Epson 4870 and Nikon LS 50 Chart

[Mike Engles]

Hello

Here is a comparison of a resolution chart.
Both at 4800 DPI, no cleaning or sharpening, just levels in Photoshop.

Hi Mike -

Thanks for posting the comparison. What material was used in the
construction of your chart? It almost appears as if it has paper-like
creases but I am guessing that can't be right since you used and LS 50.
Just curious.

Thanks,
Doug

Hello

The chart is a old Patterson lens testing chart.It is paper
I used it to check my lenses. This particular test was my medium format
Bronica ETRS 75 MM lens, I think.

I have several copies, so I chopped it up and put it in a 35mm slide
mount.
