Our Opinion
A few short months after having released the DiMAGE A1, Konica Minolta (these two manufacturers have combined their resources) has now rolled out the DiMAGE A2; a camera that continues the use of a solid magnesium alloy body with rubberized surfaces.
The A2 is a relatively large camera, comfortable to hold and with a large number of external controls and buttons that might appear a bit intimidating at first.

The camera design provides a large grip which affords a solid hold, and which is topped by the Shutter Release with a Front Control Dial — a wheel control — directly behind it.
Still further behind, positioned between the Front Control Dial and the Mode Dial, is a microphone that serves to capture sound with video clips, or a voice annotation to accompany a photo.

At left of these controls is a Data Panel which shows many of the current settings for the A2. The Display Panel is backlit, and lights up in green for approximately 5 seconds every time the shutter release is pressed halfway.

Two other buttons are aligned below the Data Panel:

controls the quantity of information displayed on the EVF (electronic viewfinder) or the monitor each time it is pressed:

  • basic image data (shooting mode, resolution and image size, metering mode, frame number and AF brackets or Flex focus point,
  • same as above but adds a real time histogram,
  • no overlaid information aside from the AF brackets/Flex focus point,
  • no superimposed data, live image only.

In playback, the button serves to change the quantity of information displayed on the screen, or to see thumbnails of the images on the memory card (4 or 9 per screen).


can have either one of two functions assigned in the menu: it can either serve to turn on the 2X digital zoom, or be used to magnify the centre of the frame to help focus the camera when manual focus is used. In addition, it can be used to engage image magnification in playback (up to 10.2X).

Shooting modes are selected with the Mode Dial, also on the top right of the camera. 10 modes are offered:

Usually the Auto Mode takes care of all camera settings and limits the type and number of settings that can be made by the user. This is not the case with the A2. The Auto mode is similar to the Program mode and even allows program shift, but with one exception: switching from the Auto mode to another mode resets any settings made while it was in use; unlike the Program mode.
Program allows the camera to select aperture and shutter speed. In additon, the user can select alternative combinations of aperture and shutter speed that would result in a similar exposure (Program Shift) simply by turning the Front Control Dial. Any settings made in the Program mode are recalled when the Mode Dial is returned to that position.
Aperture Priority provides control over the aperture range of the A2's lens ((f2.8, f3.2, f3.5, f4, f4.5, f5, f5.6, f6.3, f7.1, f8, f9, f10, f11), and apertures can be selected with either the Front or Rear Control dials.
Shutter Priority offers control over the entire range of shutter speeds of the A2, from 1/2000 second to 30 seconds.
Manual gives the user complete freedom to adjust apertures and shutter speeds. Apertures are selected with the Rear Control Dial, shutter speeds with the Front Control Dial. Over or Under exposures are indicated in red characters.
Portrait optimizes skin tones, and softens sharpness. A wide aperture is used to blur the background, an effect that becomes more pronounced if the zoom is used.
Sports prioritizes a fast shutter speed to freeze movement.
Sunset optimizes the colour saturation to capture warm tones.
Night Portrait uses a low shutter speed to capture the background and red-eye reduction flash to capture the subject in the foreground.
Memory Recall allows recalling any one of five distinct set of shooting preferences.
The back of the camera is taken up by the EVF and the monitor on the left, and therefore the controls are grouped on the right. Near the top are the Main Switch , and around it the Mode Switch. The Mode Switch serves to select Still Image capture, or Playback, or Movie mode. To the right of the Mode Switch is the Rear Control Dial which, like the Front Control Dial, serves to set a variety of parameters.
Below the Rear Control Dial is the AEL button:

By default, the AEL button maintains the metered exposure parameters when pressed in. However this can be modified in the camera's menu so that:

  • instead it locks the exposure when pressed once, and releases the settings when pressed a second time;
  • or locks the exposure parameters decided at the Spot meter point.

Accesses Exposure or Flash Compensation when pressed in while turning either the Front or Rear Control Dials. The Front Control Dial varies the exposure compensation, while the Rear Control Dial serve to set the Flash exposure compensation (±2 EV in 1/3 EV increments).
The Display Mode Switch is next, directly below the compensation button. The Switch controls:

Only the EVF is active.
Automatic selection of the EVF or the LCD monitor. Sensors to the right of the EVF's exit pupil detect when the user's eye is near the EVF and activates it.
Only the Monitor is active.

As always, the 4-direction controller is designed to navigate the menus of the A2, and the button at the centre serves to confirm selections. Some additional functions are available in playback, when a photo is displayed on the monitor:

  • The up arrow allows superimposing the shooting data and a histogram of the image.
  • The down arrow rotates the image on the display in 90° increments.
  • The centre button has an additional use in the Recording mode. Holding in the button for more than a second switches the AF system from a Wide Area AF to a Spot focus called Flex Point which can be displaced anywhere in the frame using the 4 arrows. Pressing the centre button once more returns the focus point to the centre, and holding a bit longer returns to the Wide Area system.

A row of 3 buttons complete the controls situated on the back of the DiMAGE A2:

Provides a Quick View of the last captured photo or video clip.

In Playback this button allows erasing one image at a time.
Calls up the menu.

