I have finally saved enough for either of these 2 lenses and now I am completely undecided
I would like to go with the 600 as have tried it a few weeks back and it can be handheld but i would need to be in one spot and not mobile as I usually am
The 500 would be easier to hike with and to travel with as well but would sacrifice the 100mm of reach (more with the TC)
My D800e does allow me to crop nicely but if I am going to spend the cash i dont want to regret not going for the bigger lens and get the frame filling images I would like
Any help taking the decision would be appreciated
Thanks
Shane
