    Hi-Res Photos

    Here they are, for any remaining cynics of the crowd.

    The 70-200 f4 IS looks like a really nice lens. Too bad they didn't go a little longer with it. We'll have to see the reviews.

    The new XT is nice but nothing revolutionary. Still if the they fixed the AF, it will be a great entry level camera.

    Wonder what that round sensor-looking thing is on the front of the right hand grip? Odd place to put any sensor. Finger warmer?

    Pricing and availibility have been announced. Both come in November at the $1250 and $1600 price points respectively. That's a very tough sell when you can get the f/2.8 version for $1600.

    (Though in Canon's defense, the 17-40L debuted at $1200 and look what it's selling for now...)

    Jeff has posted Canon's press release on the new XTi:

    http://www.dcresource.com/news/newsitem.php?id=3370

    "At the heart of the Rebel XTi SLRís high-resolution image capability is its large, single plate, CMOS color image sensor. Designed and manufactured by Canon specifically for the Rebel XTi SLR, this highly responsive sensorís 10.1 million pixels are fractionally smaller than the pixels in the 8 megapixel Rebel XT model, yet deliver markedly improved resolution... The Rebel XTi SLRís CMOS sensor goes further still, maintaining an exceptional dynamic range while reducing the noise level that one might typically expect for a pixel size delivering such high resolution. Canon engineers and designers achieved this breakthrough in sensor design by reducing the space between the chipís microlenses while at the same time increasing the sensitivity of each photodiode. As a result, the camera achieves 20 percent greater resolution than an eight-megapixel sensor with comparable noise reduction and dynamic range."

    Well it sounds like they were aware that squeezing all those extra pixels onto the same size chip would increase noise from users like us about noise in our images.

    "Among the decidedly user-friendly enhancements built in to the new Digital Rebel XTi is the 2.5 inch, 230,000 pixel color TFT LCD monitor with its wide, 160 degree viewing angle. Indeed, this brilliant monitor is approximately 40% brighter at its maximum setting than screens found on the top-tier EOS-1D Mark II N, EOS 5D and EOS 30D digital SLRs."

    Better/brighter LCD than the 5D? Hmmm - this camera is looking better and better...

    "The self cleaning sensor unitís ultrasonic anti-dust shake activates automatically for one second whenever the camera is powered on or off, ensuring that the camera will be as relatively dust free as possible and can be activated at other times through a simple menu selection."

    Very cool.

    "Also migrating to the Rebel XTi camera from the upper reaches of the EOS Digital SLR line is Canonís flexible folder management system... and perhaps most importantly, the same high precision 9-point Autofocus sensor and AF unit found on the EOS 30D SLR. "

    Wow. Now that's very interesting. If the XT focuses as well as the 30D it could be a great deal, esp. with 10MP and all.

    "The EOS Digital Rebel XTi camera will be available for an estimated selling price $899* with the zoom lens kit, while the body only kit will carry and estimated selling price of $799*."

    Double wow.

    This will be my final update. I have obtained the weight, dimensions, lens diagrams and MTF charts for these lenses. Enjoy!

    My mate's 350D appears to have this same "button" on the handle grip.

    Therefore.....is it really anything new ?????

    Wow. Now that's very interesting. If the XT focuses as well as the 30D it could be a great deal, esp. with 10MP and all.
    To add on, this was from the whitepaper.

    The Digital Rebel XTi has the same 9-point AF sensor and
    AF unit as the EOS 30D, including the sophisticated dualprecision
    cross-type sensor in the center AF position.
    This represents a very substantial upgrade from the
    Digital Rebel XT. The XTi is the first entry-level EOS Digital
    camera to have an enhanced precision cross-type, center
    AF point compatible with f/2.8, a feature unique in its
    class. The XTi has some significant AF performance
    improvements over the Digital Rebel XT. For example, the
    XTi has the same wide-area focusing as the EOS 30D.
    With an f/2.8 or brighter lens, the center AF point detects
    focus with the f/2.8 light flux. The base line of the center
    AF point's vertical-line sensitive sensor is twice as long
    as that of an AF point compatible with f/5.6. This makes
    focusing detection more precise.
    The whitepaper also directly addresses the in-body IS issue. Very interesting.

