Hi all,

    I just bought a used Canon Rebel Xti. My Sigma 5omm 2.8 macro lens
    from my 35mm Canon camera fits but can only be used with an aperture
    of 2.8. (Sigma has told me that since it is an old lens this is the
    only way that it will sync up with the digital body.) 

    I am really a moron when it comes to understanding photography. (I
    rely on the fine services of my photographer to document important
    work such as anything intended for publication, jurying, etc.) I
    intend to take technical shots for teaching (which I have done with
    this lens and my old school 35mm.) and for documenting work when I
    can't get to my photo guy. 

    So my question: How important is it to be able to have the full
    aperture range? 

Thanks.
Andy
