construction is 12 elements in 10 groups, including 1 Hybrid Aspherical, 1 Aspherical and 3 ED (Extra-Low Dispersion). The diaphragm comprises 7 blades. Flare resistance is enhanced by the use of Samyang's well-proven UMC multi-layer coating techniques.

There is no shake reduction, just as there are no additional controls on the lens. Everything is handled by the camera body. As such, the handling of the lens is very straightforward - focus, compose and shoot. The lens becomes an extension of the eye and there is little else to distract from that creative process. This could well, therefore, appeal to street photographers looking to get right into the action, even becoming a part of the ebb and flow as opposed to being a simple viewer from a distance.

Other applications include interiors, food, lifestyle, astrophotography, nature and architecture. The taste for wider angle images has been steadily growing wider and wider over the years, so whereas once a 35mm (full-frame) lens would have been considered wide and a 28mm ultra-wide, this perception has meant that this 12mm (18mm full-frame) has now entered the mainstream and at a realistic price level too.
