主题：【重要通告】关于数码相机的初始感觉 -- 赢政
家园 尼康镜头s have warmer color tone so I like 尼康 cameras more, well, just becaus of personal taste.
家园 两家人不说一家话........ 佳能和尼康孰优孰劣争了也没结果，只要色友们拍的顺手，用的开心就好。关于F80的AF对焦精度么，手头没别的机器，没法比啊，早些时候的相关技术测试显示F80的对焦精确、快速。至于与其他机器的差别，我这样的菜鸟，肉眼凡胎，实在难以分辨。兄台若有心得还望赐教，也好让我这菜鸟开开眼，长长见识。
家园 好说好说，测AF精度这个事儿还是两家通用的 自己找把尺子，有毫米刻度的，成四十五度角前后方向放在几米开外。当然要能看到那尺子上的刻度咯。
然后准备三角架，良好的光线，把你的镜头打到最大光圈，分别用各个对焦点对准尺子上某一个刻度（称之为零刻度好了）进行拍摄。
然后检验拍下来的照片，因为是最大光圈，所以应该只有焦点附近是清晰的，其他部分就该模糊化了；看看这样照下来的照片，最清楚的部分，是不是你对焦时候的零刻度，就知道你的相机AF功能是不是有偏移了。
如果有偏移，你可以看到清晰部分的中心，不是在你所试图对准的零刻度，而是偏前或偏后一些，这就说明你的相机配这个镜头，出现了跑焦现象。偏前多少，偏后多少，都要记下来。然后换一个对焦点进行下一组测试；
你要有N个镜头，分别测试之。
据我所知D100和俺们家的10D，是最有可能出现跑焦现象的。
俺们佳能家，出现跑焦现象，可以拿着机身和镜头去找佳能，让他给咱免费调节；
不知道你们N家如何了~~~~~
家园 老兄啊，您就直接说用景深测试AF精度不就可以了吗........ D100采用的是F80的对焦系统，而F80的对焦精度是目前市面上所有AF相机中最精确的，速度也是最快的。
至于佳能的售后服务可能尼康没有，也许是我没听说，但无论如何还是羡慕佳能用户有这样周到的服务。总的来说，市面上用佳能的多，尼康的少，看看各种重要场合的记者用的清一色都是佳能机器就知道了，还是兄台有战略眼光啊，在下眼拙，目光短浅，兄台见笑了。
家园 大意不得大意不得 众所周知，D100和10D是DSLR开始普及的先驱。
当初都以为这两款机器不会也不该有对焦问题，结果偏偏是他们两兄弟，都被先后报告发生了问题。
原因还真就是因为他们使用了FSLR原装的对焦模块......
我们知道，DSLR的传感器相当于FSLR的135胶片，但在D100和10D上，传感器的大小要远比135胶片小不少，所以要发生焦距转换的。现在普遍认为，这个过程不是想象中那么简单的，所以才会出现同一台机身配不同镜头就会有聚焦有的清楚有的不准的现象，也才需要一个一个镜头地侧试才行。
到了最近，佳能家也好，尼康家也罢，都为DSLR重新专门设计对焦模块了，以避免这样的问题。
家园 Welcome to the digital world! 专业人士对D100的评价
Conclusion - Pros（优点）
Excellent resolution, good colour, tonal balance tends to be more 'contrasty'
Superb 3D matrix metering
Selection of output colour space (however JPEG files not tagged correctly)
Very nice ergonomics, good feel, balance and control layout
Wide selection of ISO sensitivities, all the way up to ISO 6400 equiv.
Low noise in JPEG images up to ISO 800, more noise visible in RAW converted images
Very fast operation, instant power up and no delays in menus or playback
Excellent auto focus, works well even in low light, AF assist lamp
Great selection of white balance options, fine tuneable white balance
Great flexibility, custom control over self-timer, meter power off times etc.
