    The angle of coverage of Apo-Sironar-N

    Is it 72 degree or 75 degree?
    According to the data sheets on linos website
    http://www.linos.com/pages/mediabase...r-n_e_2474.pdf
    On the first page it claims 72 degree, while on the second page it claims 75 degree.

    Yes it is really confusing, but it may be a printing error, because it was always 72 in the past!
    But the coverage is a bit larger anyway but it will then be a bit on the soft side at the corners.
    The 72 is the aceptable sharp part!
    On the S version its 75 as already stated!
    Hope it helps, Armin
