Press Release:
Outstanding speed and resolution for the discerning photographer: the EOS 50D
Amstelveen, The Netherlands, 26 August 2008: Canon today strengthens its EOS range with the addition of a powerful new digital SLR: the EOS 50D. With a 15.1 Megapixel CMOS sensor, 6.3 frames per second shooting and Canon’s latest DIGIC 4 image processor, the EOS 50D delivers unparalleled speed and resolution at a price point that is unique in today’s market.
Outstanding, clean images
A newly designed 15.1 Megapixel CMOS sensor delivers ultra-detailed, low-noise images – ideal for large-scale reproduction or creative cropping. New manufacturing processes, plus redesigned photo diodes and microlenses, extend the light gathering capabilities of the sensor – allowing more pixels to be fitted on the CMOS sensor without compromising image quality. These changes ensure improved high ISO performance and low noise. High-speed, low light shooting is enabled by ISO levels of 3200, expandable to an ultra-sensitive 12800.
The EOS Integrated Cleaning System – including the improved Self Cleaning Sensor Unit with a new fluorine coating – increases protection of image quality by helping to reduce, repel and remove unwanted dust from the sensor. Stubborn particles can be removed automatically in post-production with Dust Delete Data and Canon’s included Digital Photo Professional software.
Rapid-fire performance
Canon’s new DIGIC 4 processor is fast enough to allow up to 6.3fps continuous shooting, in bursts of up to 90 JPEGs with a UDMA card. Used with Canon’s wide area AF system, which locks onto subjects with 9 individual cross type sensors, stunning action sequences can be captured – even in low-light conditions. This makes the EOS 50D particularly suited to sports and wildlife shooting.
DIGIC 4 works with the CMOS sensor to deliver 14-bit image processing, for smooth gradation and natural-looking colours – as well as ensuring ultra-fast startup times and near-instant image review after shooting.
See everything
A new 3.0” Clear View VGA LCD provides extra-large and wide angle-of-view image review, with plenty of clarity for accurate focus checks in playback. By switching to Live View mode – which displays a real-time image on the LCD – photographers can enjoy simplified shooting from awkward angles, or connect to a PC for remote shooting. Live Mode now offers three ways to auto focus: Quick AF, Live AF, and new Face Detection Live AF, which optimizes focus based on faces detected in the frame – for fast, spontaneous portraiture.
Control and ease
The famously intuitive EOS menu system includes a new Quick Control screen, for instant access to the most commonly-changed settings. A new Creative Auto mode offers automatic focus and exposure – while still allowing creative ‘tweaks’ to settings such as background sharpness.
“For advanced amateurs and semi-professionals – or professionals looking for a powerful backup model – the EOS 50D stands alone,” said Mogens Jensen, Head of Canon Consumer Imaging, Europe. “No other camera in this price bracket offers a comparable combination of speed and image quality.”
Technologies Explained
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.
DIGIC
Image data captured by the CMOS sensor is processed by Canon’s purpose-built DIGIC image processors before being written to the camera's memory card. DIGIC technology uses advanced image processing algorithms to ensure precise, natural colours, accurate white balance, and advanced noise reduction. Ultra-fast processing speeds result in highly responsive camera operation and near-instant start-up times.
DIGIC chips work with a high speed DDR-SDRAM image buffer – reading, processing, compressing and writing image data fast enough to keep the buffer clear during long continuous shooting bursts. And because DIGIC integrates all key processing functions, power consumption is kept to a minimum.
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, including a special fluorine coating, 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 are:
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).
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, noise reduction and colour tone – plus the ability to view Auto Focus points on an image. The Lens Aberration correction tool allows precise correction of different types of distortion caused by certain cameras. 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. Users can also tag their images with EXIF data, including copyright information.
Picture Style Editor
Picture Style Editor allows users to create individual Picture Styles that fit with their personal requirements. Each Picture Style contains detailed information on how specific colours should be represented within an image. Once new Picture Styles have been created, they can be uploaded directly into the camera and applied to JPEG or RAW images. When working with RAW files in DPP, both personal Picture Styles and the 6 predetermined Picture Styles can all be adjusted.

