Macro lenses are optimized for the close focus or at least roughly optimized over the whole focus ranges. Irix is not.
Thanks. A very useful review.
I looked this lens up 3 years ago, on a very well-known lens review site. It was a not a glowing report but it missed most of the faults.
It did recommend the Printing-Nikkor 150mm which I have but it is very heavy and difficult to use; My calibrations:
Extension mm Working Distance (No hood) mm FOV mm Mag
145, 390, 36, x0.5
225, 210, 17, x1
340, 155, 10, x1.7
385, 150, 8, x2
(The forum won't accept my spaced formatting).
