Below is the index images. I tooks 16 shots of the same image using the 4 lenses. The first shot was the largest F stop for each lens, next 5.6, 8, and 11. I used an Elan IIE on a tripod with selftimer mirror lockup. The light did change a small amount from image to image as clouds drifted. Exposure was determined by the Elann IIE matrix metering. All of the images were scanned using a Minolta Dimage Dual at 2438dpi. The same brightness adjustment was applied to all images.

How do these images compare to what you would see in a print?
This is not a trivial question to answer, but 300dpi is generally considered the maximum resolution you will get out of conventional print. Based on that, that scans are a representation of the detail that can be seen on a good 8x10 print. However, if you are viewing the images on a typical monitor, your are viewing the images at about 72dpi. Consequently, the images on your computer screen are aproximately 30X enlargments of the negative.

Maybe you are thinking that this is all very interesting, but the reason the tests don't show much difference is that the scanner does not scan at a high enough resolution to pick up the differences. Well I was concerned about the same thing, so I decided to take a picture of the slides using a microscope and then scan those images.
