Just a comment which I hope will be taken in a positive vein. A portrait photographer needs a widely variable light source if DOF is to be effectively controlled with any one lens. If you are shooting candid portraite/available light portraits, you can change lenses when you need more aperture or increase your ISO. In a portrait studio with good lighting, you normally do not need to change ISO because good lighting is easily varied by four or more f-stops. The bottom line is that the PL 45mm DG is a good lens for portraiture if your available light falls within an optimum intensity range for this lens to work the way you want it to work. Because post-1870 designed lenses typically eliminate barrel distortion, it is no longer necessary to take portraits with lenses falling in the focal length range of 84mm to 150mm. Frankly, I often used the newer Nikon 24-70mm zoom lens for portraiture and achieved suberb results. Finally, some folks care and do not want a photographer in their face when their portrait is being taken. With these folks, a 40mm to 60 mm lens(35mm equivalent) is bound to rattle the subject whereas an 85mm or longer lens may not. Then again, one has to have sufficient room to use a longer focal length and space can be a problem these days. It all comes down to personal preference, in my opinion.