Press Release:
Outstanding speed and resolution for the discerning photographer: the EOS 50D
Amstelveen, The Netherlands, 26 August 2008: Canon today strengthens its EOS range with the addition of a powerful new digital SLR: the EOS 50D. With a 15.1 Megapixel CMOS sensor, 6.3 frames per second shooting and Canon’s latest DIGIC 4 image processor, the EOS 50D delivers unparalleled speed and resolution at a price point that is unique in today’s market.
Outstanding, clean images
A newly designed 15.1 Megapixel CMOS sensor delivers ultra-detailed, low-noise images – ideal for large-scale reproduction or creative cropping. New manufacturing processes, plus redesigned photo diodes and microlenses, extend the light gathering capabilities of the sensor – allowing more pixels to be fitted on the CMOS sensor without compromising image quality. These changes ensure improved high ISO performance and low noise. High-speed, low light shooting is enabled by ISO levels of 3200, expandable to an ultra-sensitive 12800.
The EOS Integrated Cleaning System – including the improved Self Cleaning Sensor Unit with a new fluorine coating – increases protection of image quality by helping to reduce, repel and remove unwanted dust from the sensor. Stubborn particles can be removed automatically in post-production with Dust Delete Data and Canon’s included Digital Photo Professional software.
Rapid-fire performance
Canon’s new DIGIC 4 processor is fast enough to allow up to 6.3fps continuous shooting, in bursts of up to 90 JPEGs with a UDMA card. Used with Canon’s wide area AF system, which locks onto subjects with 9 individual cross type sensors, stunning action sequences can be captured – even in low-light conditions. This makes the EOS 50D particularly suited to sports and wildlife shooting.
DIGIC 4 works with the CMOS sensor to deliver 14-bit image processing, for smooth gradation and natural-looking colours – as well as ensuring ultra-fast startup times and near-instant image review after shooting.
See everything
A new 3.0” Clear View VGA LCD provides extra-large and wide angle-of-view image review, with plenty of clarity for accurate focus checks in playback. By switching to Live View mode – which displays a real-time image on the LCD – photographers can enjoy simplified shooting from awkward angles, or connect to a PC for remote shooting. Live Mode now offers three ways to auto focus: Quick AF, Live AF, and new Face Detection Live AF, which optimizes focus based on faces detected in the frame – for fast, spontaneous portraiture.
Control and ease
The famously intuitive EOS menu system includes a new Quick Control screen, for instant access to the most commonly-changed settings. A new Creative Auto mode offers automatic focus and exposure – while still allowing creative ‘tweaks’ to settings such as background sharpness.
“For advanced amateurs and semi-professionals – or professionals looking for a powerful backup model – the EOS 50D stands alone,” said Mogens Jensen, Head of Canon Consumer Imaging, Europe. “No other camera in this price bracket offers a comparable combination of speed and image quality.”
Technologies Explained
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.
DIGIC
Image data captured by the CMOS sensor is processed by Canon’s purpose-built DIGIC image processors before being written to the camera's memory card. DIGIC technology uses advanced image processing algorithms to ensure precise, natural colours, accurate white balance, and advanced noise reduction. Ultra-fast processing speeds result in highly responsive camera operation and near-instant start-up times.
DIGIC chips work with a high speed DDR-SDRAM image buffer – reading, processing, compressing and writing image data fast enough to keep the buffer clear during long continuous shooting bursts. And because DIGIC integrates all key processing functions, power consumption is kept to a minimum.
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, including a special fluorine coating, 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 are:
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).
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, noise reduction and colour tone – plus the ability to view Auto Focus points on an image. The Lens Aberration correction tool allows precise correction of different types of distortion caused by certain cameras. 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. Users can also tag their images with EXIF data, including copyright information.
Picture Style Editor
Picture Style Editor allows users to create individual Picture Styles that fit with their personal requirements. Each Picture Style contains detailed information on how specific colours should be represented within an image. Once new Picture Styles have been created, they can be uploaded directly into the camera and applied to JPEG or RAW images. When working with RAW files in DPP, both personal Picture Styles and the 6 predetermined Picture Styles can all be adjusted.