The third button turns on or off the A2's Anti-Shake system which stabilizes the CCD, not the lens elements. When active the Anti-Shake button is lit green, and its symbol is displayed on the EVF or the Monitor in one of four colours that indicate its current state:

  • White: indicates that the system is currently inactive and that camera shake could affect the image sharpness.
  • Yellow: indicates that the system is active, but that the shutter speed is too low for the system to be effective.
  • Blue: indicates the Anti-Shake system is active.
  • Red: indicates that the Anti-Shake system is overheating because of ambient conditions. The system shuts down automatically and the camera must be allowed to cool.

The electronic viewfinder to of the DiMAGE A2 is the second major improvement (after the increase in resolution) in comparison to the A1. The EVF is composed of 922,000 pixels, a 640 x 480 display, and the image it produces is very detailed. Moreover, the display can be set to either one of two modes in the menu:

  • Quality 30 fps which yields a very high resolution VGA image.
  • Smooth 60 fps ideal for fast moving subjects but which uses a half VGA resolution (640 x 240).
The EVF can be tilted up to 90° upwards, and provides a diopter correction on the left side of the housing to adjust it to one's eyesight.

The 1.8 inch LCD monitor of the A2 is identical to the A1's. It can be tilted down 20° and up 90°, making it possible to view the screen when the camera is held overhead, or placed on or near the ground.
All the remaining external controls of the A2 are on the left side of the camera.

The Function Dial is near the top of the body and provides a quick and efficient way to set often needed settings without having to scroll through the menus. By turning the dial to the needed function, and pressing its centre button while rotating one of the Control Dials, the following options can be modified:
MSET serves to memorize up to 5 sets of camera settings which can be recalled later.
Custom can be used to access one of 6 functions (Image Size, Image Quality, Flash Mode, Colour Mode, or Depth of Field Preview to be instantly available when the Function Dial is set to this position. Assigning a specific function is done in the Setup menu (see the Interface and Software section of the review for an overview of all the options of the Setup menu).

Metering mode:

  • Averaging using 300 specific points in the frame.
  • Centre-Weighted.
  • Spot metering, either at the centre of the frame or where the focus point is.

Drive modes:

  • Single-frame advance: to capture a single image each time the shutter release button is pressed.
  • Bracketing: to capture a series of three images with a selectable variation in exposure, contrast, saturation, or colour.
  • Continuous Advance: allows capturing three images at 1.8 fps when the shutter release is held pressed in. Focus is established at the first frame, and the camera displays each frame post capture.
  • High-speed continuous advance: captures a series of three images at approximately 2.7 frames per second. Focus is fixed at the first image, and the monitor is turned off during the capture.
  • UHS (Ultra High Speed) continuous advance: captures multiple 640 X 480 size images at approximately 7 frames per second (a 1/30 sec minimum shutter speed is required.
  • Interval: allows capturing a series of images with at a specified time interval.
  • Interval and Time Lapse Movie: captures a series of 640 x 480 images at a preset interval which can then be played back at as a slow motion movie at 4 frames par second.
  • Self-Timer: engages the self timer (2 or 10 second delay).
White Balance: Auto, Daylight, Tungsten, Fluorescent, Cloudy, Shade, Flash, or up to 3 custom white balance settings.
To set the ISO sensitivity of the CCD: Auto (between 64 and 200 ISO), 64, 100, 200, 400 or 800 ISO.

The centre button of the Function Dial has an additional use. Holding it in while pressing the button superimposes a composition grid on the displays, or a scale.

A speaker is fitted directly below the Function Dial, next to a standard Flash Synch terminal that is covered by a screw-on cap. The flash synch terminal allows a studio or location flash system to be connected to the camera with a standard PC cord. The terminal is compatible with both centre positive (normal polarity) and centre negative (positive polarity) flash units with a voltage of 400V or lower.
Next comes the Digital Effects Controller. This control serves to adjust contrast, colour, and saturation:

Filter: When the A2 is set to capture colour images, the FIL setting can be used to warm or cool the image over 11 steps (0 or ±5 steps).

When the A2 is set to capture black and white image, the FIL control can tone the monochrome image in 11 steps, cycling from neutral to red, to green, to magenta, to blue and returning to normal.
Saturation: serves to increase or decrease colour saturation over ±5 steps.
Contrast: serves to increase or decrease image contrast over ±5 steps.

The last two external controls of the A2 are near the base of the camera: is the Custom White Balance button. Pointing the A2 at a white surface under ambient light while pressing the button sets the white balance for the specific lighting. The custom white balance can then be saved in any of 3 memories.

Finally, a slider switch serves to select the Focus Mode:
  • Single Shot AF,
  • Continuous AF,
  • Manual Focus the A2 can be manually focused using the focus ring on the lens barrel near the body, and the central part of the image can be enlarged on the monitor or EVF to assist in focusing.

The top of the DiMAGE A2 is fitted with a Minolta flash shoe, compatible with Minolta flash units 2500, 3600HS, 5600HS, Macro 1200 and 2400 with controller.

Third party Minolta-compatible flash units can also be used, but some restrictions may apply.

The DiMAGE A2, like the A1, offers an excellent ergonomic design. Doubtlessly, a fair amount of time must be invested in understanding and getting used to its numerous external controls, but with a bit of time, their logical and well though-out placement and functions make the task much easier than it appears to be at first.
