Comparing the results from the Nikon D50 digital SLR with the Nikon D70s and the Canon Rebel XT, a number of conclusions can be made.
In our opinion, the Nikon D50 provides the most consistent and "best" straight out of camera results. The in-camera processing that occurs in the Nikon D50, in terms of sharpening and tone adjustments, produces images that are very pleasing to the eye when viewed straight out of the
camera. Ideal for users who want to go directly to print without having to worry about software post processing in a computer.
The Canon Digital Rebel XT comes in a close second, however, the Rebel XT by default applies less in camera sharpening, which has a tendancy to make the images
look a little softer. We did notice that even after post processing, the Canon Rebel XT images did not look as sharp as those from the Nikon D50, indicating that Nikon's new AF-S DX 18-55mm f/3.5-5.6G ED lens is a bit sharper than the Canon EF-S lens that comes in the Rebel XT kit. Nevertheless, the
Canon Rebel XT produces very good image quality in its own right.
In comparison, the images from the Nikon D70s have a tendancy to look a little flat and softer than those from the Nikon D50, when viewed straight out of the camera. Nikon has adopted a much more conservative approach to
in-camera processing with the Nikon D70s, realizing that there are certain disadvantages as opposed to proper post processing with external software applications, such as Nikon Capture or Adobe Photoshop.
As can be seen in the sample images above, the Nikon D50 produces images that are
very pleasing out of the box. When compared with the Nikon D70s image that has been post processed, however, you can see that there are blown highlight details in the Nikon D50 image that are still well maintained in the Nikon D70s shot. We suspect that the intended users of the Nikon D50 will find
that the advantage of being able to have very good image quality out of camera by simply using Auto settings, will outweight the negatives as mentioned.
Applying a slight unsharp mask and levels adjustment in Photoshop to the Nikon D70s "Landscape Mode" image, produces results that
outperforms both the Nikon D50 and the Canon Digital Rebel XT with their respective kit lenses. To be fair, the Nikon D70s comes bundled with a superior (and higher priced) lens, the AF-S DX 18-70mm f3/5-5.6G IF-ED Nikkor zoom, so the results should not be surprising.
With respect to
the 1600 ISO noise comparison, it can be seen that the Nikon D50 image is cleaner compared to the Canon Rebel XT depending on the colour channel. The Nikon D70s images at 1600 ISO are noisier than both the other models.
We feel that this is as a result of less in camera high ISO noise
reduction being applied in the Nikon D70s, as well as the fact that both the Nikon D50 and the Canon Rebel XT feature a different sensor design compared to the Nikon D70s. If you are going to cover indoor events and rock concerts, at higher ISO settings the Nikon D50 might just be the answer.
With respect to the Auto White Balance (AWB) setting, the Nikon D50 produces slightly warmer tones compared to the Digital Rebel XT and the Nikon D70s. All three cameras did a pretty good job when set to AWB in our tests, however, nothing beats setting white balance based on manual presets
if possible.
Bottom line, if you are looking for very good image quality overall and a user friendly camera system, you can not go wrong with either the Nikon D50 or the Canon Rebel XT DSLR kit package.
If you have a preference for Canon, for those that are planning to
use the camera for more advanced applications you might want to take a closer look at some of Canon's step up zoom lenses with the Rebel XT, and as a better option due to improved performance and overall durability, the popular Canon EOS 20D DSLR.
Likewise, for advanced amateurs and
those with professional applications who are looking to buy a Nikon, and want the creative control that post processing offers and desire the absolute best output in comparison, in our view there is simply no doubt, seriously consider the Nikon D70s kit with Nikon's AF-S DX 18-70mm f/3.5-4.5G IF-ED
lens. Otherwise, in our opinion, the Nikon D50 kit package looks like a great choice
Внимательно читаем вопрос : кто сравнивал 20d с d70(s) в полевых условиях в RAW. iso 100 есть у кэнона, и насколько она лучше iso200 никона по шумам и ДД?
Тот жу dpreview и kenrockwell обсравнивали эти тушки. Но! Это все в жпег. А это вата, а не сравнение.
Хочется в RAW с последующей обработкой в разных конвертерах и анализ ДД и шума. Просто, например где гарантия, что во внутрикамерном жпеге не стоит легкий d-lighting и шумодавчик?
Кто че найдет, ссыльните.
Не надо сходить с ума. Сравнение 20d и 70-ки ничего не даст. Все очень субъективно.В разных световых условиях камеры будут работать по-разному. Сравнивать надо качество (не только техническое, а и сюжетное) полученных фото. Вот где простор для приложения рук и головы.
