Even beginners can take pictures in the • 2 - 3 steps in shutter speed with telephoto range under low lighting. fixed focus lens • 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.

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

The camera shake is detected by gyro sensors. The amount of lens shift is calculated in the lens. without Stabilisation The optical image stabilization can compensate between one and two, or two and three speed steps (depending on the lens).

The Computing video AF requires multiple processes. The speed of a Video AF Motor is slower than the speed of a phase drive detections AF. AF value Close-up Auto focus 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 single- shot 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.
