Minolta DiMAGE Scan Elite 5400 Scanner Lens
Mitutoyo M Plan Apo 5X 0.14 objective @ 3x

The biggest surprise was the performance of the Minolta Elite 5400 lens. The Qioptiq and Mitutoyo come out on top but the Minolta is surprisingly close to the M Plan. You can see all the details here: https://www.closeuphotography.com/3x-lens-test
