ePhotozine reviewed the Irix 150mm f/2.8 Macro 1:1 Dragonfly, a specialised lens for macro photography.

From their conclusion:

There is no doubt that there will be many photographers who will be delighted by the arrival of the Irix 150mm f/2.8 Macro lens. The greater reach of 150mm will be welcomed, and indeed is highly sought after already as photographers search for legendary long macro lenses from the days of film.

Manual focus can often be the method of choice for macro work, depending upon the techniques needed, but at least can be regarded as a little impediment. This is an excellent addition to the options available, especially perhaps for Pentax users who have had no option at all before this.

A specialised lens to some degree, but one that can be Highly Recommended.

Among other things they praise the Irix 150mm f/2.8 Macro 1:1 Dragonfly for the excellent sharpness, very well controlled CA, no distortion, no flare, weather sealed, and the bokeh.
