I wanted to test this again and now I am sure I finally found a way to scan 35mm slides that fits my needs. I have hundreds but only want to scan about 5% of them.
If you have a Nikon DSLR and a 55mm 2.8 AIS or 60mm macro you might be interested in my results and setup.
I bought some professional train slides on eBay and did touch up the results in PSCC.
