Sony Alpha 100

The Sony α100 (DSLR -A100 ) was the first model in the series after Sony's acquisition of the Alpha system ( the SLR system around the A-mount ) Konica Minolta in the spring of 2006. The camera was on a press conference on June 5, 2006 presented in Marrakesh to the world and replaced on 5 January 2008 by its successor, Sony α200 dedicated (DSLR -A200 ).

The camera follows on from the Minolta Dynax series and is to be seen as the direct successor of the Dynax 5D, which clearly manifests itself in the appearance, handling, and in the underlying technology. So it is not surprising that that has been proven yet developed α100 Konica Minolta, show how an analysis of the firmware and the Konica Minolta code numbers " 2187 " in the service manual of the camera.

Sony took aim with this camera both beginners from the digital SLR market, as well as transfer passengers from analog photography. The α100 has a CCD image sensor in APS -C size ( 23.6 x 15.8 mm/28, 4 mm diagonal) with 10.2 megapixels of the Nikon D200 is basically the same.

The α100 can be operated both with Compact Flash cards, and with Sony's Memory Sticks. Since the camera has only one Compact Flash slot, Sony delivers with an appropriate adapter for the Memory Stick. Usually have fast CF cards compared to Sony memory sticks a speed advantage.

Technical Features

  • Eye-Start
  • Built contrast enhancer (Dynamic Range Optimizer)
  • Sensor Cleaning function to protect against contamination of the image sensor
  • Ability to infrared images ( transparent IR cut filter)

Lenses

All lenses can be used with the already introduced in 1985 still of Minolta A-mount without restrictions from a few exceptions.

Exceptions:

  • Minolta AF Reflex 500mm f8 (only the central AF sensor used )
  • Minolta AF -1 × 3 × Macro Zoom (no image stabilizer)
  • Some lenses from other manufacturers require chip upgrades to be properly recognized by the camera

Flashes

Flash can be used for the fully automatic flash control only when they are digitally compatible. These include the Minolta flash units in HS ( D) series and the Sony flash units of HVL -AM series. An existing ADI- ability of a flash unit is a more secure recognition feature for suitability in conjunction with the Alpha 100, but there are also some flash units that do not offer support FDI, but are still suitable for digital signals. These include the macro flash controller MFC -1000 for the ring flash and twin flash. The Sony Alpha 100 no longer supports the "classic" TTL metering of the film or sensor plane during exposure (TTL - OTF), as it is supported by virtually all analog Minolta Dynax cameras but uses a pre-flash for TTL flash metering ( TTL preflash aka P -TTL). Alternatively, it can also work with ( ADI flash control).

If a flash unit is not suitable for digital, flash is always fired at full power, which almost always leads to a severe overexposure; In extreme cases, the picture is even completely white.

If you want to be photographed with a non- digital -compatible flash unit, there are two options:

For both options, but it must be borne in mind that ambient light is not compensated, as is the case with TTL flash control, ie in strong light should have a larger f-number will be tried.
