Canon 90-300 or Sigma 70-300 ?

    I have a Canon 300D (with 28-90 kit lens) and would like to buy a larger
    zoom lens.

    I don't see the point of waiting for EF-S lenses to come on the market so I
    have narrowed the selection down to either a Canon 90-300 (f4.5-5.6) or a
    Sigma 70-300 (f4 - 5.6). The Sigma also has a macro setting and is cheaper
    than the Canon.

    Of course you need to multiple each lens by 1.6 to get the actual focal
    length for the Canon 300D.

    Any recommendations on which one to go for. The Canon will leave a gap of 90
    to 144 focal length between the 2 Canon lenses.
    The Sigma will leave a gap of only 90 to 112 between the smaller Canon kit
    lens and the Sigma zoom lens.

    Also, is there a great difference in quality between the 2 lenses? I will
    not be producing professional photos but would still like to be sure of
    getting very good resolution shots.

    Hi PeterH,

    what a coincidence, I was in exactly the same boat this week, with a skiing
    trip coming up I wanted a telezoom for my new 300D too. didn't want to
    spend loads cos I wanna spend money on hols :0)

    I looked at the same two lenses and bought the sigma, for two reasons,

    1) there is less of a "gap" between 55mm on stock lens and 70mm on sigma
    (than 90mm on canon)

    2) it was considerably cheaper 149 UKP v 220 UKP.

    I've not used it much yet (curse those winter evenings) the macro mode seems
    good though.

    One thing to be aware of is that mine is really "sticky, notchy, jerky"
    between 200mm and 300mm, Jessops (where I bought it) have agreed that is not
    right and have ordered me a replacement (allowing me to continue to use the
    duff one in the meantime). May be worth checking yours if you go this

    If I get the chance I'll post a couple of images on my website this weekend
    for you to see.

    Let us know which way you go.

    Please note, I'm not saying the sigma is beter or the opposite, just that it
    fits my requirements at the time.

  3. Note, without image stabalization on the lens (which adds to the cost) the
    usual rule of thumb is you need to use a tripod to avoid camera shake if you
    cannot get a shutter speed of 1/focal-length, ie 1/500 second or faster with
    either lens. I've read that Canon IS lenses give you about 2 stops worth in
    avoiding camera shake (though it does nothing for subject movement obviously).
    If you need to shoot handheld at slower speeds (perhaps as slow as 1/125 for
    full zoom), the 75-300 IS lens might be the ticket:

    When did Canon start making a 90-300 lens?

    Got out this morning while the sun was out, snapped these which may give you
    some idea that the lens isnt too bad.

    quality is good on originals but adobe Album seems to add noise when it
    reduces images.

    Lemme know what you think.

  9. This is very important when dealing with third party lenses. The quality
    control is not that great. You may luck into a good one, maybe not. I think
    a lot of people just live with the problem, not realizing that something is

    IMVAIO, the money you "saved" will be soon forgotten, but you'll be stuck
    with that lower quality Sigma lens for a long time.
