Lens Turbo II PK-NEX First Impression

I am still using my NEX F3 + Lens Turbo II and think that I can add a few lens to compatible / incompatible list.

Working:
K28/3.5 shift - very useful!
FA28-70/4 - it is a nice light setup
FA28-105/4-5.6 Powerzoom
A50/1.2
A24-50/4

Problematic:
K28/3.5 - cannot focus to infinity due to rear lens hitting the front element of LT II.
Sigma 24/2.8 Superwide II - this one is strange as it seems that the locking pin of the LT cannot fit into the corresponding recess of the lens.

For all the lenses that work, the center resolution is always very good - sharp and detailed. I cannot comment on the quality of the corners. I can only say that they are all acceptable. I do not think that any of them show very bad corners compared to the typical corners that I see on my APS-C bodies.
