    I don't have a canon so I don't know if this applies but generally the range is 2.8 @ 17 and 4.5 @ 70. I would try to look at a lens that is 2.8 constant.

    Some lenses are and some aren't...brand has nothing to do with it. It's better if it is...but those lenses tend to cost more and are bigger and heavier.

    I would recommend looking at the Sigma 18-50 F2.8 and the Tamron 17-50 F2.8. You would give up some length, compared to that lens, but you get a full F2.8 at all focal lengths.

    Thanks, I'm checking these out now.

    Tamron is $430
    Sigma is is $419

    So they cost the same, Anyone know which is better?

    I was debating between the two, about a year ago. At that time, the reviews that I read, mostly said that they were very close in all aspects...with maybe a slight edge to the Tamron. So I went with the Tamron.

    However, Sigma was releasing a new version of their 18-50 F2.8 'Macro'...and it was hard to tell if the reviews were for the new version or the old. The new version might be slightly better than the Tamron...but really, it's a toss up anyway.

    Maybe go into a store and hold them both, get the one that feels better.

    Thanks Mike.

    By chance do you have a link to the new Sigma Lens?

    NEW

    OLD

    I guess the difference is the addition of an HSM focus motor...and maybe something else (I didn't read all the details).

    Thanks Mike!

    I noticed the other post with this lens
    tamron 28-75 f/2.8

    Which would you go with? It looks like that has more length and 2.8 at both ends.

    The ones I linked to, are F2.8 at both ends as well.

    Sigma has a 24-70 F2.8, and as you have seen, Tamron has a 28-75 F2.8...both with constant F2.8. They are fine lenses...and yes, obviously longer than the 17-50mm range. However, I find that 24mm just isn't wide enough when using a crop body (any of the digital Rebels or 10,20,30,40D).
