    I just bought a Canon 550D 18-55mm kit.

    I find this lens is good but very limited to what I want to do.

    I'm interested in finding an affordable Canon macro lens? Could somebody please recommend one? Also a wide angle lens for landscapes? also a fish eye for some fun.

    Also what does it mean when the camera lens has a 1.4 , 1.8 , 2.8? is the lower the number the better or the higher? I know this sounds silly bu I have no idea!

    I also just found this is interesting , Re: crop factor.

    What type of macro photos are you planning to take? Flowers, insects or stationary object such as coins?

    If you are planning to take a detail macro photo of something that is very small such as close up photo of a fly, then I will suggest to get a macro lens that can do 1:1 ratio.

    1:1 means the size of the object image projected on the film/sensor is the same as the object.

    There are quite a few of those true macro lenses to choose from. The focal length of those lenses varies in general from 50mm to 180mm
    i.e.

    EF 50mm f/2.5 macro
    EF-S 60mm f2.8 macro USM
    EF 100mm f/2.8 macro USM
    EF 100mm f/2.8L macro USM
    EF 180mm f.2.8 macro USM


    Other popular third party macro lenses are
    Sigma 70mm f/2.8 macro
    Tamron 90mm f/2.8 macro
    Sigma 105mm f/2.8 macro
    Sigma 150mm f/2.8 macro
    Sigma 180mm f/3.5 macro


    The longer the focal length of the macro lens, the farther away from the subject from the camera. If you like to take a photo of a bee or wasp, a longer focal length lens make you feel more comfortable.

    As for the 1.4, 1.8 or 2.8. That is the maximum aperture size of the lens for a given focal length.

    i.e. EF 100mm f/2.8 USM lens. Max aperture you can use with this lens is f/2.8 (wide open) But of course, you can choose f/14 if you like such as when you taking a photo of an insect and like to increase the Depth of Field. (wider aperture, lower f number give you shadower Depth of Field.)

    As for wide angle, does the 18mm focal length wide enough for you?

    the shots you like would all pretty much be possible with a regular 1:1 magnification macro lens - so pretty much any lens that Dao lists above will achieve those results - provided of course that you control the lighting, setup and find the bug for the shot :)
