10. Focusing

The Samyang is a manual device so you have to set the sharpness on your own. As we’ve already mentioned in the case of the tested lens it would be difficult to do it with a great precision because of slacks of the manual focus ring. It is a serious drawback because such a ring is a crucial element in every manual lens.

As a consolation you can say that its short focal length and the wide angle of view guarantee a quite significant depth of field. How significant it can be assessed by looking at the depth of field scale which is on the lens.

For example in the case of f/2.0 aperture setting the focus at 3 meters will provide you sharp images from 2.3 to 4.35 meters. When you apply f/5.6 aperture the situation becomes more comfortable because the focus ring set at 3.5 meters gives you the image sharp from 1.7 meters to infinity.
