Thanks for your comments everyone. Following on from Charle\'s Canon 35 TS test (love that building picture) have tested my Canon 24 TS-E L MkII on the Sony A7R_M
First impressions are that shifted to the extremes it is a tiny bit sharper in the corners than it used to be and behaves similarly to what I remember it on the Canon 5MkII. Had forgotten how average the lens is overall if not shifted. To demonstrate this the link below includes test pictures of all apertures with no movements applied and then two images with max shift applied at f8 and f11
Wow, does the TS-E 24 MkII really perform that poorly, or was it accidentally tilted? Without any foreground area on the right side, it\'s difficult to tell if it\'s massive field curvature, or a tilted lens. But that doesn\'t look like I\'d expect such a lens to perform. FWIW, I have the TS-E 17 and previous version of the 24. There has been some discussion about the 17 needing to be focused off-centre to optimize across the frame performance but your 24mm images look extreme...
No tilting unfortunately it does seem to have so quiet severe field curvature wide open and lacks in micro contrast compared to the Zeiss. However when shifted the issue seems to disappear and it works quiet well even at f8 which makes me think that it has been optimised to be used with movements and that it has to be focused carefully if using apertures wider than f5.6.
