    Default about the IS lenses

    how much stops an IS lense affect, compare a normal lense?
    Ex. if I shot with the 50mm, my secure shut has to be at least 1/80 (50x1.6=80 and we talking about my new 450d, APS), what with a 50mm IS?
    I bought a 55-250 IS, sure better than my old 75-300 II and it would cover the 60, 65, 70mm that sometimes I miss out...and...what do you think about that lense? its 55-250 IS 1:4-5.6?

    older IS is supposed to be two stops, the newer IS up to 4 stops. Not really got an opinion on the 55-250 but plenty of reviews around

    This site is good for straight 100% crop comparisons... Looks like a good companion for the 18-55 kit lens

    It realy depends on your technique and the IS.

    Also the subject has to be stationary (or close).

    I've shto a 25 second handheld river scene with the 2 stop IS on the 17-55 and it turned out ok...

    For technical reviews, I like photozone. For user reviews, try Fred Miranda.

    heaps of reviews, very nice articles.
    I guess I will discover it by myself, at the end of the day I will be the one to squeeze that lense, so, I will make it adjust to my works... or I will adapt to the lense?

    Just remember that if you are shooting on a tripod switch the IS off, otherwise it can get confused.

    How come the canon telephoto's (600, 800mm etc.) have IS then? Can't be for hand held(?) Just curious.

    I think they are valid to use on tripod they damp down any excess movement even on tripod.

    I think some of the modern ones will switch off IS if it detecs its on a tripod too (i.e. no movement).

    I did a simple test the other day using the VR feature on a Nikon lens, and I can say that the VR helped immensely when the camera was hand held. As for the tripod topic, I don't think I'll ever own a 600mm or 800mm lens so I can't comment