The Lens Aberration correction tool allows precise correction of different types of distortion caused by certain cameras. 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. Users can also tag their images with EXIF data, including copyright information.
Picture Style Editor
Picture Style Editor allows users to create individual Picture Styles that fit with their personal requirements. Each Picture Style contains detailed information on how specific colours should be represented within an image. Once new Picture Styles have been created, they can be uploaded directly into the camera and applied to JPEG or RAW images. When working with RAW files in DPP, both personal Picture Styles and the 6 predetermined Picture Styles can all be adjusted.

40被人骂，还是一样的卖的好，
50应该还是一样会大卖。

另外，操作界面和闪光灯也有待提高，一味拉高像素迟早要到尽头的。

像当年 我买个10d，还要13800，现在50d才9000多，性能差了不止多少倍
不过我同意天气预报，在对焦和闪光灯方面，好好改进一下
但是，我肯定还是要换一个50d的，我那个时间太久了。。。虽然只拍了9000多张，寿命还早

这个过了吧。在AF上，确切的说，在高档机上，Canon 和 Nikon 各有千秋，主要是在侧重面。佳能偏运动和新闻，主攻tracking，1系列的45点就是专门为这个搞的，功能和设定都极强。Nikon主要侧重肖像，综合，所以准确，尤其是低光下是口碑极好的。但速度就差一点，当然这和Nikon的镜头AF有关。可以这么说，在1950 -1987 这段时间内，Nikon是遥遥领先的，尤其是佳能换EF卡口不兼容时，怨声载道。但事实上，佳能做对了，EF卡口没有了旧技术的包袱，在电子技术日新月异的今天，USM, IS 技术再加上佳能在1980年就把家当赌在Digital Sensor 上了，就是在本世纪初6个年头，就几乎把两者的地位和市场（高档和专业用户）倒了各个。那时Nikon还在嘲笑Canon，吹自己的F卡口兼容如何，现在到头来不也是学佳能打搞 AFS 和 VR。那个所谓的兼容也是一笔糊涂账，后面一长串的Exception，且每个机身（中低档）都不同。比到软件，DPP是佳能自己搞的，而且是免费的。NX可是要买的，而且这个东西主要还不是Nikon的，User Interface and Engine是别人的，另外，这二个软件定位都不同，佳能的侧重是Raw Conversion and Pre-processing，时要求用Photoshop做后续的。Nikon 更本是作为 Photoshop Replacement 的，两者没有可比性。
扯那么陈年老账干什么？而且我前提就是在说目前阶段的机身，镜头没在这里讨论。
45点AF最早是在3上弄出来，眼控实践证明并不够快速和可靠就被阉割掉搭载到1上面，然后这45点AF就小打小闹折腾到现在。在马三上也就19个十字对焦点。泥坑现在已经提升到51点AF，15个十字点，但最关键是顶级D3，中高档的D700，APSC幅面的D300都装备了这么强的AF系统。说明这套系统的成本和性能都达到了一个非常平衡和强悍的位置。到这份上了，你还说C的AF系统好吗？？
AE和闪光系统的差异看来你也是看得到和承认的。
DPP是送，NX的顶级机身上也是送。C可从来没说DPP需要继续后续制作，而且它也有很独特的算法，解C家自己的RAW时出的色彩和锐化都比用别的软件解码来的好。但本身自己在界面、功能上这些软件方面的缺陷实在不是用“可比性”就能掩盖对比NX的缺陷。

像素增大当然有好处，135幅面机器比画质，现在还是1DS III最领先。但我个人对在APSC幅面上达到1500w像素很怀疑，我对比1D II和40D的RAW，40D的噪点就已经不可忽视了。按目前科技和成本，那么小画幅上实现那么大像素，肯定要妥协某些性能。具体等到手后深入玩玩再分享心得。
我觉得这个还是C的销售策略，其它方面没什么可说了，就猛吹自己像素高，这个是广大消费者最直接会明白的。你说一大堆AF，AE那些深入分析，别说消费者了，很多资深爱好者也会糊涂。

