Apparently the digital blur was over used a bit too much. Slow pans, and otherwise, it wasn't as noticeable.
There was no digital blur added, the film was shot with a 270° shutter angle (1/64 of a second) to preserve just enough motion blur for the 24 fps version (films are typically shot with a 180° shutter angle). I've only seen the HFR version, but I can't think why motion blur would simulate focus issues, unless there was a focus issue with the projector (again, haven't seen it on imax yet).
It's also possible the iMax DMR blowup was to blame (most likely culprit, which is a shame, especially since the film was actually shot at 5k, but mastered at 2k).
I guess I don't understand your assertion that "Normally, things close should lose detail, while things far should stay in focus." Are you referring to positive space 3D elements, or just the style of the cinematography? I also ask because I may see it again in a different format (my local theater had 4 available, including HFR and iMax -- no iMax HFR though), before I decide if it's worth seeing the next 2 in HFR.
