    That math checks out nicely. This has got me thinking though – is the
    effectiveness of IS linear, I wonder at the longer focal lengths if one
    should be even more conservative. I haven’t tested enough to make a
    hypotheses, I just wonder. And I meant to include this in the video- if you
    are taking photographs of people moving, IS doesn’t help. Just something to
    keep in mind. Thanks!

    Aperture does not affect handshake – well maybe one could make the argument
    that with a very large aperture your depth of field is so shallow that you
    may move the camera enough that your focus is off, but that is a different
    issue. In low light conditions the sensor needs more time to capture the
    scene thus you get slow shutter speeds. Let me know if any of that is not

    Sounds quite nice. I doubt we will ever see in body IS on Canon as it would
    cannibalize their own lenses.

    If you are shooting with a crop sensor camera like the T4i or D5200 you
    need to multiple the crop factor 1.5 or 1.6 times the focal length on the
    lens, otherwise you have it correct.

    I posted a detailed comment on your facebook page, but basically focal
    length on lens divided by 5 gives the shutter speed for a 3-stop decrease
    with a Canon IS lens, correct? 40 mm focal length = 1/8 second for shutter
    speed at 3-stop decrease, 1/4 second for a 4-stop ISO decrease. Correct?

    Nice video! Btw, i having hard time deciding which camera to buy: 6D +
    24-70 II + 135L or 5d3 + 24-105 + 135L, almost equal price, i often shoot
    dancing. Opticaly 6D would be better, but AF on 5d3 very good. Can you give
    me advice?

  • By CameraRec Toby, June 17, 2014 @ 5:59 pm

    The AF on the 5DM3 is a significantly better for objects in motion, like
    dancers. I think the answer is pretty clear.

    thanks! )

    So let’s say I shoot at 55mm, then I would need a shutter speed of 1/55 or
    higher right? 25mm, 1/25 or higher and so on. I hope I got it right.

    thanks for the tip

    Won’t the aperture also affect hand shake? Is your “rule” assuming that you
    have a decent amount of light? Wouldn’t you need a higher shutter speed in
    low light conditions?