    Some of Canon’s competitors have chosen to use in-body image stabilization. The technique
    involves moving the image sensor in a controlled fashion, based on signals from
    movement detecting sensors in the camera body. The obvious advantage of this system
    is that users have some sort of stabilization available with almost any lens they connect
    to the body. Short focal length lenses require smaller sensor deflections; 24 or 28 mm
    lenses might need only 1 mm or so. Longer lenses necessitate much greater movement;
    300 mm lenses would have to move the sensor about 5.5 mm (nearly 1/4”) to achieve
    the correction Canon gets with its IS system at the same focal length. This degree of
    sensor movement is beyond the range of current technology. Short and “normal” focal
    length lenses need stabilization much less often than long lenses, so the lenses that
    need the most help get the least. Further, in cameras with smaller than full-frame, 35
    mm film size sensors, equivalent focal lengths become longer, by a factor of 1.5 or 1.6,
    exacerbating the problem by making all lenses longer.

    Less significant but still worth mentioning is the fact that in-body stabilization is not visible
    through the finder, whereas Canon lens-based stabilzation definitely is. Also, while
    in-body stabilization works for many lenses, it does not presently work for all; high magnifications
    and macro lenses have caused it difficulties.

    In the Canon IS system, the Image Stabilizer has an actual
    lens group that can be moved up and down, or side-toside,
    in parallel to the imaging sensor or film plane. A pair
    of sensors in the lens can detect horizontal or vertical
    shake. Signals from these sensors are sent instantly to a
    microprocessor in the lens and analyzed. The microprocessor
    then causes a group of lens elements, held in
    place by a device called a coil, to move at the same amplitude
    and frequency of the shake to cancel it effectively.

    Canon is able to generate excellent image quality by stabilizing the image optically
    before it ever reaches the imaging sensor in a digital SLR.

    With the optical IS used by Canon, each lens with IS has a stabilizer unit designed for
    that lens's needs. The unit in a lens such as the EF 28-135 f/3.5-5.6 IS USM or the EF-S
    17-85 f/4-5.6 IS USM is vastly different from the powerful, broad movement stabilizers
    in lenses such as the EF 400mm f/2.8L IS USM or the EF 600mm f/4L IS USM. All over
    the world, photographers depend on Canon IS to help them achieve the highest possible
    image quality.

    At some point, in-body stabilization may improve to the point at which such technology
    may be appropriate for certain segments of Canon’s DSLR range. It would be senseless
    to rule out such a possibility. Even now, differences in unit cost are not enough to be
    significant factors in such a decision. The bottom line is performance.
    Sounds exactly what I said a few days ago.

    Finally, for those wanting to know if the body has seen any changes. I was wrong. There are some changes for the better.

    The Digital Rebel XTi is a compact, stylish and attractive DSLR that continues the design
    concept of its predecessor, the Digital Rebel XT. The exterior surface is now coated with a
    leathery paint finish to make fingernail scratches less noticeable. The Canon logo is a bit
    bigger to make it stand out better in retail situations (2 mm wider and 0.4 mm higher).
    To improve holding ease, a convenient new rubber slip guard for the thumb (back, top
    right) and a new grip shape in the back have been incorporated. The grip is also thicker
    by 1 mm. The texture of the mode dial has been changed. The Print/Share button is now
    on the upper left on the back of the camera where the digital control buttons are concentrated.
    Clearly separating the digital control buttons and camera control buttons makes
    the camera easier to operate. The new screen and the elimination of the bifurcated display
    give the back of the camera a cleaner and more integrated appearance.
