you could just tweak the zoom level a bit, make it like 1.59 or 1.40 instead of 1.5 (which is standard) and the same for the second zoom level, which is 5x i believe, in stock.
this is the obs. periscope's zoom levels, the entries in between the prior and next camuserdata are for that camera, and the UZO has its own camuserdata..
hope this helps you out
