With a big pile of macro lenses at my disposal this weekend was my last chance to run a LoCA test before the 105 and 200 have to go back to Nikon. To keep things simple I did not include any Canon or Sony lenses this time but I plan on adding the Sony 90mm and a few Canon macro lenses at a later date.

Lenses tested:
Sigma 50mm F2.8 EX DG Macro
Sigma 70mm F2.8 EX DG Macro
Rodenstock 75mm f/4 APO-Rodagon D
Schneider Macro Varon 85mm f/4.5
Nikon Scanner Nikkor ED 100mm
Sigma 105mm f/2.8 EX OS Macro
Nikon AF-S VR Micro-NIKKOR 105mm f/2.8G IF-ED
Voigtlander 125mm f/2.5 APO-Lanthar
Sigma 150mm f/2.8 EX OS APO Macro
Sigma 180mm f/2.8 APO EX OS Macro
Sigma 180mm f/3.5 APO EX Macro
Nikon AF Micro-NIKKOR 200mm f/4D IF-ED Lens
Test procedure:
Nikon D810 clamped on to a PRC-3 carrier on a PRL-12 rail with the target at 30 degrees on a tilt head lit by a single SB-R200 wireless flash. Camera and lens were moved on the rail to focus and to accommodate the changes in focal length. The flash and target never moved during the test. All files shot in RAW and converted in ACR with all lens correction off.

Laser printed target shot at 1X as above and cropped down to 800 x 900 px for each. The images shown in this post are 1000px but you really need to see these at full size to appreciate the differences.
For larger full size 2400px comparison images you can see the test on my site:

And click on each image to open in a lightbox viewer full size. If you have any trouble seeing the full size images just PM me and I can send you a link. My website sometimes sends smaller size images depending on what resolution you are browsing on at the time.
