SIGMA 18-50/2.8 or Nikon 18-70/f3.5-4.5

I still try to choose something simple for everyday photo.
And as always, money, money, money.......

Now I can't buy lens more expensive than a lens for 400-500$

What would you recommend?

Thank you guys.

Ihave actually seen more favorable reports on the Sigma 17-70mm lens. The sharpness of the 17-70mm is constantly mentioned.

It's also a macro lens to boot!

I'll be getting the Sigma 17-70 as my next lens.

Also consider the Tamron 17-50 2.8 (constant), I believe it's also very sharp.

There is no contest the Sigma 2.8is a cracking lens. I had one for 18 months on My D200 and D2X and it is an amazing performer, much better than the Nikon18-70 or indeed the Sigma 17-70, constant aperture is a huge plus. The 18-50 is nowalso a "Macro Lens":?

Unless you are desperate for the extra 20mmthe better qualitywill see you right. Just take a look at the MTF charts from sigma and Nikon.Butremember that at 18AND 50 the Sigma is at 2.8.and still compares favourably with the others at 4.5. At 4.5having already been stopped down significantly it is seriouslyimpressive andcould out resolvethe sensor.I now have the 17-55 Nikon and I think there is next to no difference in image quality. Ifyou want another opiniontake a look at this review comparing it to Canon L glass.

This puts the Sigma 18-50 against the 17-70, I found it very informative.
