I thought I would give an update to this saga.
I ended up going for the 200mm f/2.00 lens and I got it for a lower price than I had expected. Leaving some pennies in the bank. Now I just have to wait for Fedex to do their stuff (and the guy to leave it at the depot as promised today)

Sadly there seems to be a dearth of demo and hire functions in Finland compared to the UK and USA (lucky devils!).
Motivation was, after reviewing a lot of my past year's photographs, a lot of portraits and some internal shooting where the light was not so great (but the distance further than the 85mm f:1.8 I have. Plus in the winter I have some plans to photograph indoor sport. It was a tough call, but I tipped it to the 200. I will look at selling the Sigma 150-500 and some other bits and then to pick up a 300 or 400 f/2.8 when a great deal comes along and the pennies permit.
So thanks ! Come on Fedex! With my luck it will arrive on Friday in southern Finland and then they sit on it until Monday
