Sony G Master 85mm - Would you?

Looking at my "lens path" which is a mythical path towards the ideal set of camera lenses that i want / need (want) and I see it has changed very much since my more serious involvement in photography. 



I was once all about the Canon 16-35, 24-70 and 70-200 and those three served me perfectly. I had the trilogy and I had a couple of extras, the f/1.8 Canon 85mm as well as the 100mm f/2.8 Macro, also Canon, then along came Sigma with their Art series and I found myself buying the 35mm f/1.4 (Brilliant lens!) for my brother's wedding, and then by some luck, I ended up with the 50mm f/1.4 - both stunning lenses. 

Then something happened that also happened to a lot of others - I switched out to Sony. 

It started with the Sony a7, that's gone now and I have an a7Mk2 and an a7RMk2, both stunning cameras, but this has actually led me to a different style of shooting - I find myself more measured and sticking with primes almost 100% of the time... I use the Sony 55mm f/1.8 a lot, I have a 35mm f/1.4 Distagon which is pretty much always on my camera... I've kept the 16-35 and the 100mm Canon lenses and will do so for a good while - I use them with a Metabones or Vizelux adaptor. 

BUT I've lost (read: sold) my 85mm Canon and I'm in the market for a great portrait lens, something a little longer. The G Master series is getting some amazing write ups and comment online, but it's a pretty expensive little beast! That said, I'm almost toying with selling the a7Mk2 and getting the 85mm... Not sure, torn, what would you do? I use the a7Mk2 infrequently, it's my spare - so to speak - but then, as I shoot for money so infrequently, I'm not sure I need it. The two body thing is a hangover from shooting music - one body with long, one body with wide. 

Time will tell! <--- That's the lens I'm thinking of getting.
