USD-wise...how much are we talking about?
Of course, I only bought a couple of these things specifically for scanning film; in fact, only one thing ... the Essential Film Holder ... where the rest of the equipment is part of my usual photographic/computing kit. But if you want to tally up replicating this exact setup:
iPad Pro 11" running Leica FOTOs app :: 2018 model with 1T storage, $1800
Novoflex Magic copy stand :: $319
Hakon flat-panel light box :: Had it too long to remember, but better ones now $60
Essential Film Holder with 35mm standard frame fitted :: $150 with the masks I have
Novoflex focusing rail :: $279 (could do without this entirely, but it's convenient)
Leitz Macro-Elmarit-R 60mm f/2.8 + Macro-Adapter-R :: about $650 last I looked
Leica R-Adapter-M :: $455
Leica M10 Monochrom + Visoflex 020 :: call it about $8000
Totals up to about $11,700 roughly. BUT ..
Remember that the iPad Pro I've had since 2018 and use for a billion other things, the copy stand and focusing rail I bought before that, the macro lens and tube I bought when R system kit went for peanuts (about 2012), the R-Adapter-M was about $250 used, and I bought the M10-M to do a lot more than just negative copying.
Presuming you've got some kind of camera that is usable (nearly any which can take a macro lens) you need:
- an appropriate lens (good close up lenses or extension tubes are both quite usable, as well as a good used macro lens) ... about $90 for my Micro-Nikkor 55mm f/3.5 + M-tube
- a decent copy stand ... figure $200-300 for a good one
- a film holder ... the EFH is very good an reasonably priced $150
- flat panel light box ... $60-$70
So call this kind of setup about $500 over and above your basic decent camera kit, which is less expensive than a good film scanner (my Nikon CoolScan V ED that I bought a decade ago was over $750 used then...).
