    Lens: all Nikkors
    50mm f/1.8
    75-300 f/4.5-5.6

    I'm looking for my next lens, which has to be on the wide angle side, since I cannot work indoors and do studio shooting with these two lenses that I have right now.
    I'm going to sell the 75-300 to get some money to buy the new lens.

    First of all let me tell you that I'm from Uruguay, South America.
    I can only buy stuff in USA whenever somebody that I know is traveling there, so he/she can bring it back to me.
    I cannot ship stuff to my house because customs charge me 80% over the cost and s&h, and the "gift" trick doesn't work.
    Talking about money, the Nikkor 18-200 VR is totally out of contest, it's way to expensive for me.

    There's a mate that has another D70S and a 18-70, so I already know how this lens performs.

    I've read many things about the Sigma 18-125 and 18-200 and I'm a little bit confused.

    18-70 vs 18-125
    - I know the Nikkor has a faster AF, but I would like to know how slow is the Sigma, can it be compared to the 50mm's speed?
    - Which one gives sharper images?
    - Which one gives better colours?
    - I don't want to sacrifice image quality for having just a little bit more range.
    - I don't care about focusing noise.
    - some say that some of them have a focus problem, you can either get a good sample or a bad one.
    - some say that the bad samples are just the ones for Canon, what about the ones for Nikon?

    200 better than 125:
    Some people say that it's better, but...
    - I've seen some photographs with more CA.
    - It's softer.
    - More on the tele side, but some say that it's really a 155mm
    - More expensive

    In case I'm getting the lens over here, the 18-200 is discarded due to its high price (200 US$ more), but if I can get somebody to bring it to me from USA, I'm going to take it into consideration.

    Prices here
    Nikkor 18-70 - 400 US$
    Sigma 18-125 - 400 US$
    Sigma 18-200 - 600 US$

    Any help and comments are more than welcome. :)
