Nikon Lens Talk
I compared the following lenses at my disposal. The Nikon 18-200VR, 18-70 and the Sigma 70-300 APO Macro, all at F8, handheld at aperture priority, no post processing, JPEG large-fine. at 70mm.

1. 18-200 sharpest.

2. 18-70 slightly less but soft edge and 70-300.

3. Sigma 70-300 APO the same as 18-70 but with sharp edge. at 200mm.

1. 18-200 sharpest.

2. 70-300 The interesting thing I noticed was that 18-200 VR was about 1/3(-)ve EV as compared to the other two lenses. Hmmm!..

Hi sumeet, how does the 18-200 vr compare in size and weight to the 18-70 mm lens. I will be buying a D70s soon and would like to know if the 18-200mm is a lot bigger and heavier, or if there is little difference (it looks similar in photographs - but these can be deceptive)...

The 18-200VR is 27% longer and 34% heavier, but don't forget that it is an 11.1x zoom (versus 3.9x) and it has VR. Nikon AF-S 18-70mm f/3.5-4.5G ED-IF DX.

Length: 3".

Width: 2.9".

Weight: 14.8 oz. Nikon AF-S 18-200mm f/3.5-5.6G ED-IF DX VR.

Length: 3.8".

Width: 3.0".

Weight: 19.8 oz. People that own the 18-70mm often sell it after getting the 18-200mm. Maxx..

Slow 18mm-70mm lens f/3.5-4.5.

I am anticipating purchase of a Nikon D70s. The 18mm-70mm lens that is packaged with the kit seems very slow (f/3.5-4.5) That makes the D70s not much better than a point-and-shoot. I am considering the Nikon 17-55mm f/2.8 but that is big $$$$. Does anyone have any experience with the Sigma 18-50mm f/2.8 EX DC when used with the Nikon D70s???..

Huh? Not much better than a P&S? You still get much shallower depth of field with the D70s/18-70mm combo than with *any* P&S (except the Sony DSC-R1, but I wouldn't call the R1 a P&S), it's wider than most P&S's (27mm), has faster auto-focus, you can manually focus it if you like, plus with usable ISO 800 and 1600, you can still work in lower light than with a P&S. The 18-50mm f/2.8 is less than 2/3 stop faster at wide angle, and just over 1 stop faster at 50mm than the 18-70mm. I have no experience with the Sigma directly, but I've heard it is an excellent lens both optically and mechanically. It's a little slow focusing compared to AF-S Nikkors because it is not HSM, and it suffers from higher levels of CA than the Nikkor 18-70mm when wide open. Maxx..
