For people who do portait work 1,4 may be handy I dont do that so I don't need one that fast, to be honest, another lens I am thinking of is a sigma 150-600 but That's more for birding or sport and such which I don't do a lot of either so I probably do not need that either.

So as you can guess I am not sure what I will get next, I do have some money coming in from pront sales soon and then I will have to decide, at the moment what is at the top of my list is one of the following

Two new filters for longer exposures I have a ND grad and a 10 Stop which I have been using a lot recently, having 1 3 and 6 Stop ND I may make use of
and the 50MM 1.8 sony which is only 300

The other option I am considering which would be good for city and landscapes to have a wider lens is the sony 12-24 but thats $1700 but I don't think I will have the funds for that
