Konica Minolta Dynax 5D
The Konica Minolta Dynax 5D ( North America : Konica Minolta Maxxum 5D, Asia: Konica Minolta α-5 Digital and Konica Minolta α Sweet Digital, official model name: DG-5D ) is a digital single-lens reflex camera from the Dynax series from Konica Minolta .
The Dynax 5D , released in September 2005, is the third and last digital SLR camera developed by Konica Minolta and sold under its own name, after the RD-175 (1995) and the Dynax 7D . Like the Dynax 7D , the Dynax 5D also has an anti-shake system integrated into the housing . In terms of functionality, equipment and quality of the materials used, however, it is slightly reduced compared to the Dynax 7D . The Dynax 5D has little in common with the analogue namesake sister Dynax 5 , but like them it is more aimed at amateur photographers.
Technical details
The image sensor
The Dynax 5D as the Dynax 7D with a Sony RGB - CCD sensor with Bayer pattern and a 12 bit - A / D converter equipped, the color depth, thus amounts to 36 bits. The effective resolution is 6.1 million pixels (total number of pixels 6.3 million), the size of the chip 23.5 mm × 15.7 mm (corresponding to APS-C format).
The smaller sensor dimensions compared to the 35 mm format (24 mm × 36 mm) lead to a cropping of the lens used by the format factor 1.5 in relation to the 35 mm format. The image scale and angle of view of an 18 to 70 mm zoom lens on a Dynax 5D correspond to a 27 to 105 mm zoom lens on a 35mm camera .
The anti-shake system
The image stabilization system developed by Konica Minolta , in contrast to systems from other manufacturers, in which the correction is made in the lens, is based on a movement of the CCD chip (CCD shift) and is therefore independent of the lens used. This enables the use of a large number of lenses from other manufacturers without losing the image stabilization system. This system has already been used in compact cameras of the DiMAGE series and was also integrated into the Dynax 7D .
The anti-shake system (AS system) developed by Konica Minolta measures the direction of movement and the acceleration of the movement of the camera using two gyroscope sensors. From this data, the electronics calculate the correction movements with which the piezo elements move the CCD chip.
The seeker
In contrast to the Dynax 7D, which is equipped with a prism viewfinder, a mirror viewfinder (silver- mirrored roof viewfinder) was used in the Dynax 5D , while the image section is 95% identical in both models. The mirror finder is significantly cheaper and also lighter than prism finders, but the brightness is lower. The focusing screen has a spherical micro-honeycomb structure. The integrated diopter compensation can be set between −2.5 dpt and +1 dpt, and eye correction lenses are optionally available.
The multifunction display
Another difference to the Dynax 7D is the lower resolution of the LC display of 115,000 pixels; the Dynax 7D has 207,000 pixels. The screen diagonal of 6.3 cm (2.5 inches ) is unchanged. In addition to checking the images, the display also shows the camera settings. As is the case with most SLR cameras, it cannot be used as a viewfinder, as is the case with digital compact cameras.
The case
The housing of the Dynax 5D is made of black or silver-colored glass fiber reinforced plastic and not, like the Dynax 7D, of an aluminum - magnesium alloy. The grip areas are set off with non-slip rubber . The lens bayonet is made of metal.
The size of the camera body is 130.5 mm × 92.5 mm × 66.5 mm (W × H × D), the weight (without battery and storage medium) is 590 g. It is therefore significantly smaller and lighter than the Dynax 7D and, despite the integrated anti-shake system, not significantly heavier (sometimes even lighter) than cameras from competing manufacturers such as Nikon , Pentax and Olympus. The additional weight due to the 1500 mAh lithium-ion battery NP-400 is 85 g.
The storage media and formats
CompactFlash cards (type I and II) and microdrives are supported for storing the image data . SecureDigital and xD-Picture memory cards can also be used by using the appropriate adapters .
The images are saved in two different file formats:
- JPEG format: When using the JPEG format, images with a resolution of 3008 × 2000 pixels, 2256 × 1496 pixels or 1504 × 1000 pixels can be saved. You can choose between three compression levels.
- RAW format: In contrast to the widespread JPEG format, the image data in the RAW format is uncompressed with 12 bit color depth per channel and saved in maximum resolution without further post-processing by the camera software ( white balance , color saturation , contrast, etc.) . The images in raw data format are not suitable for file exchange due to their size (approx. 9 MB) and their incompatibility with many image viewing programs; however, they give the photographer more options for retrospectively designing his images on the computer. The Minolta RAW format has the file extension MRW and can be edited using the DiMAGE Master Lite software supplied and converted into common image formats. The professional image processing program Adobe Photoshop CS2 supports the MRW format only with the Camera RAW 3.3 update.
In addition, images can also be saved in both formats simultaneously; the resolution of the JPEG file can be selected.
The lenses
Thanks to the Minolta A bayonet, all Minolta AF lenses can be used on the Dynax 5D . The AF-DT lenses developed by Konica Minolta specifically for digital photography are designed for the smaller sensor format and can be attached to a Minolta 35mm camera, but the smaller image circle of the AF-DT lenses leads to a ring-shaped shadowing at the edge of the 35mm negative. Due to the high black content of this ring, the camera increases the exposure time in the automatic modes and thus overexposed images result. In compensation, the dimensioning of the AF-DT lenses for the smaller sensor format enables a more compact design. The same applies to the Di II ( Tamron ) and DC lenses ( Sigma ) from so-called third-party manufacturers. The takeover of the A-bayonet from Sony resulted in a number of new DT lenses. However, some lenses were only changed externally and not technically and thus adapted to the Sony Alpha system.

The flash technique
In the Dynax 5D two flash metering modes are available: The conventional TTL flash metering and the specially from Minolta developed ADI -Blitzmessung (Advanced Distance Integration) . The ADI flash measurement is only possible in combination with the lenses of the (D) series. When using other lenses, filter attachments or close-up lenses , the ADI flash measurement cannot be used and the TTL flash measurement must be selected. The same applies to the use of a wide-angle diffuser on the Minolta program flash unit , for indirect flashes or flash units from other manufacturers.
The built-in flip- up flash with the guide number 12 achieves flash illumination up to a lens focal length of 18 mm. Although the hot shoe is compatible with older flash units, only the Konica Minolta program flash units 5600HS (D), 3600HS (D) and 2400 (D) can be used with their full functionality on the Dynax 5D . Automatic exposure metering is not supported with flash units of the HS, Xi and i series. These are always fired with full flash output, unless they are set manually.
Minolta's exit from the photo industry
On January 19, 2006, Minolta announced the decision to concentrate entirely on the office equipment segment ( copiers , printers , scanners , etc.). The production of Minolta cameras is discontinued. The know-how is sold to Sony . In the summer of 2006, Sony presented the first digital SLR camera with the Minolta- A bayonet. It is a revised version of the Dynax 5D, which appeared on the market a short time later under the name α 100 ( Alpha 100 ).
Problems and error patterns
On February 3, 2007, Konica Minolta announced the existence of a serial error in the Dynax 7D and 5D models, which could result in the first picture (s) being black or severely underexposed (bluish tint) after long pauses. This error, known in the relevant forums under the name "Error 58", was repaired by Konica Minolta free of charge until the end of 2010, even after the warranty / guarantee had expired.
