For anyone wondering as I could not find anyone who had used this lens for film digitising.
Without an extension tube the lens provides excellent detail, almost filling the height of the sensor with around 10-15% of the sensor unused. With an 18mm extension tube, 645, 6x6 and 6x7 all fit the sensor fully.
Attached is a test target of the 110 f5.6 + 18mm extension tube. I can not see any optical shortcomings with this setup.
A GFX should match 645 perfectly, they both have a 3x4 aspect ratio - as does any micro four thirds camera.
I am referring to the minimum focus distance of the lens
Yes, sure, and there is no contradiction. At MFD, the lens has a max. magnification of 0.5, which means that an object of 87.6 x 65.8 mm should fill the frame. There is some slack in these figures, technical data can be nominal at times, but let’s take them at face value for now.
The usual 120 film formats have the following dimensions which make them fit the GFX combo without having to cut parts of the negative … which means that some sensor pixels aren’t used for the actual photo, but for its surroundings.
With MCEX 18G, magnification goes to 0.7 and object size to 62.6 x 47 mm which fits 645 format negatives at MFD. Other formats can be made to fit.
These things considered, you got yourself some nice gear and you could - if necessary - add some shift to eliminate reflections. With lens data printed around the front tube, reflections should be minimal though.

I’m not sure that I’ve ever seen anyone post the results from the 120 target and I don’t have one so it’s hard to interpret it. Looks like Group 0 Element 3 in those two corners but it’s a little hard to see, is it the same or better in the centre? If you already have one of those lenses, as you do, then it looks like a good performer. It’s designed to go down to 0.5x without extension tubes and since it’s a shift lens you are using the centre of a larger image circle.
Vlad’s 120 target equates to 43 lp/mm for Group 0 Element 6.
I am really just trying to find the best possible lens for this application under ~$3000 AUD. I work at a camera shop and have the opportunity to buy this TS110 for about half the retail price so am considering it. I am mainly buying time until I inevitably go down the route of a Schneider duplication lens as the 90mm f/4.5 Digitar seems to be the best option for my needs, though I have not seen test targets of its performance at the distances I need.
Right, I don’t know about Australian prices but even at half price it seems a lot if you don’t want to use it as an architectural lens. I don’t have a GFX but you’ll know all the possible contenders, which I suppose will include the Pentax 120mm Macro and the 75mm or even 120 mm Apo-Rodagons and Macro-Symmars. That 90mm Apo-Digitar does seem like a good bet but if your shop has an 80mm or 100mm Componon-S lying around you might try that to compare with the TS110, but then of course you need suitable bellows or a tube setup.
have spent months basically waiting for someone to tell me BUY THIS LENS! but have not been able to find any definitive answer as to which of the Schneider lenses will best suit my needs. I only lean towards the 90mm as I know a few people use that with Fotocare’s setup. My use case is 35mm, 6x6/6x7 and 645. Open to two lenses.
I am skeptical of the pentax or mamiya lens options being up to scratch compared to a duplication lens. I’m sure theyd be excellent but my use case is very large prints over 1m so every detail will be important.
Have a look at novoflex.de
All things considered, they offer a good mix of gear (including the Schneider Kreuznach lens) that, in combination with a sturdy rig, should provide what you need - including motor driven/geared rails as well as geared heads.
The money and time I spent for trial setups could probably pay for a complete setup by now. 
Ha, I don’t think anyone would be bold enough to say that, there’s a lot of money involved for a start. It may well be that you need a separate lens for 35mm at 1.2x though. With a full frame digital camera copying 35mm film it’s possible to get a very good idea by consensus, and because enough people have uploaded results with Vlad’s 35mm Test Target. So it’s hard to go wrong with the 70mm & 105mm Sigma ART, or the two 75mm Apo-Rodagons, 2x & 1x. The 2x is seemed to be very, very good for 35mm, right up there, until someone (Peter Orth) posted a comparison between his 2x & 1x and the latter was clearly superior, but needs to be used at or very close to 1:1. These and other examples are on the FB forum “Digitizing film with a digital camera”. Possibly the best I’ve seen for the 35mm Test Target is also on that forum posted by Jan Pražák, that’s with a 50MP Hasselblad back and an 80mm f5.6 Makro Symmar. He also shows the results from the 120 target with that lens. Probably worth a look, source files can be downloaded as they can with Peter Orth.
