POLAROID SPRINTSCAN 4000 SCANNER LENS TEST vs Scanner-Nikkor ED at 1.35x:
https://www.closeuphotography.com/polar ... -lens-test

The test lens was a loaner, so thank you Typestar for making the test possible.
The Ploaroid SprintScan lens is a 43mmm f/5.6 and is an apochromat.
The slow aperture limited the sharpness, its a shame since the lens shows zero CAs. It was a little unfair comparing it to the two stop + faster Scanner-Nikkor lens, f/5.6 vs f/2.6. Both made some nice images, and the Polaroid was very consistent from center to corner.

Scanner Nikkor

The differences between the lenses is pretty easy to see. The Polaroid isn't a bad lens, its just doesn't have the resolution of the Scanner-Nikkor and I'm sure it will make some great macro photos thanks to the great CA correction.
Click on the link to the full test if you would like to see the corner crops, they are very close for both lenses, the Polaroid corner crops are just about identical to the center.

Questions, comments are welcome.
