    My kit lens has IS on it and the 55-250 lens I was looking at has it. If I get a 50mm F/1.8 will it have it?

    Do I -need- it?

    I'm doing mostly pictures of people, but some landscapes etc. I'm just trying to get the best deal for my $ cause I don't have $ to spare. :lol:

    EDIT::::

    So, here's what I'm debating now (and I'm going to add this to the original post) With my budget (in october!) I'm thinking about getting the

    1} 50mm 1.4
    OR
    2} 50mm 1.8 AND 50-250mm zoom lens

    Suggestions?

    The 50mm 1.8 does not have IS.

    Do you need it? Well, that's hard to say. It can add up to 3 stops to handhold a lens. Normally you want to shoot at a shutter speed that is as fast as, or faster than the number that is your focal length. Thus, with a 50mm, you want to shoot at 1/50th of a second, or faster. I'm not sure if many cameras let you do this, so really you'd be shooting at 1/60th. Some say that if you have a crop sensor, you'll need to multiply the focal length by the crop factor to get a minimum shooting speed. So now, you're looking at 1/80 or faster.

    If you're using a longer telephoto, lens, the IS can really come in handy. It's hard to hold those puppies still, and you need a pretty fast exposure to overcome this.

    IS will only compensate for camera shake. It will not freeze movement in front of the lens. It is most helpful in low light conditions. It can allow you to shoot at a lower ISO, getting a sharper image. You never need IS if you are using a tripod.

    If you're shooting outdoors, in the daytime, with lots of light, you probably don't need it. If you're shooting inside or at night, and you cannot use a tripod, you'll probably find it helpful.

    Canons 50mm f1.8 doesn't have image stabilization.
    IS is really more important on the longer lenses.

    Yeah it becomes a problem when you have telephoto zoom really

    It's also useful on wider angle lenses than just tele zooms, for instance beign able to to take sharp handheld shots at 0.5s shutter speed @ 17mm to blur a waterfall - it's a lot easier than bringing your tripod everywhere.

    As far as I'm aware, no prime lenses have IS until you get up to the likes of the EF 300mm f4L IS or longer.

    Just a note, never use IS when using a tripod. It will hunt for shake and introduce blur.

    ^ Unless your IS lens is tripod sensing, which the majority of them now are.

    If you are not going to get any lens for a long while after this, of course go with number 2.


    Also, if you really do not know why you need to get the 50mm f/1.4, 50mm f/1.8 or the 55-250mm IS lens, maybe wait a little longer.


    I think the logic should not be ...
    "I save up X amount of money and I need to buy a lens since I now has $X."

    It should be ...

    "I find a limitation on my current photography equipments and that stop me from produce the result I want, let's save up some money so that I can buy that equipment and do what I want to do." (Of course, new equipment may require new skills.)
