Interesting, have been thinking the same albeit for use on the Fuji GFX...
TimoK, can you please elaborate on this statement " I have 24tseII and 1,4II which should be better than III with wide angles "? Why would that be the case?
Shiftworker, great t hear you have had success with this combo, can you possibly elaborate on your statement " greater shift range as the 1.4x applies to shift as well so the maximum shift you can get is nearly 17mm! "? If this is the case, what are you using this combination on, a view camera of some description?
Also, does anybody know when using this combination coupled with a "smart" adapter (either on a Sony or a GFX) whether you are still able to effectively control the aperture of the 24mm TS-E II?
Thanks in advance!
