Sigma SD9 Review

Drive Mode Dial
Camera is powered off, any images still in the buffer will continue to be written out to the Compact Flash card. The top status LCD will show 'CF' to indicate that the Compact Flash card is still active.
Camera shoots in single drive mode, one depression of the shutter release results in one frame taken (assuming AF locks).
Camera shoots in continuous drive mode, camera shoots continuously while shutter release is held down as long as their is buffer space. This equates to approximately 1.9 fps at full resolution for up to 6 frames. If the buffer fills the camera will take the next shot when buffer space is available.
|Ten second self-timer
After depressing the shutter release the camera will beep for ten seconds before taking the exposure. Countdown is displayed on the top status panel.
|Two second self-timer
After depressing the shutter release the camera will beep for two seconds before taking the exposure. Countdown is displayed on the top status panel.
|Mirror lockup exposure
After depressing the shutter release the mirror is raised, release and then a gentle half-press of the shutter release will take the final exposure. This allows you to reduce vibration transmitted through the camera body by the mirror when taking long exposures or macros. It would have been nice to have a combined Mirror lockup and two second self-timer option.
After turning to this mode you can set the auto bracketing step to 0.5, 1.0, 1.5, 2.0, 2.5 or 3.0 EV. Turn back to a normal drive mode to take the automatically bracketed exposures. Use continuous drive mode and it will stop after the three bracketed exposures have been taken.
Hold button and rotate command dial to select metering mode:
Press once to change remote control channel (1-3). Press again to enable / disable the camera beep.
|Auto Focus mode
Hold button and rotate command dial to select auto focus mode:
Single Servo AF (S)
Continuous Servo AF (C)
Hold button and rotate command dial to select image resolution, this results in smaller RAW files but obviously less resolution recorded:
2268 x 1512 (HI)
1512 x 1008 (MED)
1134 x 756 (LOW)
Hold button and rotate command dial to select ISO sensitivity:

Exposure Mode Dial
There are four exposure modes available on the SD9 which can be quickly selected by turning the exposure mode dial.
Program Auto Exposure (Shiftable)
Aperture Priority Auto Exposure
Shutter Priority Auto Exposure
|M||Full Manual Exposure
In this mode you select the aperture and the shutter speed from any combination of the above (plus Bulb for shutter speed, apertures limited by the lens used). Half-press the shutter release and the meter on the viewfinder status bar and top LCD will reflect the exposure level compared to the calculated ideal exposure, if it's outside of +/- 3 EV the indicator bar will blink.
Press and hold this button then half-press the shutter release to lock the exposure. The exposure can be locked for a single or multiple shots.
Hold button and rotate the command dial to set an exposure compensation level. Compensation is available in half stop (0.5 EV) steps from -3 EV to +3 EV.
It's a pity that shutter speed / aperture and exposure compensation can only be selected in half stop steps, most other digital SLR's provide third stop steps which can provide that little bit of additional control.
