larsen 0 Posted January 25, 2008 Report Share Posted January 25, 2008 Not sure why they've done it, but Canon's new basic DSLR the 450D has better specs than their more expensive 40D. That said the new Pentax K20D looks better than both. Time will tell. Quote Link to post Share on other sites
Dawn B 212 Posted January 25, 2008 Report Share Posted January 25, 2008 Look at the frames pers econd in comparison 3.5 on the 450D and 6.5 on the 40D. The focusing points are better on the 40d too. It also has better inbulit processing software. Cannot comment on pentax as I am not a fan and have never owned one. Dawn. Quote Link to post Share on other sites
larsen 0 Posted January 27, 2008 Author Report Share Posted January 27, 2008 True the 40D has as faster frame per second capabilities, unfortunately many Canon lenses, including some L lenses, can only produce 3 frames a second at tops. Not seen any samples of 450D yet to see how its IQ compares with the 40D. The 400D and 30D were very similar despite the latter having better inbuilt processing; Canon's always produce good cameras. However, the Nikon D300 and Sony A700 are the best cameras on the market (excluding the mega expensive) and the Pentex K20D will be the best value for money camera on the market shortly. All of which is good for us users. Quote Link to post Share on other sites
IanB 0 Posted January 27, 2008 Report Share Posted January 27, 2008 Taken from DPReview: Pre-PMA 2008: Canon has today announced a new compact digital SLR, the twelve megapixel EOS 450D (Digital Rebel XSi). On the surface a very similar camera to the EOS 400D, however there are a range of significant improvements; twelve megapixel CMOS sensor, 3.0" LCD monitor, Live View with both AF modes (contrast-detect and passive), 14-bit processing and RAW, spot metering, improved AF, 3.5 fps continuous shooting, a larger viewfinder, SD/SDHC storage and a new higher capacity battery. All in all a fairly impressive range of usage oriented improvements and refinements. Amstelveen, The Netherlands, 24 January 2008: Canon today launches its latest D-SLR, the EOS 450D. Featuring a 12.2 Megapixel CMOS sensor, EOS Integrated Cleaning System, 3.0†LCD with Live View mode and a new 9-point AF system, the model presents consumers with an unprecedented level of image quality and versatility at this end of the market. The EOS 450D employs features already proven in Canon’s professional EOS-1 series cameras, including the DIGIC III image processor and a redesigned menu system that enables features such as direct control of Speedlite flash units from the camera LCD. A choice of 13 custom functions allows the photographer to customise the camera to their shooting style. “The EOS 450D bears the fruits of more than 20 years of ongoing investment into EOS,†said Mogens Jensen, Head of Canon Consumer Imaging, Europe. “This camera continues Canon’s policy of taking technologies proven in the professional arena and putting them within reach of a wider market of amateur photographers.†The EOS 450D features: 12.2 Megapixel CMOS sensor Canon’s EOS Integrated Cleaning System 3.5 frames per second 3.0†LCD with Live View shooting 9-point wide-area AF system with f/2.8 cross-type centre point Picture Style image processing parameters DIGIC III image processor Digital Photo Professional RAW processing software1 Compact and Lightweight body Fully compatible with all Canon EF and EF-S lenses and EX-series Speedlites The EOS quality advantage With all key components developed and manufactured in-house, EOS offers photographers a unique quality advantage. The EOS 450D’s specially designed 12.2 Megapixel sensor employs Canon’s high-sensitivity, low-noise CMOS technology to produce richly detailed images with minimal grain. The DIGIC III processor ensures superior image rendering and rapid response times, with an almost instant 0.1 start up. Image data is processed at 14 bits for Delivering a burst rate of 3.5 frames per second, the DIGIC III processor works with the image buffer to handle up to 53 JPEGs (6 in RAW) without interruption. Built for better photos The EOS 450D is designed to make photography a fluid experience for photographers of all levels and experience. Housed in a compact body that weighs less than 475 grams, the camera features an improved grip design that provides a natural, ergonomic fit with the user’s hands. A large, bright viewfinder makes image composition clearer and more comfortable. The menu system inherited from professional EOS cameras uses a simplified tab structure that does away with scrolling. It includes a user-defined My Menu tab for instant access to frequently used settings. Several custom functions are available to optimise the quality of photos captured in a range of situations. Highlight Tone Priority boosts the dynamic range at the highlight end, providing better tonal detail from wedding dresses, cloudy skies and other bright objects. The new Auto Lighting Optimiser corrects brightness and contrast during image processing, while improving skin tones in portraits by ensuring correct exposure for faces. Photographers can also enable additional noise reduction for shots captured at high ISO speeds. Live View Available for the first time on a Canon consumer D-SLR, Live View mode makes it easier to shoot from awkward angles, such as ground-level macro shots or when shooting from a tripod. The image from the Live View mode is displayed as a smooth, 30fps video feed on the 3.0†LCD, which is 50% brighter than the screen of the EOS 400D. A grid line display and live histogram can be selected to help with shot composition and exposure. While focusing, the photographer can zoom in on specific details with up to 10x magnification of the image displayed on the LCD screen. Two types of auto focus are available: Quick AF flips the camera mirror momentarily to engage the AF sensor; Live AF uses the image contrast data to focus - a method familiar to anyone upgrading from a compact digital camera. For studio environments, remote Live View lets the photographer compose, adjust settings and capture the shot from a PC using the supplied EOS utility software. Other improvements