I use a Sony a7r2 and M/LTM lenses in combination with a set of M mount Novoflex extension tubes I've had for a while.
It does the job for me - I like the flexibility over a scanner. Especially for rolls/frames that are awkward for whatever reason - overlapping frames or different sized formats - and for getting better output than my Pakon 35mm scanner especially from black and white film (not that I always want/need this.)
I use a little 35mm enlarger as a copy stand on top of light table and neg carrier from Durst M70, plus a cardboard tube between lens/negative to eliminate any flare (this makes a big difference in my setup)
I prefer the 'top down' approach myself, since I'm always skipping between sizes/formats and the 42MP sensor means I don't have to worry about framing, it only takes a moment to adjust up/down for focus.

One area I haven't got to is digitizing prints – anyone have any particular tips for that? Ideally I’d like to capture the print as a whole (ie; including border) to show that it is a print but flattening fiber prints, you know the drill. I get them nice and flat in my press after toning but then they go into portfolio books or paper boxes or get matted/framed once in a blue moon – it’d be nice to ‘scan’ them as a routine part of the process.
Perhaps I'd be better off making a matboard carrier for the print and front mounted flash?
