Godfrey, Igor & Mark, Thanks for your comments. In my case, I pretty much know I'm looking for the impossible; a much more rapid way to transfer slides to digital images. I know that the Epson I use does a great job, but it's a slow process, and I have thousands and thousands still to do. As I've found from the Epson, larger dpi scans above 4000 tend to show up imperfections in - or rather on - slides, such as really tiny specs of dust which even with decent cleaning and dust reduction still show, giving more work in Lightroom at a later date. A K3 sensor sized image is really all I need, but it is keeping the quality that the scanner provides that is the issue. Some of these scans from slides I enlarge to A3 prints after work to correct all the howling errors, such as 100% level horizons etc have been adjusted all these years on. The fact I can restore or improve pictures taken in the 1970s still amazes me, but now I want it faster. Some people, you just can't please.
