Well it was a good try. Back to the drawing board. Does tesi need a longer lens or a longer tube, too late for me to figure. I figured that a FD 50mm macro full frame lens circa1973 with FD 25-U tube gave 1to 1 nicely.....and even allows cropping and movement in two planes with the auto bellows nifty copier gadget....that was a coup d'etat to find the works in A-1 shape after a long search. Velbon makes a bellow, a so so bellows. RRS is unaffordable but swell... Getting a good rail system or a bellow with rail is a job to find- read will take patience, sorry- but they are out there. I am sorry this expenditure did not pan out. Now what? I await other ideas. I got my slides fine res with JPEGs using 12 megs, it all you need unless you have great archival ambition, beyond just preservation. I wonder what the pro copy outfits use, just for fun....I will follow this with interest. Kind of a production operation, and can be boring. Idea: Buy a Lumix G-something with a fold out screen Life will be easier, and set WB by eye- less fuss later. I wish you well, sir..
The ideal lens to use with the Nikon ES-1 copy attachment is the old 4/3 35mm macro lens, needs an adapter of course to fit to M4/3 mount.
The ES-1 screws straight onto the lens with matching 52mm thread, set lens at around 1:2 and everything works nicely.
The only hint when using a regular Oly M4/3 Pen or OM-D body is to turn off the "reset to infinity at turn off" as it moves the whole ES-1 quite a distance with that 35mm lens when going back to infinity focus, may stress the focus motor if done too often, use manual focus anyway to stop any AF seeking problems.
As mentioned, I wasn't happy with 12MP slide copies, but 16MP does it nicely, there's no more that can be sucked from the slide as 16MP is better than any 35mm slide film.
Some have used setups as simple as a macro lens and a few hours work with timber scraps and a bit of diffusing plastic behind the slide/film. True macro lenses are always recommended due to their better flat focus field ability.
Here's one slide from a temple in Kathmandu....

And now a 100% crop of a bit.......

That was done with an E-PL5 and the 35mm lens, but now I use the 60mm macro lens. Using my dedicated film scanner at 4000 dpi maybe gets a bit more pixel peeping detail clarity (at a terribly slow scan speed penalty). Any normal view or print would never see the difference. I also checked the slide with my old lab microscope and could see no more real detail in the slide than you can see here.
All good fun but the 16MP sensor is all that is needed for really fast slide copies.
Note to self: Must extract the digit and copy the rest of the the zillions of slides cluttering the house.
