    Is this possible? Is it dangerous? Can you damage the camera? I've
    heard that the Rebel was somewhat sabotaged so it wouldn't make their
    other cameras look bad.

    Where to go for this hack? Do you need anything hardware specific to do

    Just Google "Wasia hack". I used it with no problems on my 300D. 3200 ISO,
    mirror lock-up, flash exposure compensation and several other features are
    unlocked by the hack.

  4. It wasn't "sabotaged" Canon simply took the 10D sensor and circuit and put
    it in a plastic body. Features of the 10D were turned off as it simplified
    the operation of the 300D. This due to economy of scale of using a proven
    circuit allowed Canon to break the USD $1,000 price point. To use the term
    "sabotage" you imply evil motives, I just see it as marketting. The 10D is
    still a better camera overall, but it can't use EF-S lenses like the 17~85
    IS, the 10~22 or 60mm Macro . . . so 300D owners win in that aspect.

    Same here.

    Read the README before you do it but the procedure is roughly this;

    Format a CF card in the camera. Turn the camera off. Move the card to
    your computer and copy the file you downloaded from 'net to the card.
    Put the card in the camera and power it up.

    Be patient if it doesn't appear to do anything. Make sure you have a
    batter with a good charge.

    Why can't the 10D use the EF-S lenses you list? They are for that size
    sensor (if I understand the Canon line correctly).

  7. The D30, D60 and 10D don't have an EF-S lensmount. The EF-S bodies have a
    shorter mount to mirror distance. So if you managed to mount them the mirror
    will hang up on the rear of the lens.

    Don't you just love logic? :) And thanks for the tips, people. Well

    Er, no, the lens mount to sensor distance is the same as any other EOS
    camera. It has to be, otherwise EF lenses would not focus on EF-S
    capable cameras. The rear element of EF-S lenses extends into the
    camera further than EF lenses, and the 300/350D, 20D, and 30D have
    smaller mirrors which will clear the lens rear element, but other EOS
    cameras would foul the mirror if an EF-S lens could be fitted.

    Although the 10D, D30, and D60 have 1.6 crop sensors, they were designed
    before the advent of the EF-S mount, so they are not EF-S capable.

  10. And I see most marketing motives as evil. "Sabotage" exactly fits
    deliberately crippling a piece of hardware. I feel the same way about
    computers (long ago) that could be made twice as fast by cutting one
    David Dyer-Bennet, May 8, 2006
  11. This can't be right; if it were, then some EF lenses could not be mounted
    on EF-S bodies; *only* EF-S lenses could safely be mounted. Which is
    clearly not the case.

    Wow, and people have problems understanding what lens works in what modes on
    a Nikon! Almost makes K, C, IC, AI, AI'd, AIS, AF, AF-I, AF-S, AF-D, IX,
    DX, and G seem simple. If I read you right, being EF-S capable is primarily
    due to mirror size...so the first 1.6 sensor bodies used FF mirrors??? Are
    EF-S lenses made such that they cannot be mounted on a non-EF-S compatible
    body (as a precaution)?
    george, May 8, 2006
  13. Yes, I think it was reversed above. EF-S bodies take all the EF-S
    lenses, and all EF lenses. EF bodies take only EF lenses, of which there
    are many, excellent to wholly indifferent.

  14. In either event, it doesn't fit the original meaning of the term,
    messing up your employer by throwing your shoes into the machinery.
    Unless there's an evil gnome in Canon, deliberately disabling marketable
    goodies to the chagrin of management.

    Right, marketing pukes refer to it as "defeaturing". They also
    use words like "positioning" and "differentiation".

    End result: identical

    You get a product that is technically capable of doing much
    more, but has been artificially hampered. Sabotage is a fairly
    close word for such an event.

    The EF-S lenses won't mount on a non-EF-S body. An EF-S lens' rear element
    extends further back in to the camera body and can block the mirror when it
    flips up causing damage to the lens, or worse, the mirror. The advantage to
    an EF-S is that since the lens is designed to produce a smaller image circle
    (for the APS size sensor), less glass can be used to lower costs. The
    disadvantage is that the smaller image projected makes the lens useless on
    35mm film or full frame digital cameras, unless you like vignetting.
    Personally, I steer clear of EF-S lenses since I occasionally still shoot a
    roll with my film camera to remember why I switched to digital.

  17. It's certainly possible, and as far as I know, no more dangerous than
    applying new firmware from Canon.

    You can get the hacked firmware here:

    Instructions for flashing new firmware onto the DRebel are here:

    I finally got around to doing this about a month ago, because I wanted
    mirror lock-up. The only feature I've actually used is the "high
    sensitivity" ISO 3200 mode (which I didn't think I'd ever use at all),
    though I did test mirror lock-up to verify it works. The good news is
    that I've used the camera heavily since installing the firmware, and
    haven't noticed the change at all; when not using the new features, the
    camera works exactly as it used to. Actually, that's not quite true;
    when a picture appears in the LCD preview immediately after shooting,
    and you hit the delete button, the UI defaults to "Delete" instead of
    "Cancel". Other than that, it's all the same.

    I've heard that this will technically void your warranty (if you still
    have one); I've also heard that Canon will provide warranty service
    anyway. As far as I know, the only risk is that if your CF card fails,
    or your battery dies, or you open the CF door halfway through the
    flash, or whatever, then your camera is hosed. Just like flashing with
    Canon's firmware.

  18. I meant to say EF-S have a shorter rear element to mirror distance, which
    will cause the mirror to hang. I over simplified my answer.
    Darrell Larose, May 9, 2006
  19. That's certainly true. But words evolve, and often mean different
    things than their early history would suggest.

    Goes all the way back to the Intel SX chip that was a DX with it's
    co-processor disengaged.
