    I am trying to decide between the 2 above lenses and would welcome opinions. I have a 18-135 kit lens with my 70d which I think is a pretty decent lens for a bundle job, a 10-18mm that I Co fess I have never used, a nifty 50 and a 100-400mm L series.I thought I had decided on the 17-40 but now I am not sure.

    I personally wouldn't bother with either, given what you have - can't see what gaps they fill, and the lenses you have are pretty decent. The 17-40 is at it's best stopped down to f8 or f11 on full frame, and the 24-105 is also a much more useful focal length range on full frame IMHO. You have a sensible set of lenses for a 70D.

    Buying a 100mm macro would give a new option....a whole new world. It would also give you short tele without having to lug a round the 100-400.

    But the 18-135 has the short tele covered nicely.

    I've owned both of these lenses (Note: the Mk1 24-105mm, not the Mk2), and wasn't much impressed with either. I didn't like the in-use feel of the 24-105mm (zoom ring 'throw' too cramped, particularly at the wide end), and I didn't like the rendering of either lens.

    I eventually decided to migrate to all EF prime lenses, and have never regretted the decision.

    I have to agree with Nick. I own both of the lenses that you are considering with a full frame camera. With your camera and your existing lenses I'm really not sure I'd see the need for either of them. If you really have an itch for a new lens I'd be inclined to agree with AGW and go for a macro option. I use mine a lot.

    Yes, the EF 100mm macro (whether IS model, or not) is a superb lens, with virtually flawless performance. The non-IS version can also be obtained relatively inexpensively.

    I have both the EF-S 18-135 and the 17-40 L (I share lenses with my wife and call me OCD if you want, but I can't have duplicate lenses) and I'll reach for the 18-135 given the choice. Like everyone else I can't really see you need either lens that you're considering, so save your money, but if you really need to scratch that itch then a macro lens would be a nice addition to the team. Either Canon's 100mm or Sigma's 105mm (I have the latter).

    What's not clear is why you are trying to decide between theses lenses. Clearly you quite happy with the 18-135 so what is the appeal of this pair? As already said both are really for full frame and aren't optimised ranges for APS - the 24-105 will lose you reach at both ends of the range compared to the 18-135 and while the 17-40 matches at the short end it's well off the pace in terms of long reach.

    I have used a 28-105 (and even the very early 35-105) with APS format and neither is ideal as an all purpose lens, particularly if you are a frequent user of wider angles. The 24-105 has a slight advantage over the 28-105 but even then 24mm is hardly wide angle on APS-C. Unless you have an intention to go full frame in the near future I reckon a rethink is on the cards...

    It's probably fair to say that they are among the least impressive L lenses; the 17-40 isn't great wide open, but is a lovely landscape lens stopped down on full frame. Completely outclassed by the 16-35mm f4 IS lens. The 24-105 has quite a bit of distortion, and I replaced that with the 24-70 f4, which is quite a bit sharper, too, but above all, has a near-macro setting. The improvement between the zooms of 10+ years ago and the more recent ones is incredible; even some of the consumer lenses, such as the 18-135, are in the same ballpark as the older L lenses these days IMHO.

    Yes, I can quite see that this could be the case. I'll take your word for it, as it's actually about 10 years since I last bought a zoom EF lens.

    Having said that, I'm staying with my EF primes... essentially because I much prefer using them. :)

    In your case neather... I would rather have a look at the EF-S 17-55 f2.8 wich is arguably the best lens you can get on a aps-c Canon. Personally I went for the exelent EF-S15-85mm both of these are L lens quality and will outgun the 17-40 L in every way.
