This weekend I finished up a test with some interesting results, the top three or four finishers are all probably pretty much unknown to 95% of macro photographers out there so be sure to check it out. To read the full test click on the image above or use this link:

3.4x II Lens line up
Canon Macro Photo 35mm f/2.8 Lens
Canon MP-E 65mm 1-5x Macro Lens
Copal 35mm f4 E18C Printing Machine Lens
JML 21mm f/3.5 Lens
Noritsu 32mm f4 Printing Machine Lens
Schneider APO-Xenoplan 35mm f1.8 Industrial Lens
Schneider Componon 35mm f4 (at f/2.2) Industrial Lens
Schneider Xenon 35mm f/2 Industrial Lens
Tominon 35mm f/4.5 Copy Lens
Standout lenses are the Noritsu 32mm and Schneider Componon / Xenon 35s. The Componon was run at f/2.2, over a stop wider than in the first 3.4x test with much better results. The first 3.4x test had a slightly different lens line-up and a different target disk : https://www.closeuphotography.com/three-point-four-x-lens-test
