    Incredible for the Money5
    You Must get it if you want a great lens for great money.

    Yea its not Canon but I can take alot of pics that turn out perfect with this lens.

    Great lens!5
    Have used the lens for several weeks and out in the wilderness for several trips. It is definately a tripod lese if you want to capitolize on sharpness. It does zoom and catch focus fairly well, but you should be adept at changing focus points or switching to manual if you are picking out subjects in wooded areas etc. The macro aspect of the lens is fantastic. Love the fact that it is black and slightly less obtrusive then the Canon lens. Does add a bit of bulk and weight to your pack! overall a superb value.

    darn good lens5
    I love this lens. I use it for weddings and portraits. It has great reach and awesome image quality. And, it's really heavy, so you can use it to work out with too ;D
