Anyone here who thinks it could make sense for someone who owns the Canon 17 TS-E and 24 TS-E to add also the Zeiss 21mm? If so, why? And by the way, does the Zeiss 21mm distortion rule out horizon shots over water?
No, it makes no sense at all. Nevertheless I've done exactly this about a year ago. But after buying the Zeiss and realizing that I very seldom pick up the 24 TS-E I sold it and later also the 17 TS-E.
I very often use the 21ZE for shots with the horizon over water and find the result perfectly acceptable.
From a rational point of view it will probably makes most sense for you to just keep and use your two TS-E lenses and don't get the 21ZE.
But I never regretted my irrational decision.
