The Samyang 1.4/21 is a manual lens, without any autofocus mechanism. Usually producers of such devices apply a depth of field scale on the body in order to make your task easier. This time Samyang decided not to do it and it’s a pity, especially that the lens doesn’t feature any contacts and mirrorless cameras such as e.g. the Fujifilm X-E1, used in our test, don’t ‘see’ it and can’t communicate with it. The electronic distance scale, displayed by the camera, remains inactive.

The focus peaking function might undoubtedly help with focusing; although the lens provides a wide angle of view its aperture means there are situations when the depth of field is not large enough and you must really apply yourself to setting the focus. Still from f/2.8 aperture upwards the depth becomes so large that in many situations it is enough you know the hyperfocal distance and you’ll be able to shoot a decent photo without any problems. For example by f/2.8 it’s enough you set the focus at less than 8 meters in order to enjoy sharp images from less than 4 meters to infinity.