Nice 'loupe' style playback magnification
Good suite of software included (Nikon Acquire, View, View Editor, Camera Control)
RAW mode option, included 'Nikon View Editor' provides rudimentary RAW conversion
Remote capture software for studio setups
Full Nikon F mount lens compatible (better with D and G type lenses)
IBM Microdrive compatible
Built as a Digital SLR from the ground up
Easy to use, integrated digital / photographic controls and displays
Gridlines in viewfinder display
Top panel LCD illuminated
Nice LCD monitor cover included
Custom functions to control camera operation
Excellent battery life, light weight and small batteries
Lighter than the competition (D60, S2 Pro)
Superb value for money
Conclusion - Cons（缺点）
Lacking in-camera sharpening leads to 'soft' looking images (to keep noise down?)
Internal / external D-TTL flash metering problem
Higher noise levels from images converted from RAW through Nikon Capture 3
Nikon View Editor RAW conversion has limited functionality (NC3 required for full control)
JPEG files not tagged with correct colour profile when color mode II selected
No onboard PC Sync flash socket (req. optional adapter)
Awkward ISO selection on mode dial
Firewire would have been nice
Compressed RAW mode is almost unusable (40+ seconds to store)
Viewfinder view is smaller than 'higher end' D-SLR's
Overall conclusion（总评）
Nikon started the current D-SLR revolution. Yes, we saw digital SLR's before the D1 but that camera in particular was a breakthrough. It broke down price barriers and announced the fact that the traditional camera manufacturers were serious about producing their own digital SLR's. No longer tied to Kodak's digital back Nikon's designers produced a serious camera in a small(er), more robust body, excellent image quality and at a price which turned the D-SLR world on its head.
Since then Nikon has built on the D1 design with the D1x and D1H, but at the same time Canon decided it could go one better and introduced the EOS-D30 at the end of 2000 pushing price levels even lower and just teetering on the brink of the lucrative 'prosumer' end of the market. D-SLR's were coming to the masses.
So here we are, in 2002 with no less than four new high resolution digital SLR's, the first three of which are now making their way into end users hands. The most amazing thing is that we're looking at six megapixel digital SLR's at or around the US$2,000 mark. Pretty stunning when you consider Kodak were selling six megapixel D-SLR's for $16,000 as recently as August 2000.
Nikon's D100 was a response to the Canon EOS-D30, and obviously had to include a resolution hike knowing where the market was heading this year (six megapixels). Nikon's designers once more should take a lot of credit for producing a superbly well designed camera. Ergonomics, balance and control layout are excellent, the D100 feels both professional enough to be used on the most important days, yet small and light enough to be taken out on the most casual outing. Build and finish quality are second to none, you really are getting $2000 worth of camera.
Performance is also very good, power up times are instant, this means the camera will always be ready for your shot, menus and playback feel snappy and there's never really a time you find yourself waiting for the camera. Continuous shooting performance is good if not quite as good as the EOS-D60's double buffer (but we're really splitting hairs here).
The D100's feature set is also excellent, the provision of selectable colour space shows that Nikon takes the D100 very seriously, despite the price level this camera can be used by almost any type of user. Custom functions provide control over almost every camera feature, you can select a self-timer of 2, 5, 10 or 20 seconds, enable mirror anti-shock, enable or disable noise reduction, change the EV step level or even change how long the meter display stays on. There's plenty here for the shutterbug.
Image quality is also excellent, good colour and metering, nice tonal balance (if sometimes a little 'contrasty', this can be modified using the tone setting). I found the camera's internal sharpening to be too much on the soft side, this left some images looking soft at 100% view, a quick check against an equivalent RAW shot shows what the camera is capable of. This may be the only weakness in what is otherwise an excellent camera, very well built and offering superb value for money.
Highly Recommended
So which one should I buy? A question I get asked several times a day, and I wouldn't like to say. In a new addition to my reviews (after the amount of feedback I normally get) I've added a link to a specific forum in which you can discuss the review or ask me specific questions which I've not answered in these pages.