镜头的好坏，尤其是镜头内置马达，直接关系到AF，当然可以谈。我试过D2x和D2h的AF,Servo的Tracking 不这么样，可能不太熟悉专门的设定把，但尼康历来不太重视Servo（和佳能比起来）。作为一套顶级的AF系统，是需要时间来完善的。尼康一直在换AF Module，从一个侧面来说，是在不断摸索。等到它不再走马观花的换，应该也差不多了。现在还为时太早，让它过了一二代再说。至于尼康的中档机上的AF，那是因为历来它的Sensor太差，实在拿不出手，所以只能在AF 和AE 和界面上动脑筋，而佳能可以用差的 AF 等照样卖。现在尼康的Sensor 追上来，佳能就用高像素来回击。我估计佳能以前在这方面留了一手，因为在Sensor方面领先很大，不太可能一下子就被人追上。
至于Flash,我本身不这么用，550EX一直没换。真要拍人的话，Studio Strobe就可以了。个人在用 Elinchrom RX和它的Light Modifier 系列，和Profoto 差不多，但 Broncolor 太贵，玩不起。

D90以后估计非专业级都得要有短片功能，这是第一台。按我经验：千万不能买。
反而50D可能会成为C门不带DV功能的非专业机的最后一台，可以买。
所谓超高像素，你可以选择的，你可以选择低像素模式来拍。但很多时候，光线好或者主体小，冲大幅。。。像素高了好处有很多。

干扰就是会少
降低像素来拍画面滑很多，只是分辩率下降了。
尼康特别一点，以前有一种剪切降低像素实现高速连拍的方法，D2X吧，跟这个不同。
不对吧，泥坑某几种高档那种减低像素高速连拍是直接把画面裁了，比如D2X和D2，在取景屏里就有阴影把裁切部分遮住的。
我想请教你这么肯定会减少，那意思是假能在生成低分辨率图像时，没有减低减低图像取景范围，就是整块CMOS的成像范围都用上了，但是图像文件体积小了，那是把成像点取舍了一部分？还是机内软件给压缩了？这个算法给大家介绍一下？？这也是我一直闹不明白的地方。
而且，为了减少噪点和干扰就要减少像素，那厂家做那么高像素的机器有意义吗？把像素降到什么地步，才能达到一个噪点和画质的平衡？比如，我想用40D，拍出30D一样分辨率的片子，但噪点也要和30D一样，该降到多少？？

Studio Flash 中文应该是摄影灯，确切说是冷摄影灯，主要是区别于 Continous Lighting 或者说热摄影灯。摄影灯按电源区分主要有交流和直流。直流一般是一个 Portable Generator Pack (控制和电源） 再加上 Lamp Head （闪光灯头）。交流又有细分 Pack System （类似直流，由一个交流的控制和电源，加上几个闪光灯头）和 Compact (闪光灯头和电源控制在一起）。用摄影灯的关键是 Light Shaping （控制和调节光源）。摄影灯一般完全是手控，用相机的 Sync Port （同步通道）来控制。高级的用无线电指令，一般都用 Pocket Wizard 或 Elinchrom Sky-Port，曝光还是单独测光，调节。
一个好的摄影灯和一个差的摄影灯价格可以相差几倍到十几倍以上。主要的区分是 Color Consistency Between Shots （稳定的灯光温差），Unique And Complete Set of Light Shaping Modifiers （独特和齐全的调控光附件），Flexible Control and Durable Design （多功能调节和耐用牢固的设计）。
灯光温差指的是色光，用K （凯尔文）表示（类似于显示屏的色差调节）。好的灯拍照时的温差在50K以内，包括连拍，Stop Down （减小输出）等，差的要在几百度凯尔文。这在专业制作中是致命的。一个只要调一次就可以Apply to the Batch (做为一组的标准），另一个要每张调节，而且很困难。
在室内用摄影灯，特别讲究的是 Light Control（调光） ，防止 Light Polution （光源重叠，造成局部光效失调），Power (强度），Direction (方向），Hard Light （热光源，又称点光源），Soft Light （折散光，又称面光源）是靠不同的调控光附件来完成。一个好的系列，一般都有齐全和独特的调控光附件。像我用的 Elinchrom 就有一个注册的 Beauty Light ，本身就是一个6尺大的 Octo Box （八角散光灯盒），但和一般的不同，灯是装在盒内，而且是面对着反光面，最大限度折散光，再加上大，可以弄成一个巨大的面光源。
在控制上，微调是很有帮助的。我用的 Elinchrom Style RX 1200 有6 Stops Digital Control (6倍光电子调节），从37 W/s 到 1200 W/s，每个倍数可以微调在1/10 Stop。这样就不用为了光控而冒着摔倒的危险搬动光架。比如换一个Grid，或者Gel Sheet，光的比例会变，有微调功能的不用移动，直接切换即可。一般的头没有细调只能搬了。

