    Still no IS !? Canon really does things so passive – gives no new features until Nikon does it~

    Really… No IS!!? 🙁
    Also whats the difference in those diagrams..? I can see anything radical.

    And size? Is the new one really going to be 17-20cm long??

  • Rod

    Nikon told recently (in photokina days to M Lammerse from DPReview) that there are difficulties in making this lens IS.

    No wonder no one didn’t make it, even Tamron, Tokina, Sigma didn’t offer an IS version.

    Even if they could add IS, then they would have two versions, like the 70-200, because they are very important zooms.

    Maybe the sensors will have IS eventually?

    You have bought into marketing hype if you think you need IS in a lens under focal length under 70. compare canon IS and non-IS version lenses, the non-IS ones have overall better IQ – are sharper – and have better saturation and contrast. please let the new 24-70 have no IS group in it. Stop being lazy people & bring a tripod.
