10. Focusing

The manual focus ring is the biggest part of the lens. It is as wide as 36 mm and it increases its diameter after a while. Its narrower part features a distance scale, expressed in feet and meters, and the wider part is covered by fine ribbing, quite pleasing to the touch. The ring moves smoothly and is properly damped; its focus throw amounts to an angle of 300 degrees, a very high value. Still, you should mention the fact that the majority of its rage concerns the area close to the minimum distance. The range from 0.7 of a meter to infinity is included within an angle of 90 degrees, not such a big value anymore.

Venus Optics LAOWA Argus 25 mm f/0.95 MFT - Focusing

Also a big, clear DOF scale, with markings even by f/0.95, is supposed to make the focusing easier but it is the only help you get. As we've already mentioned, there are no contacts so a camera simply doesn't know that you move the focus ring and it cannot enlarge displayed images automatically in the viewfinder or in the screen. The lack of contacts is a drag and it really should be changed. Extreme parameters generate really shallow depth of field so every help in proper focusing would be more than welcome.
