Thanks for the quick feedback. Very helpful indeed.

I’m using the new d5 mkiii so thought I had best compliment the camera with a good lens too. As for the mixed review – I meant that it seemed to summarise the review by saying this is a great lens if you want the range and simplicity of one lens suits most of your requirements…. BUT if you don’t mind the hassle of transporting more kit around with you, then look at a combination of lenses.

It does seem that 70-200 f2.8 II is the favourite around and the added bonus of being able to use an extender as well is an added bonus. BUT…. That’s a lot of cash considering the 1.4 extender and 70-200 still doesn’t reach the range of the 300.

I’d actually not thought about taking the leap to the 100-400 lens so what you say is really interesting and now adds more comparisons to the mix…. Back to the drawing board
