    Nikon 18-70 f/3.5-4.5G IF-ED AF-S DX
    Sigma 17-70 f2.8-4.5 DC Nikon Digital Macro

    Pretty similar price & specs, the Sigma says 'macro', the Nikon goes as
    close as 15 inches. The sigma is faster to f/2.8 but I'd bet that
    doesn't buy any real improvement and it's probably not too sharp wide
    open. Mainly the problem with Sigma is resale value won't be as good and
    generally poorer build quality, possible future incompatibility.

    Perhaps consider this one as an option for $100 more and less range, you
    would actually get some improvement over the Nikkor:
    Sigma 18-50 f/2.8
    50mm is not that limiting and you'd have f/2.8 through the full range.

    Then you'd be looking at one of these:

    Standard Zoom Lenses
    *24-85mm f/2.8-4D IF AF Zoom-Nikkor
    24-85mm f/3.5-4.5G ED-IF AF-S Zoom-Nikkor
    *28-70mm f/2.8D ED-IF AF-S Zoom-Nikkor
    28-80mm f/3.3-5.6G AF Zoom-Nikkor
    28-105mm f/3.5-4.5D AF Zoom-Nikkor

    Where the 'normal' telephoto second lens is often:

    *70-200mm f/2.8G ED-IF AF-S VR Zoom-Nikkor
    or 80-200, 80-300 or whatever if $1600 is too steep

    Thank you for the quick and comprehensive reply!!
    You did not address focusing speed and accuracy; are they about the same, as

    The Nikon 18-70 is one of the stellar bargains ever offered by Nikon.
    If you cannot discern for yourself why you would want a different lens then
    this is a no brainer: get the Nikon 18-70.
    You will not regret it.

  5. These lenses seem to go for pretty similar amounts for what seems a pretty
    similar spec. They both have a 4.5 max aperture at the long end (the end
    that counts), so I'd go for the branded lens rather than the off-brand.
    It's a budget good kit lens, probably one of the best in fact.

    I haven't used the Sigma, but from what I've heard it doesn't match the
    Nikon 18-70 kit lense.

    The Nikon 18-70 is one of the rare gems you find that performs extremely
    well for the price. It's sharp wide open, has fairly low CA, moderately
    low distortion, and covers a useful range.

    If you're not sure, get the Nikon - it's a proven performer.

  7. The Nikon lens is the best choice - their 18-70mm zoom is sharp at all
    apertures, low on distortion, and its focusing mechanism is 'whisper quiet'.

    Takes good pictures too :)

    Just a question from a newbie. Here in Belgium, D80 will be sold with a
    18-70mm zoom or a 28-200mm zoom for almost the same price. Does someone
    knows if the quality of these lens are close. I read that it's probably
    the first time that Nikon provides a so good quality low-cost lens. Is
    it also the case for the 28-200mm. Thanks in advance. I know that this
    topic is out of scope of this discussion. Sorry

  9. The 28-200 is an old design without the 'silent' motor for focussing. I
    was looking at that lens myself but compared to the 55-200 its slow to
    lock in and quite noisy. Personally I'd go for the 18-70

    I'm really sorry, I was talking about the 28-135mm instead of 28-200mm.

    I got my D70 with a 28-200 & the big bummer there was lack of wide angle

    Looks like that 28-135mm is a $240 Sigma lens, not the $320 Nikon bargain.

    The Nikon 18-70mm is considered one of the best mid-range zooms ever
    produced by Nikon (or anybody else, for that matter). This lens is
    destined to become a true classic.

    The only reason to consider not getting it is if you are going to get
    the 18-200mm AF-S VR, a much more expensive lens but one that is
    unsurpassed in utility and versatility.

    At first glance the Sigma appears to perform the same on the Photozone
    site, but the charts are not directly comparative. You have to examine
    carefully to realize that the Sigma appears to have the same optical
    performance, but in reality it doesn't.

    Look closely at the chart lines and you'll see the Sigma is at 1850
    while the Nikon is at 1950. The number ratings show the actual values
    and the Nikon is rated better. CA is also much better controlled with
    the Nikon.

    The only point where the Nikon looses out to the Sigma is vignetting
    wide open. But close down one stop and the Nikon balances out with the

    The Sigma has an aperture of f/2.8 at the wide end, but edge
    performance is poor which tends to negate the aperture advantage (a
    consistent level of sharpness gives the impression of better image
    quality over a sharper center with soft edges). You'll want to stop
    down with the Sigma but you can happily shoot with the Nikon wide

    Usability features is also the area where the Nikon beats the Sigma.
    The Nikon has internal focusing with a fast and silent motor. Both
    have a non-rotating front element, but the Nikon has full-time manual
    focus override as well.
    I agree.

    It's pretty clear the Nikon has better sharpness, contrast, and CA
    performance, and better usability features, all at the same price as
    the Sigma. Nothing to think about there...the Nikon is the better

  16. Yep. A no-brainer.

    I just bought one of these lenses for my D70 & tried it out today. It's a
    very useful zoom range & there is no problem with the quality ,cheap at
