Here are the facts:
1) There are MK I and MKII shutters in existence.
2) MKII are on newly mounted third party X lenses, ie an Alpagon 70 HR
3) I was told I cannot remount 2019 vintage XT lenses to third party – helicoid and mount replacement – without a new shutter and sending in my old lens so P1 sends a new lens to the mounting company, ie Alpa for example – I was quoted around 6k for a transfer from XT to Alpa X many months ago (because I wanted tilt); quite surprised, I left it as it was the same almost than just keeping the XT lens and buying a second one – P1 likes to work with "trade-ins"; ofc it is not a good deal then. I bought the lens a second time.
4) The 32 XT tilt promo is a trade-in, not a factory upgrade
5) When putting the 70 HR and 70 XT upside down on a table, focused to infinity with the respective helicoid, I can clearly see that the XT X shutter is placed at a different height distance from the front lens element – it is pretty obvious, multiple mm (the distance between shutter and front element is not affected by focusing position on the helicoid) – it also implies the shutters internally are built differently;
6) When looking at them side-by-side it seems to the eye, but I would need to take them out to put them side-by-side on a table that the height of shutters is also a tiny bit different – no I cannot undo it from the XT lens as this lens is very well made with everything screwed together in a totally different way than non-XT lenses – remember, XT has an electrical information channel in the housing to transfer info through the mount to the shutter
7) I also reached out to P1 many months ago asking why one cannot transfer lenses and all I got was legalese saying effectively that the lenses work as promised for their intened use (ie for the XT system and were never marketed as being transferrable)
So the technical problem can relate to different measurements of the elements and / or problems arising from the information channel in the mount which makes it somehow incompatible and/ or, finally, slight modifications to the lens housing ex factory at Rodenstock from back in the early days when they commissioned the first set of lenses except the 40 and did some custom stuff to integrate the helicoid, wiring, gen I x shutter.
The existence of MK I and MKII, the lead time between the initial first gen set of lenses 23, 32, 50, 70, 90 and the 40 and the opening of the platform as well as the info that only full replacement would be possible when wanting to remount combined with the current promotio which is another trade-in make it pretty clear to me that there's something impeding upgradability to tilt.
I would appreciate a normal factory upgrade pathway – 2000-3000 for them to fix this so the lenses can be tilted would be fair IMHO.
I've asked for an explanation on what's happening and whether the 2019 lenses will ever be upgredeable – haven't heard back and probably never will because I think it is their strategy to just say 0 to minimize downside risk (backlash, claims for make-whole, etc.)
I hope there will be a scheme, but I am not certain this will happen given there's this 6500 promotion in the room. In a way, even if they now wanted to provide a special path financialy, you'll have the problem of people having now paid 6500 to do it – they'd not be amused.
At least one person in the poll will do it, it seems.
Find it weird that there's no official statement directed towards initial owners.
