    Hello: I am making the switch from digital point and shoot to SLR. I just got back from vacation (Disney World) and noticed that more and more people are getting into SLR cameras. I also noticed this particular type
    of lens being used everywhere. What type of lens is this with the end of the lens having the cut outs? Thanks

    It's a wide-angle lens with a constant aperture. I wouldn't recommend this lens to you, because from what it looks like, you're not familiar with the technical aspects of photography, and this lens is kinda pricey. But I guess it depends on what kind of photos you are planning to take.

    Thanks - I just saw lots and lots of people with this type of lens. What would be the practical use for this type of lens? Thanks again!

    Mostly landscape shots, maybe full-body portraits.

    There are actually a lot of lenses that have a hood like that. Is it possible that it could have been a different lens with that kind of hood?

    What you're describing isn't a lens, It's a lens hood. They're meant to block the sun's rays and spurious glare, to keep them from entering the inside of the lens barrel and causing spots and reflections.

    Some have the cut out areas like the one you showed. Some are even all the way round with no cutouts.

    Generally, the ones with cut outs are for wide angle lenses.

    Useful outdoors in bright light. Pretty much useless any other time.

    Many people will keep them on the lens though, because they think it makes them look more professional or something.

    When using the camera's built in flash, however, a lens hood can cause problems because it sticks up high enough to block some of the light coming from the flash.

    ....so this is an attachment that is placed on the lens that can be removed? Thanks

    I imagine if it was not removable then that lens would only be able to be used outdoors?

    Actually, The hood would slide forward for use, and when you wanted to take pictures that you didn't need it for, you could slide the hood back over the lens barrel.

    Some people keep they're lens hood on, (Even if they don't need it for the pictures) to help protect the lens in case they bump it against the wall or something. People like me who are paranoid of hurting they're gear they have saved up for a long time.

    Just think of the lens hood as a baseball cap to keep light out of your eyes. The hood usually (from my experiences at leased) doesn't do anything to the picture if you don't need it...Unless your using on camera flash I guess, it could make a shadow
