10. Focusing

As mentioned in chapter 3, the focusing ring is properly damped and moves smoothly, offering you a working range of 270 degrees. However, if you leave out the macro range and close plan up to three meters, you get just 10 degrees of turning for all the rest. Not much.

Irix 150 mm f/2.8 MACRO 1:1 Dragonfly - Focusing

A precise focusing in a range not only from 3 meters but even from 1 meter to infinity, with the working range amounting to about 45 degrees, is very difficult. Depth of field by f/2.8 and the 150 mm focal length is really shallow so it cost you a lot of effort to focus the lens on the object you want to be sharp. That fact really questions the usefulness of this instrument when it comes to, for example, portrait photography. I know perfectly well that it was designed to cover the macro range but I also am aware that many macro lenses are used for portraits and with very good results.
