Nikon D70
The Nikon D70 and D70s are the revised version of Digital SLR ( DSLR) camera with 6.1 - megapixel image sensor in the Japanese manufacturer Nikon DX format.
General
In the spring of 2004, the Nikon D70 was brought as a model of entry-level class on the market. In the spring of 2005, she has been revised and designated as D70s, whose production ended in September 2006.
At the time of market entry, the market segment of SLR beginners class was dominated by the competitors with the Canon EOS 300D. The success was based on a previously unbeaten price - performance ratio for DSLR cameras. To make up for lost ground here, a higher quality camera at a similar price was necessary, without having to compete with the professional digital SLRs from a private home. This balancing act managed to Nikon and the D70 was able to successfully position itself in the market.
The D70 has the 1959 introduced Nikon F mount for interchangeable lenses, and can use all appropriate lenses, which can be expected on older lenses with restrictions. For example, the camera can not make metering in conjunction with manual lenses (MF lenses). MF lenses can therefore only in full manual mode, but are not used when set to one of the automatic programs.
Through the opposite mm film (36 × 24 mm) reduced sensor is a form factor gives (also called crop factor ) of 1.5. In order to address the specific circumstances of the digital SLR, Nikon created a new lens - class DX - Nikkor lenses. However, these can make only limited use because of the smaller image circle on the small screen cameras.
The camera body was also sold as a kit with the zoom lens AF-S DX Nikkor 18-70 mm / 3.5-4.5 G ED, either in addition to the AF Nikkor 70-300 mm/4-5, 6 G. Only in Europe, there was a further, particularly affordable option, the kit with the particular really for small format cameras AF Nikkor 28-80 mm / 3.3 to 5.6 G.
Technology
The 6- megapixel sensor allows images of up to 3039 × 2014 pixels. The images can either be lossy JPEG with 8 -bit color depth with a maximum of 3008 × 2000 pixels or stored without loss as a proprietary raw data format with 12 bit color depth ( it uses its own Nikon NEF format). A combination of simultaneous storage takes of RAW and JPEG is also possible, while JPEG is greatly compressed.
The exposure time can be set from 1/8000 to 30 seconds in 55 steps, a long exposure (bulb ) is also available. The camera can also be triggered via an optional IR remote control. The maximum exposure using bulb mode by remote shutter is half an hour, right on the camera, it is only limited by the power supply.
The D70 has an adjustable sensitivity from ISO 200 to 1600 in both automatic as well as manual operation. There are several exposure modes are available: Program AE, aperture priority, shutter priority and manual exposure. There are also a number of subject programs: Full Auto, Portrait, Landscape, Close-up (macro ), Sports and Night Scene.
To check the recordings and to display the setup menu, a color LCD screen located on the back of the camera. This monitor can, as with many other SLR cameras can not be used to image search, because the folding mirror covers the sensor. However, this brings the advantage of a lesser heating of the sensor and resulting lower noise. Furthermore, the energy consumption of the camera thereby decreases significantly, Nikon is for the lithium - ion battery to a capacity of more than 2500 images. With auto focus, exposure measurements, playback and flash but values around 500 shots are realistic. It was not until the newer models ( D5000, D5100, D90, D300, D300s, D700, D3, D3x, but not the D3000 ), it is possible with the so-called Live View to look at the subject beforehand on the monitor.
There is a second, black and white, can be illuminated LCD screen on the top of the camera. It is used for clear display of the selected exposure mode, shutter speed, aperture, battery status, remaining recordings and similar information. Next it can be used for various settings such as exposure and flash compensation.
The camera also has a fold out flash and a hot shoe for external flash devices, along with an exceptionally fast flash sync speed of 1/ 500 seconds is offered. Located on the front plus a white AF-assist light.
To save the recordings is a CompactFlash card slot is available, which can also accommodate a Microdrive. The transmission of the image data to the computer via a USB port (type mini-B). Two standards are available: Mass storage ( allows the connection as a USB mass storage ) or PTP. The transmission rate complies with the USB 1.1 standard ( approximately 1 MB / s). For large memory card is therefore a separate compact flash card reader with USB 2.0 port is recommended. The camera supports the FAT32 file system on the CF memory card. Other file systems are not supported.
At extremely high shutter speeds (1/ 8000 s ), it may in dark areas come to a magenta cast, which increases to the right image edge. In practice, the problem does however not noticeable.
Successor D70s
The Nikon D70s was introduced in April 2005 as a successor to the D70. Maintaining the product D70 clearly suggests that the camera has been improved only in details. Data such as image resolution, speed of image processing, etc., remained unchanged. Only a larger screen and a connection for a wired remote release them visually different from its predecessor. Furthermore, the USB 2.0 standard - only supported with USB 2.0 full speed, the same data transfer rate offers as a USB 1.1 port ( up to 12 MBit / s or 1.5 MB / s). The improved menu navigation and optimization during AF can be obtained via firmware update for the predecessor.
