Derrel, suggesting a SIGMA product?
Someone must be posting on his account for him... Either that, or the apocalypse is near.
One too many hits off the vaporizer this AM dude? Lemme' see....I own a Sigma 80-400 OS, a Sigma 18-125 DC, a Sigma 180mm f/3.5 EX HSM Macro, and a Sigma 100-300mm f/4 EX HSM zoom lens...three of their "best" lenses and one consumer-grade Sigma....
And yes, I was referring to used lenses. The Nikkor 500 is the manual focus (feather-touch, mid-barrel IF focusing ring) f/4-P model, which has a CPU in it. Last time I looked on
eBay they were bringing $2,000-$2,300, and the Sigma 500mm f/4.5 was also around the same price on
eBay. I do not mean brand-new, retail on either the Sigma 500/4.5 or the 500/4 Nikkor-P, but used lenses, sold by private party sellers, not "The Big Five" web dealers...
Sigma makes some decent offerings in price ranges/niches that the big camera makers tend to neglect, or price VERY high. Sigma makes A FEW superb lenses, like their EX Macro line; I'd also really love to have the new 120-300mm f/2.8 EX OS HSM model Sigma recently re-designed and added OS to. While Canon and Nikon work on oddball crap, Sigma comes out with a lens that is just about the ONLY 3rd party big lens I ever see at FBS-level college football and NFL games...their 120-300, either old or the newer model...
