I'm still on the fence with a telephoto for my D800 for upcoming personal trips. I want to avoid a large heavy lens for summer travel but do want something in my bag in case I see that one great shot that requires a longer lens. My thoughts are:
Nikon 105 Micro - good quality, fair price, lightweight, but kind of short at 105mm
Nikon 70-200 f2.8 VR2 - good quality, heavy and expensive
Nikon 70-200 f4 - good quality, smaller than the 2.8 but overpriced I think
Zeiss 135 f2 - superb but expensive and no AF (I will have one eventually if I stick with Nikon)
Sigma 150 2.8 Macro - small, fair price but is it any good?
