    Default Canon 17-40 f4L or 17-85 f4-5.6 IS?

    hi frens,
    will it be a wise decision to change to 17-40 f4L from kit lens 17-85 f4-5.6 IS?
    like the "L" and and its full frame compatibility, but on the other hand, that kit lens has tighter zoom and IS.
    how good is 17-40 L lens over 17-85 kit lens?
    thanks for your inputs.
    regards,

    how do you define good?

    build-wise, weather sealed and solid 17-40 wins hands down.
    image quality wise 17-40 is better but not by a very large margin.
    versatility-wise 17-85 wins. It's a very good zoom range for a crop body,
    17-85 has rather good IS. 17-40's f/4 isn't really good indoors without IS.
    all in all, improvements you FEEL will be marginal.

    given the loss you have to bear from selling the kit lens, probably save a bit more and go for a second hand 17-55 or a 24-105?

    That's the way I went, instead of 400D Kit2. If you have the money, go for the L or EFS17-55IS. If you don't, stick with kit 1 18-55IS.

    since u can afford, the logical choise will be the newest EF-S 18-200 IS..

    why is it logical?

    for the TS,
    it really depend on if you are willing to sacrifice the extra focal reach for a better optics, build, lens without IS.

    personally i feel, IS does make a difference, but not too much on a wide angle lens. But if you like more reach and dont shoot in wide often, i will also suggest you to look at 24-105L IS usm. build optics and reach, without wide on apsc. it is actually a 17-85 on a full frame.

    I agree with Headshotzx.
    17-85 is not a fantastic lens to begin with. If you take my statement literally, it is still true, because optically at the wide angle 17mm end, it is quite bad There is very significant distortion, light fall off and some CA. You need to be at minimum 35mm before those stuffs disappear.
    So the humble 18-55 is more worthwhile to have.
    The best things in life are free.

    thanks frens,
    in this case i'd rather think of 70-200 f4L cos my determination to use an L lens is growing badly
    may be i'm poisoned!
    will stick with 17-85 for the moment since i normally don't use wide ends. only use 17mm for casual group fotos in which distortion is quite forgivable by the participants

    I have used both these lenses before and I'd definitely have to say the build quality on the 17-40L is second to none; it's built like a tank. The 17-85IS on the other hand, is pretty alright overall, nothing to shout about. Optical quality, the 17-40L is a visible step up from the kit lens for sure and is slightly sharper than the 17-85IS. If you have the money, get the EF-S 17-55IS, the image quality beats both these lenses, hands down.

    went out and tried 17-40. build like a tank? yesss . and it has huge front glass. 77mm?
    but zoom ring and focus ring are reversed to 17-85...i tend to turn the focus ring when i tried zooming
    placement of focus ring & zoom ring of EF and EF-S reversed?

    But it's a minor niggle which you will soon get use to. Besides, the focus ring on the EF-S lenses are smaller than those on EF lenses so it'll be easy to differentiate.

    don't have a lot but i'd go for 17-55 in exchange with the 17-85 kit. may be a used one
    17-40 seems a little short for me in long end and it does not have IS.
    thanks frens, for your kind recommendations
