For general rating criteria, please see the Lens Survey Page . I tend to favour long lenses for my line of LF photography. The colour aberrations give lower image contrast besides reducing sharpness. I found its colour rendition a little on the cold side for my taste, and there is a greyish colour cast to the image as well.
Colour rendition is excellent and image contrast is fairly high, too.
However, I regularly use this lens on my 6x9 cameras for general-purpose photography and optical results still are excellent. Used this way, the image circle is entirely adequate for the 6x9 format, but movements must be done with some care. Flare and ghosting are seldom a problem with the 120 AM as long as a lens hood is attached, the HN-3 for 35mm Nikkors being entirely suitable. Excellent macro shots then are possible without excessive bellows draw. The 150 is quite resistant to ghosts and flare and its colour rendition is snappy to match its high optical quality.
