Strange Canon remote software....hidden AF function 40D

    The DPP of Canon is not able to make the 40D auto focus with Liveview.
    Strangely enough DSLR Remote Pro from Breeze systems can. Not only that, but
    it also has 2 ways for AF: what they call camera is phase detection: the
    normal way the mirror is flipped up and there is a way which resembles or is
    exactly like the tripod mode of the Nikon D300, also called contrast
    detection.
    So!
    The camera obviously can AF in Liveview with two different ways. But you
    can't use them, because Canon has forgotten to implement them in the system?
    A third party like Breeze systems seems to be able what Canon can't...
    Maybe it's time for some serious update, Canon? First of all in the firmware
    function that lets you choose between phase and contrast AF and an update of
    the EOS Utility to use AF in the Remote software.
    If you don't know how, ask Breeze ;-|)

    I don't understand Canon. This could be a great sales argument, because the
    Liveview mode would greatly benefit from it. Fantastic for studio work for
    example. It could be a competition killer.
    How can they not use that? I'm going to contact them.

    Use the Canon EOS-utility :)
    - choose 1 of the Creative Modes on the camera
    - connect camera to PC
    - EOS-utility starts (or start it manualy)
    - click "Camera settings /Remote shooting"
    - below, click 3rd button from left ("Remote LiveView shooting")

    Oops, that's what I mean. DPP is the Raw converter.
    Right, but how do you AF? Not there. You have to manually focus with some
    arrows. The Remote Pro has 2 different AF modes, contrast detect and phase
    detect. So if it's in the camera, why don't they use it? Seems a waste.

  5. Hi,
    i do not know this software, i´m curious to hear how this works. If you use
    that phase detect AF mode in the Breeze Sys software, does it move the lens
    focus motor itself? The only way that could work externally is that the
    software itself analyzes the liveview 100% magnified picture and controls
    the lens AF in a way that it rotates left or right and tells the lens to
    stop as soon as the software thinks the picture is in focus. Pretty clever
    in fact. I do not believe that there is a "hidden" or deactivated contrast
    AF function inside the 40D just like they have in the new 450D, but i guess
    they could patch it with a new firmware if they want (but Canon will not do
    this even if they could).

    It spares you the $95 DSLR Remote Pro :)
    And even Breezesys admits it could take several seconds to achieve optimum
    focus and it may even fail.

    With a little bit of experience focusing with the arrows is rather quick,
    within one and a half second.

    Maybe your eyes are better ;-)
    The contrast detect mode is very slow on the D300 too, so that seems normal.
    But the phase detect is just as quick as if you use the camera without a PC.
    Just the fact that a third party does this or can, makes Canon not look
    better.
    The Nikon remote software packs a lot more features, but then it's not free
    either...

    Hi,

    You can download a demo that will work for 15 days completely. Don' remember
    the site, but Google "remote software Canon" should be enough.
    Yes it does move the lens motor, how else can you get AF?
    And I can tell you: it works just as well or better than the remote software
    of Nikon (which is more expensive).

    I doubt that, a good optician does wonders:)
    I wonder how they do that: a software emulation of a hardware specific
    feature.
    It's free.

    I'd rate it worse than very slow - it's very nearly completely useless.
    With an F2.8 lens set at f2.8, then it takes forever and fails most
    times. Set to small aperture it works - sort of, but I'd trust focus
    accuracy much less with aperture set at F11 than at f2.8 (LV mode
    initiates with lens aperture as set on the camera body - which can't be
    changed after entering LV mode, except by temporarily exiting and
    re-entering LV mode - useful to know as you can see true DOF on the
    display - and zoom in to 10x to get a good preview of 1:1 view of the
    image).
    One thing it seems to confirm is that if a large sensor point & shoot
    camera was to be made, they'd have to use something much better than the
    contrast detect AF in the D300 to make the system work as an AF system.

    While you've got their attention, ask them to fix the bug in the latest
    version of DPP that causes it to crash when trying to read JPEGs produced by a
    Powershot S50. ;^)

    Yeah, I know I'm in danger of being seen as a fanatic on this issue, but I'm
    starting to conclude that with Canon the squeaky wheel gets the grease. (OTOH,
    I was treated very well by their Jamesburg shop the one time I needed service
    on a camera.)

    Yeah, with all the autofocus problems they had last year with the 1D3 (and may
    still be having?), I can see that they might not want to pry open that can of
    worms just now. ;^)
