Just posted a test of a PrimeFilm XE scanner lens, one of Pacific Image Electronics advertised 10,000 dpi scanner line up.
This test is really important for a couple of reasons.
-Finally I get to see what an advertised 10,000 dpi scanner lens is really like.
-The results from the 3100 dpi Nikon LS-3510AF lens blew me away!
-The Pacific Image 10,000 dpi lenses turn out to be very similar to their 3,000 dpi lenses
-This test was completed in the shortest time ever, 2 days from opening the box to published.

1.1X SCANNER LENS TEST: 10,000 DPI LENS VS 3100 DPI LENS
PF10K 42mm f/6 Set-up: Barrel paint mark towards subject
Nikon 51mm f/3.6: Barrel paint mark towards subject

The sharpest frame was then selected out of a stack of images made in 4 micron steps. Separate images were selected for center, edge, and corner if needed. Each image was processed in PS CC with identical settings with all noise reduction and lens correction turned off, all settings were zeroed out (true zero) and the same settings were used for all of the images. All of the images shown here are single files. The PF10K lens used different frames for the crop images, the Nikon was just a single frame for all the crop areas!

Two things to take away from this test?
The Pacific Image Electronics PrimeFilm XE scanner lens is not a 10,000 dpi lens.
The XE lens is not bad just not anywhere near a high-end scanner lens.
Surprise, the Nikon LS-3510 is shockingly good!
Questions, comments?