The EOS 450D complements its headline features with a host of smaller improvements that enhance the photographic experience. The viewfinder now displays all key exposure information including ISO speed. The addition of spot metering (4% of viewfinder) allows for greater control over exposure in tricky lighting conditions. PictBridge functionality has been expanded so that photographers can correct horizons and add picture effects before printing. A new high capacity battery extends shooting time on a single charge to a maximum of 500 shots. CMOS Canon’s CMOS technology is one of the company’s key competitive advantages, with noise reduction circuitry at each pixel site delivering virtually noise-free images. In comparison with CCD technology, the lower power consumption characteristics of Canon’s CMOS sensors also contribute to longer battery life. Signal conversion in Canon’s CMOS sensors is handled by individual amplifiers at each pixel site. Unnecessary charge transfer operations are avoided, vastly speeding up the process of getting signal to the image processor. Noise generation is reduced, power consumption is limited and faster frame rate potential is increased. EOS Integrated Cleaning System The EOS Integrated Cleaning System combats sensor dust in three important ways: Reduce, Repel and Remove. Reduce - Internal camera mechanisms are designed to minimise dust generation. The redesigned body cap prevents dust generation through wear on the cap itself. Repel - Anti-static technologies are applied to the low-pass filter covering the front of the sensor so as not to attract dust. Remove - A Self-Cleaning Sensor Unit uses hi-frequency vibrations to shake dust from the infrared filter for a period of approximately one second after each start up. For instant shooting after power up, this feature is disabled immediately the shutter release is depressed. Canon has also developed an internal Dust Delete Data system, which can map the position of visible dust on the sensor. This can then be deleted automatically after the shoot with the latest Digital Photo Professional software. Picture Style Picture Style pre-sets simplify in-camera control over image qualities. Picture Style pre-sets can be likened to different film types – each one offering a different colour response. Within each selectable pre-set, photographers have control over sharpness, contrast, colour tone and saturation. The camera’s factory default configuration is set to deliver immediately-usable JPEG images without need for additional menu settings. Picture Style presets applied to a RAW image can be revised with Canon’s Digital Photo Professional software. The six pre-sets include: Standard – for crisp, vivid images that don’t require post-processing Portrait – optimises colour tone and saturation and weakens sharpening to achieve attractive skin tones Landscape – for punchier greens and blues with stronger sharpening to give a crisp edge to mountain, tree and building outlines Neutral – ideal for post-processing Faithful – adjusts colour to match the subject colour when shot under a colour temperature of 5200K Monochrome – for black and white shooting with a range of filter effects (yellow, orange, red and green) and toning effects (sepia, blue, purple and green). The User Defined Picture Style can be used to store up to three customised pre-sets, or any of the pre-sets available for download from Canon’s web site at http://www.canon.co.jp/Imaging/pictu...ile/index.html. Software Digital Photo Professional Software Digital Photo Professional software provides high speed, high quality processing of lossless RAW images. Processing with Digital Photo Professional allows real-time display and immediate application of image adjustments, giving control over RAW image variables such as white balance, dynamic range, exposure compensation and colour tone. Images can be recorded in camera with sRGB or Adobe RGB colour space. Digital Photo Professional supports sRGB, Adobe RGB, ColorMatch RGB, Apple RGB and Wide Gamut RGB colour spaces. ICC (International Colour Consortium) profiles can be attached to TIFF or JPEG images when converted from RAW. This allows faithful reproduction of colours in software applications that support ICC profiles, such as Adobe Photoshop. For improved efficiency, a set of image adjustments can be saved as a recipe and applied. EOS Utility The latest version of EOS Utility provides essential support for Live View remote shooting, camera configuration and image transfers. Tightly integrated with Digital Photo Professional, EOS Utility can be configured to monitor ‘hot’ folders, automatically renaming and moving incoming images to a structured file system.

IanB 0 Posted January 27, 2008 Report Share Posted January 27, 2008 The 30/40D range have a higher iso range , processing photo's at the top range with minimal noise. Also faster shutter speeds as mentioned and I'm sure an actual physically larger cmos sensor. Quote Link to post Share on other sites
Event-foto 0 Posted February 15, 2008 Report Share Posted February 15, 2008 The build of the 450D is not as rugged as the 40D. The 450 is a plastic case To Quote - "Compact and lightweight Ergonomically designed for natural and intuitive handling, the EOS 450 is housed in a compact body that weighs in at just 475 grams." "40D - Magnesium alloy body" You gets what you pay for. Quote Link to post Share on other sites
IanB 0 Posted February 15, 2008 Report Share Posted February 15, 2008 Yes 40D is weatherproof too I think... I like the 40D, the 450D looks good value with the extra features especially live view similar to the 40D's. Quote Link to post Share on other sites
MikeTheDog 153 Posted February 15, 2008 Report Share Posted February 15, 2008 Camera's sure have come a long way in a short time!...Reading the spec',..it's amazing what them little slanty eyed feckers have come up with ...When I were a lad ...I took a Kodak Box Brownie on the school trip now we have camera's/video recorder/voice recorder in our mobile phones that are probably far more advanced than a PC.....Reminds me of a TV advert, "One day Thomas man shall land on the moon!"....
