Mis-understood...
The mention of Zeiss Luminar is to point out these have become rare, sought after by collectors and perform not better than a reverse mounted enlarger lens.
Zeiss Luminar's are a tessar design optimized a specific magnification range for each focal length of Luminar.
My answer to this question had it's reply.. read the post..
*The common modern plasmant are good enough for close up in this range, they do meet the requirements of most users. Even an modern symmetrical Bigon type wide angle lens works for reproduction ratios in this range with surprising good results.
*If better performance is desired, use an APO process lens, enlarging lens or Macro specific lens (most expensive option).
*Remember to factor in bellows factor due to the reproduction ratio.
*Stopping down past f22 - f32 is going to reduce resolution due to diffraction while trading off for DOF (apparent sharpness).
