Which lenses should I choose?

[Beaux Reflets]

Thanks OB and Stephen, very helpful.

I have to admit that when using my S8000fd I quite often zoom out quite a bit to achieve the balance in composition I want within a landscape shot. So I am now thinking of just getting the one 50-140 lens to use as my prime and working out if there are any personal short falls before shelling out more dosh. 

Thank you all for your input 

The hesitation I have is buying into a new system then lens choice just complicates it even more. That said Fuji have said themselves that they were still in development with the early lenses and they are slowing down now with the speed they put out new bodies / lenses. The newer ones like the 50-140 very fast to focus. I used a 56mm 1.2 on an XT1 and the quality was excellent, although I read one review saying even this one hunts for focus in low light / kids movements. I`m still so unsure of the need for me to invest as I love my dslr so much.

I'm spoiling myself in away Paul, purchasing because of the OIS aspect and the advances made in sensor technology in more recent years
