    Hi all.

    My second (but very similar ;-)) post to these groups & I'm (still)
    cross posting! Apologies for that, but I'm still not sure which group is
    best for my query.

    Hopefully this one will get past your filters!

    Please feel free to set follow-ups to the appropriate group.

    After many (10+) years of happy snapping on an ancient Canon AV-1
    (35-70mm), I've finally taken the plunge and gone Digital.

    After a fair amount of research I chose the Sigma SD9 with 17-35mm
    f/2.8-4 EX DG Aspherical HSM lens. This gives me a nice angle of view,
    together with the option of taking a 'normal' image.

    Now, I've had this a few months and would like to extend my range by
    purchasing a zoom lens for the camera. I've effectively narrowed this
    down to either of the following:

    Sigma 28-200mm f3.5-5.6 ASPHERICAL COMPACT MACRO
    Sigma 28-300mm f3.5-6.3 ASPHERICAL MACRO HYPERZOOM

    This primarily due to the exclusive cost of high-end EX lenses.

    Now for the queries:

    1. With the sensor being 1.67 times smaller than a 35mm film, are the
    distortions (barrel & pin-cushion) associated with the lenses above
    minimised because the image circle is correspondingly larger?

    2. With the added colour depth (possibly wrong terminology there), and
    sensor resolution being that much greater with the Foveon sensor, could
    this mitigate the reports of image softening that I've heard attributed
    to these lenses? Especially with respect to the post-image-processing?

    3. Finally, do any of you have experience with these lenses & am I going
    to be disappointed when comparing the images to those taken with my EX lens?

    FYI - I generally take images at MAX resolution, and print images no
    greater than A4 in size.

    Apologies for the long post, but TIA for any advice.

  2. Right - "advice" - so why did you put "advise" in the title?

    You should be advised that the use of either word is correct.

    No need to thank me for this advice.

    Well, he's right - I actually meant 'advice'.
    Late night,
    Long day,
    What can I say?

    Poetry?! ;-)

    My queries were answered on my original post in any case.

  5. OK, I'll bite - is "advise" for a noun a Britishism?

    No it's not. I think Nick is saying "advise" is correct if "help" is being
    used as a verb. There was no context to clarify it as in "[I need] help and
    advice please" rather than "Help and advise [me] please". The OP said it was
    a typo so now we know :)

    'Advice' is a noun, 'Advise' is a verb, 'Help' can be either.

    A symptom of my crappy day that I should probably have wrapped within



    but I did put in a smiley :)
