原帖由 细细里 于 2010-8-26 10:05 发表 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.

总的结论正如我在这次审查简介中提到,佳能已经退出了所有的佳能EOS 550D停止,并已交付了最具特色的反叛系列单反相机,我们见过。在实践中,相机也不会令人失望,并在所有方面它给优良的性能,至少配套完善,但在大多数情况下是最好的竞争。鉴于竞争包括像宾得Kx公司的出色相机,和尼康D5000 - 两者都还具有视频捕获 - 这确实是很高的评价。
经过佳能EOS 550D,以及对相机最令人印象深刻的事情之一是它的一致性长时间使用。该550D可以依赖于几乎任何环境,提供舒适,良好的暴露图片,虽然它显然无法匹配其最高的ISO 12800环境的佳能EOS维马克IV或尼康D3s喜欢,它是可衡量比其前任更佳能EOS 500D型,尽管在第一个加息。这本身是令人印象深刻,但事实是,550D也带来了改进的视频模式(以最佳的视频功能目前市场上的数码单反相机的基本点等于)会因为音乐的佳能用户的耳朵寻找要么升级从1000D或者450D,或7D的用户对一个(相对)便宜的备份照相机看。
正是这些摄影师,谁已经拥有一个更高端的单反相机,我觉得真的会欣赏550D。尽管入门级人机工程学,以及诸如创意自动模式初学者友好的功能在内,550D,其实更接近佳能EOS 7D条在规格方面。重要的是,它提供了在一个大小和重量,更不用提一个较低的价格的一小部分本规范。
图像质量
正如你可以看到从我们已经做了这个测试拍摄,佳能EOS 550D套在其决议类的新标准。在有利条件下,在原始模式下,它显然,550D可以明确地解决了一个多相当于相机详细的12或14万像素。在JPEG模式下分辨率是比生低,因为我们所期望的,但在像素级,差异不应该最关注的用户。但不幸的是,该550D的CMOS传感器的高像素数是一个双刃剑的东西。虽然这意味着,在最佳条件下,具有高品质的附加镜头,详细的解决方案是一流的,它也可以指在屏幕上时,100%效果,图像采取更便宜,质量较低光学(包括捆绑的'包'选项18 - 55毫米)看起来明显低于平均水平。这是一个明显的一点 - 更高分辨率的传感器就镜头的更高的要求 - 但它是一个很容易被忽视了在比赛中并提出更高的低端和高像素数码单反相机爱好者的罪名。
不可避免的事实是,获得了550D的传感器最出你真的需要搭配佳能的好镜头,这是一个相当大的投资。可以说,这是大多数摄影爱好者的学术,因为当时的数字图像,也大部分是屏幕上欣赏或小(分A4号)打印。当然,如果这是你首先查看您的图像(如果我们是诚实的我们来说,这是大多数),它可以说是包装1800万像素有些不必要摆在首位。
不过,这里的底线是,在EOS 550D提供在不同的条件范围,包括特别优秀的低光图像质量,其可用的ISO 12800环境表示感谢。图像质量等于或超过其前身佳能EOS 500D型好,并没有明显逊于相当昂贵的Eos 7D的。在550D的视频能力也非常好。
处理的EOS 550D是一个叛乱系列数码单反相机的所有份额基本上是相同的设计意图长线的最新产品 - 使易于使用相机的各种先进的功能,而且易于理解的可能。因此,它代表的不是一个革命性的人体工学的进步,而是一种经过验证的基本设计稍有改进。 550D和500D型之间的差异的处理都非常小,而且大多是新的,更大的液晶屏幕的后果,但是这两款相机的处理经验,是所有意图和目的相同。
该550D没有提供一个完美的操作经验,但是,我们也有一些批评。在后面的按钮都比较平坦,紧靠在一起,这使得它易于混搭意外他们,他们很难准确地按如果你的手冷/手套/大。相机的一般感觉是塑料的,虽然远离脆弱,它没有对佳能EOS 7D的安慰或30d的分量。我们不一定会指望它,但它是一个耻辱,一个有这么多事情莫过于佳能EOS 1000D(和相当高的价格相机)应该有这种类似的建设质量。
这也是一个遗憾,550D不同意在EOS 7D的的静态图片/视频拍摄开关。此开关走一段漫长的道路,以解决融入一个剧照相机功能没有感觉'闩上'和事实,即佳能EOS 550D - 这是一个不太成熟观众为对象 - 它是没有问题坦诚视频小奇怪。毕竟,在理论上,它是低端用户谁是最会用拍照手机拍摄的视频和小型相机,那么为什么不使这个feature一样容易使用的可能吗?
尽管我们的(非常轻微)投诉的最后一句话,在EOS 550D相机是一个非常令人满意的,当然最引人注目的特点提供任何名义上'入门级'数码单反,我们已经使用一套。它不仅是对规范虽然 - 在550D的精制处理和提供优秀的软件套件,不应忽视。虽然这并不代表比500D型巨大的改善,已取得的变化是值得的,和良好的执行。外部麦克风插口,手动控制和帧速率的决议和广泛的选择意味着550D是值得认真考虑的视频使用,在与高品质的镜头搭配,图像质量极好。
随着这一切考虑,很难不建议在EOS 550D。很简单,作为一个整体,它是同类产品中,我们见过的最好的照相机,摄像机和罕见的,不会看在几年的时间,情侣过时之一。 |
