AS-System
CCD-Shift Anti-Shake System Anti Shake is compatible with almost every lens* • The cameras CCD is shifted in the X and Y dimension to compensate for the camera shaking • Two angular velocity sensors detect the camera shake
Compensation: • 2 - 3 steps in shutter speed with fixed focus lens
User benefits: • Shutter speed bracketing in max. 3 stages. Even beginners can take pictures in the telephoto range under low lighting. • Helps avoid failure shots so anyone can shoot with confidence. • ISO speed can be reduced to decrease noise
* Except the Macro 3x-1x zoom lens 1.7-2.8 and special lenses
• Macro photos without using a tripod
AS-System
CCDS-Shift Anti-Shake System The accuracy of shake correction requires exact focal length information. For achieving precise control with almost every Konica Minolta lens the Dynax 7D performs the following controls: • The Dynax 7D has data about every AF lens produced by Konica Minolta in its ROM • For SSM and D–series lenses the focal length is provided by the interceded distance encoder. • For and non- D–series lenses the focal length is provided through the amount of AF-coupler movement.
AS-System
SIDM (Smooth Impact Drive Mechanism) To compensate camera shake, the movement of the CCD has to be extremely fast and precise. The unique Konica Minolta SDIM is not only fast and precise but is also very small. The SIDM is a linear-drive acuter which moves the CCD bonded to the drive shaft. The piezoelectric element has the characteristic of expanding when voltage is applied. When the voltage is cut off, the piezoelectric element abruptly contracts, but the moving body remains.

CCDS-Shift Anti-Shake System Marco: Anti-Shake works against shaking in the x- and y-axis. As result of the small depth of field, the shaking in the z-axis has a big effect on macro photography. Anti Shake works in macro photography but the performance is decreased.

AS-System
Frequency Range Optical Image Stabilisation works only for high frequencies. Anti Shake works also for low frequencies (1 to 2 Hz). This is the reason Anti Shake is able to compensate camera shaking with wide angle shots.
The frequency range has been shifted to high frequencies from DiMAGE A1/A2. Low frequencies will still be compensated.

Comparison CCD Shift / Optical Image Stabilisation One part of the optical system can be shifted to eliminate the influence of the camera shake. The camera shake is detected by gyro sensors. The amount of lens shift is calculated in the lens. The optical image stabilization can compensate between one and two, or two and three speed steps (depending on the lens).

Auto focus
Phase Detection AF System The phase detection system can control the seamless lens drive almost up to the focus position since it detects simultaneously direction and the amount of lens movement.
AF-Sensor Dedicated Auto Focus CCD CCD
Auto focus
Comparison Video-AF/Phase Detection The Video AF determinates the focus point by calculating the contrast of the image provided by the CCD. The video AF requires multiple processes. The speed of a Video AF is slower than the speed of a phase detections AF.

9 Areas 8 Lines The Dynax 7D is equipped with a 9 area and 8 lines AF sensor. The AF sensors are placed close to each other within the wide focus frame to provide flexible compensation when shooting stationary and moving subjects.
Auto focus
Focus Modes Single-shot AF Mode (S) When the shutter-release button is pressed halfway down in singleshot AF mode, the AF system focuses and locks on the subject. Direct Manual Focus (DMF) is available after focus is locked.
Continuous AF mode (C) With the shutter release button pressed halfway down, the AF system keeps focusing according to the movement of the subject and focus-lock does not engage even when the subject stops.
Auto focus
Automatic AF Mode (AF-A) The control of AF-A is selectable through two modes in the menu; According to the movement of the subject, the camera automatically switches between Continuous AF and Single-shot AF modes (default settings). -When the focus is locked in the one shot AF mode, the AF system switches automatically to DMF (Direct Manual Focus). Focusing continues while the subject moves. With still subjects, focus is locked when the shutter-release button is pressed halfway down.
Auto focus
Predictive Focus Control The Dynax 7D achieves the high performance of the predictive focus control in speed and accuracy with the powerful AF motor, the simultaneous lens drive during the mirror-up movement and the improved AF algorithm. The system has been conventionally used on our 35 mm film SLR cameras which includes the Dynax 7.
Auto focus
Subject Tracking Indication The Dynax 7D emits the red LED to indicate the selected local focus area in the viewfinder. User benefits: • Instantly focuses where you want it
When continuous AF is active, the LED indication moves in the viewfinder screen following the moving subject. The LED is emitted to the selected local focus area intermittently so that the user can easily identify this selected area.

D-series Lens
Lens with built-in distance encoder. (AF lens drive is controlled on body)
AF coupler remains engaged for AF drive by the built-in motor of the body. Distance information is obtained by the built-in distance encoder of the lens.
Non D-series Lens
Lens without built-in distance encoder
AF coupler remains engaged for AF drive by the built-in motor of the body. Distance information is obtained by the built-in distance encoder of the body.
AE Metering
Comparison AE Metering DiMAGE A2/Dynax 7D The exposure control of the SLRtype digital camera with built-in lens is carried out by the output from the CCD. The dedicated sensor (SPC) for metering is incorporated in the viewfinder because the shutter remains closed except during the shutter release.
Metering Sensor (SPC) 14 segments
CCD 265 segments
User benefits: • Measuring free of CCD errors like noise or smear
AE Metering
14-Segment Honeycomb Pattern/CenterWeighted/Spot The Dynax 7D is equipped with a 14-segment honeycomb metering, which has been used for conventional 35 mm film SLR cameras. To provide precise exposure for the main subject, the frame is divided into 14 zones in the form of a honeycomb pattern. The data is determined whether the scene has normal or black lighting, is a portrait or landscape etc. This analysis sets the optimum exposure.
AE Metering
Other than 14-segment honeycomb-pattern metering the following are also available:
Centre-Weighted Average Metering: The metering sensitivity is concentrated in the centre area but the surrounding area is also taken into account.
Spot Metering: Sensitivity is concentrated in the centre of the circle area for the accurate metering of specific areas of your subject.

Flash
Flash Metering Mode
analogue SLR
digital SLR
The Dynax 7D employs two flash metering modes
ADI flash Metering Mode: Distance information from the AF system and that from a pre-flash exposure are used for exposure calculation.
Pre-flash TTL Metering Mode: The exposure is calculated with a pre-flash only.
Flash sensor
Metering Sensor (SPC)
Because the CCD does not reflect the light of the flash like a film ,the flash metering is not possible by using a Flash sensor. The flash metering of a digital camera needs a pre-flash which is measured by the AE-sensor.
Flash
Pre-flash TTL Metering Mode The pre-flash is fired the 14-segment honeycomb pattern cell meters the refection from the subject. The result is fed back for the calculation of flash power level. This method is basically the same as the one used in the existing SLR-type digital camera with built-in lens. The integral function is not provided by the AE sensor as it is primarily developed for metering the ambient light. Therefore to calculate the flash power level of the main burst without the integral function, a flat-pulse flash is necessary.

Handling
Zone matching The camera is set to under exposure before recording to read the CCD output in the highlighted area that cannot be obtained otherwise. After that, the tone curve is raised to correct the brightness settings to the standard exposure level. Camera setting with Zone matching: • ISO 125 • Natural sRGB • Contrast adjustment is disabled User benefits: • Emphasizing the tone reproduction in the highlight area, the noise slightly increases.
Handling
Zone matching With this function, the camera is once set to over exposure before recording to develop the tone reproduction capacity in the lowbrightness area to obtain the image data. After that, the tone curve is depressed to correct the brightness settings to the standard exposure level.
User benefits: • Minimizing the occurrence of noise, the image is easily lost highlight details
