No. Sony don’t make drivers for Sailfish so Jolla have to use a compatibility layer called libhybris which I presume calls the Sony camera Android drivers. Jolla also replicate Androids’ API so you have a Jolla app calling Jolla’s Camera API 1, which calls libhybris.
Anyone - let me know if I got eg the libhybris bit wrong. 
I wrote a couple of informative comments here and here.
An aquarium is pretty niche – I would give that 50/50 to work here except on manual or the other lenses.
