150-600 Tamron or Sigma?

[PaulWog]

Since we're talking about weight: i just looked into the weight of the nikon on amazon and here are the results:

Sigma (C) Item Weight 4.25 pounds
Sigma (S) Item Weight 6.31 pounds
Nikon 200-500 Weight 7.28 pounds<----heavyweight champion! Goodness, what is in this lens that its so much heavier?

edit: BH is saying it's 4.6 pounds, and Jared Polin says 5.1 lbs.

Nikon's website says approximately 5lbs: Nikon Imaging Products AF-S NIKKOR 200-500mm f 5.6E ED VR

I'd take nikon's specs over the others. 5 pounds fits right between the (C) & the (S) and follows the suggested price.
