细细里

Conclusion - Pros      

• Excellent detail and resolution  (especially in raw mode)
• Lovely new LCD screen - the 3:2 format really makes a difference.
• Capable, flexible AF system in both phase-detection and live view modes
• High-spec video mode, including  external microphone jack
• Highly intuitive operation, refined ergonomics
• Fast and responsive operation (although shooting in raw mode slows things down)
• Very reliable metering and white balance in most shooting situations
• Decent build quality for the price - no creaks
• Highlight Tone Priority works well, in both raw and JPEG mode.
• Excellent battery life for its class
• Acceptable - although not outstanding - image quality at highest ISO settings.
• Excellent supplied software suite - DPP is one of the best bundled raw converters around

       Conclusion - Cons      

• Auto Lighting Optimizer's effect is subtle to the point of being unnoticeable
• No rear control dial (as found on higher-end Canon bodies)
• Entry-level ergonomics won't suit everyone (the EOS 50D and 7D just feel nicer)
• No in-camera raw conversion option
• Slightly soft JPEG output at default settings (but this is far from unusual)
• Chroma noise takes a fairly big chunk out of resolution at ISO 12800 (but better than the 500D)
• AF assist strobe can be annoying

            Overall conclusion      As I mentioned in the introduction to this review, Canon has pulled out all the stops with the EOS 550D, and has delivered the most highly specified Rebel-series DSLR we've ever seen. In practice, the camera does not disappoint, and in all respects it gives excellent performance, at least matching but in most  cases bettering the best of the competition. Given that the competition includes cameras like the excellent Pentax K-x, and Nikon D5000 - both of which also feature video capture - this is high praise indeed.
      After extended use of the EOS 550D, one of the most impressive things about the camera is its consistency. The 550D can be relied upon in almost any environment to deliver pleasant, well-exposed images, and although it obviously can't match the likes of the EOS 1D Mark IV or the Nikon D3S at its highest ISO setting of 12800, it is measurably better than its predecessor the EOS 500D, despite a hike in resolution. This is impressive in itself, but the fact that the 550D also brings an improved video mode (equal in the essential points to the current best video-enabled DSLRs on the market) will come as music to the ears of Canon users looking either to upgrade from a 1000D or 450D, or to 7D users looking for a (relatively) inexpensive backup camera.
      It is these photographers, who already own a higher-end DSLR, that I think will really appreciate the 550D. Despite the entry-level ergonomics, and the inclusion of beginner-friendly features like Creative Auto mode, the 550D is actually closer to the EOS 7D in terms of specification. Crucially, it delivers this specification at a fraction of the size and weight, not to mention a lower price.
      Image Quality
      As you can see from the shooting that we've done for this test, the EOS 550D sets new standards for resolution in its class. In favorable conditions, in raw mode, it is clear that the 550D can unequivocally resolve more detail than an equivalent camera with 12 or 14 million pixels. Resolution in JPEG mode is lower than RAW, as we would expect, but at a pixel level, the difference should not concern most users. Unfortunately, however, the high pixel count of the 550D's CMOS sensor is something of a double-edged sword. Whilst it means that in optimal conditions, with a high quality lens attached, detail resolution is superb, it can also mean that when viewed at 100% on screen, images taken with cheaper, lower quality optics (including the bundled 'kit' option 18-55mm) look distinctly sub-par. It's an obvious point - higher resolution sensors make higher demands on lenses - but it is one which is easily overlooked in the race to put higher and higher pixel counts into low-end and enthusiast DSLRs.
      The unavoidable fact is that to get the most out of the 550D's sensor you really need to pair it with Canon's better lenses, which is a considerable investment. Arguably, this is academic for most enthusiast photographers, since most of the time digital images are either admired onscreen or in small (sub-A4) prints. Of course if this is how you primarily view your images (and if we're honest, for most of us it is), it could be argued that packing 18 million pixels is somewhat unnecessary in the first place.
      That said, the bottom line here is that the EOS 550D offers excellent image quality in a range of different conditions, including exceptionally low light, thanks to its usable ISO 12800 setting. Image quality is equal or better than its predecessor the EOS 500D, and not noticeably inferior to the considerably more expensive EOS 7D. The 550D's video capability is excellent too.
            Handling      The EOS 550D is the latest product in a long line of Rebel-series DSLRs which all share basically the same design intent - to make the camera's various advanced features as easy to use, and as easy to understand as possible. As such, it represents not a revolutionary ergonomic advance, but rather a slight refinement of a proven basic design. The handling differences between the 550D and 500D are very minor, and are a consequence mostly of the new, larger LCD screen, but the handling experience of both cameras is to all intents and purposes identical.
      The 550D doesn't provide a flawless handling experience though, and we do have some criticisms. The buttons on the rear are rather flat and close together, which makes it easy to mash them by accident, and very hard to press them accurately if your hands are cold/gloved/large. The general feel of the camera is plastic, and although far from flimsy, it doesn't have the reassuring heft of the EOS 50D or 7D. We wouldn't necessarily expect it to, but it is a shame that a camera with so much more to offer than the EOS 1000D (and at a considerably higher price) should have such similar build quality.
      It is also a shame that the 550D doesn't share the EOS 7D's stills/video shooting switch. This switch goes a long way to solving the problem of integrating video into a stills camera without the function feeling 'bolted on' and the fact that the EOS 550D - which is aimed at a less sophisticated audience - doesn't have it is frankly a little bizarre. After all, in theory, it is lower end users who will be most used to shooting video on cameraphones and compact cameras, so why not make this feature as easy to use as possible?
      The final word      Despite our (very minor) complaints, the EOS 550D is a very satisfying camera, and certainly offers the most compelling feature set of any nominally 'entry level' DSLR that we've used. It isn't just about spec though - the 550D's refined handling and excellent supplied software suite should not be overlooked. Although it doesn't represent a huge improvement over the 500D, the changes that have been made are worthwhile, and well-implemented. An external mic socket, manual control and wide choice of resolutions and frame rates means that the 550D is worthy of consideration for serious video use, and when paired with a high quality lens, image quality is superb.
      With all this taken into account, it is hard not to recommend the EOS 550D. Quite simply, taken as a whole, it is the best camera of its class that we've ever seen, and one of those rare cameras that won't look out of date in a couple of years' time.

