Nikon D50样片
送交者: 王福贵 2005年12月07日20:16:46 于 [五 味 斋] 发送悄悄话


Digital SLR's are quickly becoming the fastest moving segment of the digital camera market, this means more new digital SLR's, more competition and lower prices. The Nikon D50 is introduced as a more affordable and easier to use version of the D70 which was released just under fifteen months ago. Anyone who has seen or handled the D70 will immediately see a strong resemblance in the D50, it's only when you start to examine the camera in a little more detail that you notice the differences (we've detailed them below). Clearly the D50 is designed to compete with other affordable digital SLR's such as the Canon EOS 350D (Digital Rebel XT), Pentax *ist DS and Olympus E-300.

Differences between D50 and D70/D70s
Although quite similar in use and appearance there are some noteworthy differences between the D50 and D70, we have detailed all of the feature / specification differences in the table below. To summarize the most important; the D50 has improved auto focus especially in the area of motion tracking, it has a new auto AF mode (which automatically switches between single and continuous AF depending on the subject), it has a lower resolution metering sensor but that sensor is a newer generation than the one used in the D70 (and D70s) - spot metering circle is also larger, the maximum shutter speed is 1/4000 sec, continuous shooting is 2.5 fps, it has a better viewfinder eyecup, the LCD monitor has increased to 2.0" in size, the D50 takes SD cards (not CF), it's slightly smaller and lighter than the D70 and several features have been removed or simplified to make the camera easier to use.

The only key difference between the D50 and D70 from an image pipeline point of view is that the image processing algorithm has now been tweaked to improve rendition of highlight detail (to clip less and have a softer roll-off to the highlight). It's also worth noting that the D50's default color space mode is IIIa which is still sRGB but is described as being optimized for nature and landscape photographs, you can see the difference in the sample on this page of our D70 review.