摄影灯一般完全是手控，用相机的 Sync Port （同步通道）来控制
说的就是这个问题，只要有同步插口，任何相机都是这样用，和机身程序没关啊

对啊，那Nikon的 AE 对我来说就不这么重要了。:$ :$

不对吧，泥坑某几种高档那种减低像素高速连拍是直接把画面裁了，比如D2X和D2，在取景屏里就有阴影把裁切部分遮住的。
我想请教你这么肯定会减少，那意思是假能在生成低分辨率图像时，没有减低减低图像取景范围，就是整块CMOS的成像范围都用上了，但是图像文件体积小了，那是把成像点取舍了一部分？还是机内软件给压缩了？这个算法给大家介绍一下？？这也是我一直闹不明白的地方。
而且，为了减少噪点和干扰就要减少像素，那厂家做那么高像素的机器有意义吗？把像素降到什么地步，才能达到一个噪点和画质的平衡？比如，我想用40D，拍出30D一样分辨率的片子，但噪点也要和30D一样，该降到多少？？
是啊，关于尼康D你说的没什么不同。我说的就是剪切的方式来降低像素，也就是文件小了处理时间快了。它的标称就是XX万像素时，连拍可以达到多少张。它特殊，所以我先把它剔除。
关于其它高像素机用低像素格式来拍，比如佳能这几部机，它是把整块（有效的，与原来面积一样的CMOS的成像范围都用上了。几个像素点按比例合成一个大像素点了。
另外，分辩率是和像素有关的。像素越高，分辩率就越高。
所以40D要和30D一样的分辩率，设成同样像素就可以了。
由于它们都是APSC，像素一样时，单从这个指标看噪点也应一样，但是40D的控噪有其它改进，所以有无法比较的地方。比如一个处量器是DIGIC III, 一个是DIGIC II.

不敢苟同
我这样理解，如果对同样景物用同样镜头不同像素的相机拍摄后，生成同样尺寸的文件，这样很容易理解是像素越高分辨率就越高。因为要是输出文件尺寸定了，你像素点越细密，当然分辨率越高。可是很明显，不同像素相机生成的文件大小是不同的。因为像素点大小不同了，像素间的间距，按我手头的资料，也是不同。这样分辨率和像素的关系绝对不会是个线性的正比关系。而且像素过分紧密必然带来更重的互相干扰，或其它技术细节问题。
所以回过头看这个问题，40D和30D，就算设到同样像素，但由于像素排列距离，算法（处理器）等因素，分辨率也不可能是一样的。
另外我在DPP或PS的输出时都遇到，不同像素，但同样dpi的情况。基本上DPP都是默认300dpi的输出，照您的说法，像素大了，分辨率自然也高，输出的dpi又代表什么呢？

呵，不苟同也得苟同。
因为分辩率的定义不是可以争论的话题，就是和像素成正比。
你说的输出DPI只反映输出精度，都用300DPI，这种情况下，低像素肯定比高像素的画面小。如果输出设备允许的话，1500万和500万都可以用同样的DPI，但一个画面很大，一个很小。
不必不爽，你的问题已经是我在这里见过最深的了。

DPI 和图像的分辨一点关系都没有，和像素大小也无关。这是一个输出密度的相对比例而已，虚的东西。DPI 是英语（Dot Per Inch）的缩写，意思是每英寸里输出多少个点。比如送上网的照片一般是72dpi，普通数码像片的大型印刷是300dpi，自己的墨水打印机是360dpi，专业的数码印刷是252dpi，等等。用dpi可以准确地计算出终端像片打印的大小，和像素无关。说穿了，就是输出打印的点相对于英寸的大小。
比如，一张1800x1200的照片，输出到300dpi的打印机，那它的像片尺寸是6“ x 4"。输出到252dpi的打印机，那就是7“ x 5" 了。即使是你设错dpi，打印机还是会用自己的dpi来输出。
分辨率是输入的密度，在固定的距离可以用多少点来描述固定的范围。这和dpi完全是两码事。