细细里

几个重点小结一下：

*在同档次竞争对手里面最好的画质 （这无疑是最重要的）
*在这种分辨率下，最好配好点的镜头（也就是说，套头不推荐，我这么理解，有钱，还是红圈吧）
*画质比7D不差多少，摄像功能非常优秀
*总之，是现在你能找到最好的入门级相机，而且，在几年内都可能不会过时，而这种相机是很少能遇到的

老大，你表笑话我

国内的测评我不看的，因为商业味太浓。

相机测评，我基本只看Dpreview，比较公正

游而生侠

这个机器，好像叫入门级的“旗舰”吧。
再说说老生常谈的话题。
关于器材。
分2个层面来谈，一是私费。购买力强的，啥都别说了，想买啥买啥，能用上用上，不能用，自己欣赏。“我有”。有个文章，说美国人哪怕工间休息打几分钟篮球，也全副武装，把自己打扮成NBA球员，姿态很好。所以，美军战损很低，比如，每到一处，哪怕停留半天，美国大兵也把掩体或者战壕按规定构筑得好好的。。。该2米深就2米深，不像很多国家的士兵偷懒，就挖个半米。。。所以，该买的器材全买上，也属于此类。哪怕是纯粹玩器材的。有错吗？没错。糟蹋器材吗，不糟蹋。
购买力不强的，购买相机不是小开销，要反复比较，精心采购。这样也好，按经济规律办事，没有必要为爱好，影响家庭财政，影响夫妻感情。又不是靠摄影养家糊口，器材够用就可以了，没必要超过自己的能力或者动血本去购买一大堆器材。硬是超级发烧、骨灰发烧，那没办法，还得鼓励。总之，器材，够用就要，切忌攀比。
二是公费购买。这类人，因为花的纳税人的钱，器材一般都是最顶级的，所有中国的报社、有关企事业单位的照相机，都是全世界最好的、最新的——只买贵的、不买对的，不象国外的自由摄影师，讲究投入产出比。但是这类人有个特性或者说有个优点吧：不炫耀、不攀比、而且很少谈论器材，因为器材来得容易，一个报告的事，或者是配给你的——自己都不需要去想。正因为如此，心思没放在器材上，放在拍摄上——给你最好的相机，不出东西怎么行，你得交差啊。我所知道的是，报社的很多摄影记者，对搞创作、参加比赛啥的，基本没精力顾及，每天完成发稿任务，就精疲力尽了。更别说谈器材、泡论坛了。
再说了，这些东西只有使用权，没有产权，谈了白谈。————所以，我记得有个专业的摄影论坛，大家亮骚——大炮，400的600的，就特别申明：公款购买人员勿进。大家玩属于自己的，你进来干嘛。所以啊，单位的越野车司机，是很少跟我们玩在一起的，有也不多——他们等同与报社的摄影记者

   意犹未尽，继续来，抛砖引玉
  不对之处，请大家批评指正

钟乳石

数码机发展到现在，大家都掌握了成熟的技术，相互间的差距已经很小了，如今的数码机的原理不作根本改变，是不会有上一台阶跨跃的，不要特别迷恋评测，评测只是个传说，自己拍的随手，拍出作品才是真的，老一点相机，用RAW格式拍，解出来不会比新机器差，现在拼得就是镜头群了。

