I was quite surprised how sharp those came out since i expected them to be more blurry. OIS helped a lot here i think. Originals can be found here

I'm still not sure which are best settings for night shots. ISO-100 shot looks best overall maybe bit too dark. If you have time use lowest ISO possible and take multiple shots since it is very possible that photo come out blurry due longer shutter speed. Maybe ISO-400 and -2 step would be all rounder settings but still it all depens of scene you are shooting.
