    Hello everybody.

    I still have old Canon D30 and I' considering buying the Sigma 50-500 for
    that camera. How do you think: will it focus very slow on D30 ? If yes, I
    should rather consider buying a new body... Maybe someone remember how it
    worked with D30 ? I've got Sigma 24-70 3.5-5.6. I know it is not a top lens
    but it is fast enough for me and I would be pleased if the big sigma focused
    with similar speed. I've got also Canon 50mm 1.8 and speed of its focusing
    is a nightmare. It rotates few times before focus. It is strange for me
    because that lens is very bright so it should be faster.

    Thank you in advance for all your advices.

    Hi, I have just done a comparison test of my Sigma 50-500 on my Canon 10D
    and on my son's Canon D30. The test was done in dull cloudy conditions from
    inside my house focussing on my garden fence/shrubs 10 metres away (at
    6.30pm). Both cameras were used on the fully auto setting and the time taken
    was with the lens initially set at its closest focus position.
    The D30 took 1.1 seconds to focus at 50mm and 2.4 seconds at 500mm.
    The 10D took 0.6 seconds to focus at 50mm and 1.5 seconds at 500mm.

    Hope this helps with your decision!

    My old D30 would have struggled (before it fell ninety feet to it's
    death...see picture: http://www.pbase.com/markuson/image/37396350 Oops!)
    with that lens. Focus was always slow, but that lens would have been
    especially bad (if you consider 2-3 seconds bad...I consider it TERRIBLE).

  4. Just focus manually. Jeez! Do you have to have everything done for

    I have a D30 myself and I focus manually all the time. I'm just faster
    than most autofocus cameras I've tried, particularly in low light.
    Comes from years and years of practice.

    How many years have you practiced being an ass?
    Methinks that would also be, "years and years..."

    The post asked a specific question regarding speed of AF on the D30...
    ....NOT how fast some dolt named Stefan claims he can manually focus.

    You offer nothing here but your fool mouth.

    Take care...

    You should try a 20D or a 1 series with a 24-70 f2.8L, then. It'll rattle
    your faith in your speed.

    Sorry Stefan.
    I was in a really bad mood last night.

  10. Apology accepted. We all have a bad day every once-in-a-while. And my
    reply was not to the OP's query, but to one respondant's complaint
    about the slowness of HIS belated D30's autofocus.

  11. I tried a 10D last year. And about the same time, a Nikon D70. I
    played with a friend's Fuji S2 a few months ago. In bright light, they
    all are reasonably quick to focus. Not real speed demons mind you. In
    lower light or low contrast, autofocus response slows considerably. I
    wouldn't trust the autofocus on anything that required really fast
    focusing like sports, particular under artificial lights. Haven't
    tried the 20D. So, I can't say. Another friend just bought a Canon
    1Ds Mark II. He'll be coming into town in a couple of weeks and I hope
    he brings it. Would like to try it out. But for now, I'll stick with
    manual focusing with the D30 and my all manual, all mechanical Nikons.

    I have a D30, but I'm not sure what lens(es) you're using. The comparison
    in focus times in low light between that camera and, say, a 28-135 IS vs. a
    20D and a 24-70 f2.8L is marked. I was surprised at how much faster the "L"
    lens was than my 28-135 IS, both on the 20D. There is no way, even when I
    was young, and had young eyes, that I could have manually focused a lens
    nearly as fast, given a camera that was set up for manual focus. I
    certainly couldn't focus a D30, with it's lack of split screen or any other
    focus aid, that fast.

  13. I'm sure that with a faster, better quality Canon USM lens on my D30,
    instead of the Sigma 18-50 f3.5/5.6 DC on it now, the autofocusing
    would be much improved, but for now the Sigma/D30 combo satisfies my
    very modest, digital photographic requirements. Plus, I consider it
    foolish and a waste of money to put a $1200 lens like the 24-70 f2.8L
    on a 3.3 MP camera that only cost me $400. Now, if I had Canon AF film
    cameras, too, maybe, I could justify such a purchase, but all my 35mm
    film stuff is manual Nikons/Nikkors, most of which I purchased new in
    1978. Had to replace the original FM bodies with FM2n's a few years
    ago. Wore out the shutters.

    Guess my eyes are better than most my age. Had 20/10 vision when I
    entered military pilot training after graduating from college. (That
    means I could resolve letters on the chart at 20 feet distance that the
    average person with 20/20 vision needed to be at 10 feet to read
    clearly.) I passed the eye test without glasses for renewal of my
    driver's license a couple years ago. Surprised the hell out the
    examiner. Made me do it again, but with a different set of letters in
    the machine just to make sure I hadn't cheated. Only need "drug store"
    glasses for reading. So far, anyway. But I'm sure there's an
    optometrist lurking in my future.

    Well, I'm fast manually focusing, because I've had lots of practice
    shooting professionally long before there was auto-anything. It was
    manual only or not at all. However, I doubt that I could beat the
    newer pro-digital cameras in the focusing department, but hopefully
    I'll have a chance to try when a friend visits in a couple of weeks
    with his new Canon 1Ds Mark II.
