    Bought for a fren this Sigma 150-500mm F5-6.3, now with me till end of the month.

    Size comparison vs the DA*300


    Some sample shots, all @500mm handheld:

    1/500s, F6.3, iso 3200


    1/500s, F6.3, iso 800


    1/500s, F6.3, iso 1600


    1/320s, F6.3, iso 640

    Hi Ken,
    The speed almost same at 1/500 except last one at 1/320 & f stops at 6.3, but the iso varies.
    What setting you used?

    I'm using TAv mode, fixed the shutter at 1/500s, Aperture at the minimum, Auto ISO (80-6400)
    Since the bird is bigger than the rest for the last pic & not much movement, I lowered the shutter speed to have a lower iso.
    For this lens, was said to be sharper at F8 but I try not to use this setting when the lighting is not so good (this month usually cloudy ) , furthermore the iso will be higher for F8 compared to F6.3

    You should try this mode, very useful as it will give u the lowest possible iso.
    eg. iso 1250 instead of 1600, iso 4000 instead of 6400.

    However if the lighting is very bright wll end up over exposed (if it's below iso 80).

    thanks Donald. This one, aimed and shoot. With tripod and still air.

    F4 is wide open for A*200 f4. The oof (bokeh) here is the properties of this macro lens.

    F16, flash lights and monopod. PP picassa. iso about 1600. 1/60 secs.


    29dec k5 vivitar kota tinggi 108.DNG-1 by luctomar, on Flickr

    took this in kota tinggi, same local robberfly which can be found here. K5 is great being high iso 1600 is usable and that allows a higher shutter speed to be used with f16, which is otherwise not possible with my K10 d or K20 d which I believe. Colors output is great as well.
