$1000 Sigma lenses for Nikon D40x or NikonD80

I was wondered a big popularity of shot-cut Nikon’s SLR D40 and 10-megapixels Nikon D40x. For more about Nikon D40x look at Canon EOS400/XTi, Nikon D40x and Pentax K10 pros& cons; SLR over SLR-like triple benefits. But when I was surfing in the Net and was talking with salesmen I saw that a lot of users want to have a small and cheap Nikon’s SLR. Other users were buying D40 such as second SLR (first is Nikon too). It is natural that majority of new Nikon’s users love their first SLR cameras. And it’s unreal to have some critical points from them. Especially it’s unreal to have some critical points from those who chose Nikon long time ago and bought second Nikon. But there are two bad points which were significant even for Nikon’s fans: the AF is not good on moving targets and the majority of Nikon’s lenses can’t work with D40 and D40x. Only special lenses are recommended for those SLRs.

Look through these lenses (especially its prices). I think that Nikon D80 for $859 is much preferable for these Sigma lenses than Nikon D40 for $518 or Nikon D40x for $635. Look through Sony A100 vs Nikon D80 more worthy than Sony A100 vs DSC-H9/H7.And there isn’t Telephoto Zoom lenses for more than $1000 in this post. I will write about lenses such as Sigma 120-300 mm F2.8 DG for $2700 in my next post. And I think that cheap (short-cut) Nikon with only special (expensive) lenses is nonsense. But it’s only my opinion.
