    Its good..just that when on crop, its around the same "width" as a typical compact camera.

    Might want to get the tamron 17-50 f2.8 instead.
    You wont see me much less remember me but i am the guy who makes you look good.

    I would find 24mm on crop a bit too tight for my liking. 17-55 is my sweet spot for crop. Your preference may vary

    Depends on individual preference really.

    Some math here:

    APS-C Sensors have a crop factor of 1.6
    Full Frame (FF) Sensors do not have to compensate.

    The EF 24-70mm f2.8L USM would have an effective range of

    24x1.6 - 70 x1.6 = 38.4mm - 112mm

    The Tamron 17-55mm f/2.8 would have an effective range of

    17x1.6 - 55x1.6 = 27.2mm - 88mm

    Try the EF Lens on a fullframe body (i.e. 5D) to see the difference; it'll be easier to know what you effect you are looking out for (:

    I quick like the 24-70 focal range on my APS-C cropped D90. i also have the Tamron 17-50, but always find it too short for portraits when walking around.

    The ultimate downside is the weight of the 24-70, its damn freaky heavy and have to be balanced with a battery grip..

    It's too heavy for walkaround. The 24-105 f4 will be a better walkaround lens.

    Hmm.. I have considered EF 24-105mm f4L IS USM too but how is the quality of photos EF 24-105mm f4L IS USM can produced?

    it's about the same (some say better) as the 24-70L, but with added IS. the thing is, it has soft corners, though not noticeable on a 1.6x crop. you only want the f/2.8 if you want a stronger bokeh, or when your subject tends to move more (if it really moves a lot, then i seriously doubt the advantage of just having one stop more).
    so i would say, go with the 24-105L if you like its weight and focal length.

    To optimise the efficiency of its hood, at 70mm its retracted back to its shortest length and thus the hood provides a deeper shade for it.. Not exactly like a Nikon, their zoom ring rotation direction is different but this design is a reverse zoom..

    You may find the 24-70 too restrictive/ not wide enough , as you know 24mm is 24 X 1.6 = 38.4mm. IMHO i would prefer either the tamron 17-50 or Canon 17-55 for a walkabout lens

    With a crop factor, I think the camera offers a pretty good range...with the low aperture value its also pretty easy to use it handheld at night at 400 ISO, you can still get decent pictures with it. As a walkabout, good lens, but if your shooting landscape from quite a distance (ex from hilltops), then I suggest you get some lens with a wider telephoto range.

    for me i will keep my tamron 17-50 than add another 24-70 to my collection of lens... norm i no not need 17mm wide end however when i need it, it doesnt justify me buying another 10-22 to cover that wider range i might occasionally need...

    how i wished there is a 24-105 f/2.8 IS USM... best of both worlds for me...

    i have the 24-70L as my standard zoom when I am on my 40D, with the EF-S 10-22 to cover the shorter end.