分析得透彻！
偶有一去年进藏的朋友，人民日报社的，机身3个，镜头若干，大炮600，摄影器材带了半车，一路狂拍。
另一哥们有钱，LC200、BMW740各一辆，NIKON D3X小钢炮也一路猛拍。

玩摄影器材确实很重要，但不是绝对的，主要还是色技，技术提高了即使卡片机照样能出好片。

前提是RAW

很多兄弟基本不用RAW的，这个对相机的JPG压缩算法提出了很高的要求。

比如DP1的JPG出片质量被推崇，但佳能的JPG出片被很多人认为软，不如Nikon的锐，这个还是每个厂商的取向不一样。

还有就是像素，我当年差不多1W买的30D，像素只是现在550D的一半。在电脑上看无所谓，如果要放大片，像素多少是起决定作用的。

而且，数码的发展，总体说来，新的比旧的好。胶片可以留经典机器，数码我总是推荐最新的。

器材确实很重要，这是基础。

使用好器材就是本事了。

  先谈一个概念。
  什么叫专业相机？以我的浅薄认识，就是能满足恶劣条件下实用的相机，特点是坚固、扎实、耐用、可靠性高、适用性广。比如到南极快门能正常启动，一盆水下来照样工作等等。总之，就是在地球的极限状态下，不掉链子。这跟重型越野车的设计，是一个道理，艺术、产品，都是相同的嘛。
  专业相机，我只认2款，一是佳能，二是尼康。其他品牌，我没接触过，也不想了解，因为这2款相机，已经足够足够足够满足我的需要了。
   与专业相机有关的，我认为有这几个指标：连拍速度、快门寿命、降噪能力、电池耐用度等。。。。。有种说话，说专业相机的设计标准，是以满足体育摄影为目的——推而广之，连跳水都能连续抓拍下来，还有什么不能满足呢？
   搞懂了什么是专业相机，对我们摄影爱好者来说，就对选择相机有个清晰的认识了。先问自己：一、我想拍什么？二、我常去那里拍？三、我用什么器材拍？搞清楚这3点，想买的器材也就出来了。一般来说，一个机身，一个广角，一个中焦，一个长焦，就是最标准的配置了，基本可以满足各种需要。由此，有上述区间的变焦头：16—35、24-70、70-200，俗称3剑客，以此类推。

     我们在实践中可以得出经验，与其说机身重要，要不如说镜头最重要，我们可以得出这样一个结论：镜头的变化（比如镜片的材料）比机身慢，甚至没变化，因此，我们是不是树立这样一个观念：在有限的预算内，优先保证镜头质量，宁可相机是入门级，优先保证镜头能专业级或者准专业级。

这话绝对是中毒摄影准备烧器材者的正确思路

钟乳石

当感光体的分辨率大大超过镜头时，提高图像质量的主要因素就是镜头。现在当下就是这种情况。当以RAW格式拍摄时，基本都是一样的“素”材。你要什么德味、莱卡味等照片均可在后期修改。

细细里

再说几句。

除了有钱一步到位，或者公家配发的，掏自己腰包的烧友基本避免不了发烧的漫漫历程。我说的是烧友，就是一直，长时间会投入精力在这个领域的爱好者，而不是，我就需要一个简单工具的人。

在最开始，我们很难知道什么对我们是适合的，会很犹豫是否要买很贵的器材，所以，往往瞄准入门级。

然后，在不断的学习，吸毒过程中，器材更换开始了。。。。。。。

其实老游基本把准则说完了，拍什么，什么情况下拍。。。不过要回答这个问题，往往是一个刚开始的爱好者是很难回答的，多半要经过长时间的自我斗争。

还有，我一直告诉自己：干活和玩的东西可能不一样。干活需要的是工具，玩的东西，寄托了很多爱好和把玩的成分这里面。干活我一定用自动头，但是玩，我可以享受手动操作的那种感觉。就跟很多人还留着胶片机可能是一样的道理。

有钱，尽量买高素质的镜头，这个是最省钱的玩法。数码时代，机身的进步是高速的，镜头很慢，很慢。一些经典的头，买来如果很喜欢，就可以当做收藏了。

还是那句话：鼓励发烧和折腾（别是瞎折腾，比如甚至影响家里关系那种），折腾的乐趣，跟一开始上来就用大兔子是不一样的。

当银子叮噹响的时候就用狗头吧，当银子哗啦哗啦响时就用红圈吧！


用狗头拍不出好片片就骂狗头吧，用红圈头拍不出好片片就骂自己吧！

其实。。。无知者无畏挺好。。。。
看完这篇，我就上550D。。。。上三个镜头------有上述区间的变焦头：16—35、24-70、70-200，俗称3剑客，以此类推。
虽然。。我还没有弄明白，什么叫景深，什么叫光圈。。。。
我是老游毒害的。。。各位记得给我报仇。。。
