Pentax K20D Review
Top of camera controls (left)
On the top left of the camera we have the mode dial (to select exposure mode), the metering mode lever and the exposure bracketing button (hold and turn the front dial to enable / select number of frames, rear dial to select exposure steps).
In the mode descriptions below the we talk about the default function of the front and rear dials, for P, Sv, Tv and Av modes these can be changed via the custom menu, as can the function of the green button in M mode.
Green mode (Auto)
|TAv||Shutter and Aperture Priority
The second unique-to-Pentax mode is the 'Shutter and Aperture Priority' mode, you select both the shutter speed (front dial) and aperture (rear dial) and the camera calculates the appropriate ISO sensitivity.
A dedicated Bulb mode, select the aperture using the rear dial and the shutter will remain open for the amount of time you hold the shutter release button or remote. Obviously ideally suited to use with a wired remote.
Designed only to be used with a flash. This mode simply selects the flash x-sync shutter speed, which is 1/180 sec, you can select the aperture using the rear dial.
Allows the retrieval of a previously saved exposure mode setup, in any of the above exposure modes simply select the 'USER' option from the Setup menu to save for retrieval here.
Meters only an area at the very center of the frame, as indicated by the spot metering circle on the viewfinder focusing screen.
|After changing exposure mode the camera provides a 'guide display' on the LCD monitor which helps to describe the function of that mode. It also provides a quick reference of the current camera settings such as metering, auto focus mode, white balance etc.|
Top of camera controls (right)
On the top right of the camera we have the front dial, main power switch which also serves a preview function which surrounds the shutter release button. To the left of this the 'green button' which is used to reset Program mode and has functions in other exposure modes. On the top rear of the camera 'under your thumb' are the rear dial, the AE-Lock, exposure compensation and AF buttons. The function of the front and rear dials can be set on a per-mode basis via the custom menu.
Shooting mode controls
Auto exposure lock (AE-Lock)
Hold this button and turn the front dial to set exposure compensation. By default the range is -3.0 to +3.0 EV in 1/2 EV steps, if you switch to 1/3 EV steps the range reduces to -2.0 to +2.0 EV.
Play mode controls
|Protect / Unprotect
Press to protect or unprotect the current image, press again to perform this action on all images. This sets the filesystem 'read only' flag which protects the image from accidental deletion using the 'delete' option but does not protect it from formats.
