Pentax K100D SLR Review
Camera Controls, Storage, I/O, & Power
The controls on the grip side of the camera: the Power switch / DOF Preview and Shutter
Release button, the +/- exposure compensation button which is used in Manual mode to
change the aperture value. The data LCD is not illuminated but current settings can be
seen on the color LCD using the Info button (see next page).
The data LCD display indicates: Shutter speed, Aperture value, Flash Information (Auto, Flash-On, Flash-Off, Red-eye reduction), Single frame/Continuous advance/Self-timer/Remote control, Metering Information, Focus point indicator, Auto bracketing, Preset/Manual white balance information, Battery information, Exposure compensation factor and Number of recordable images/Exposure compensation value.
The Mode Dial has positions for: Flash Off, Night Scene Portrait, Action, Macro, Landscape,
Portrait, Auto Picture, Scene, Program AE, Shutter-Priority AE, Aperture-Priority AE,
Manual and Bulb. Scene mode has menu-selectable settings for Night Scene, Surf & Snow, Text,
Sunset, Kids, Pet, Candlelight and Museum.
On the back is the e-dial which is used to change shutter speed, aperture and other
settings. In playback it functions as the Index-Zoom dial (see next page for digital
controls). The AE-L is used to lock the Auto Exposure to allow you to reframe without
changing the exposure value.
Below the Mode Dial is the Flash Release button to open the pop-up flash when in any
mode other than No Flash or Auto Picture, or several of the scene modes.
Images are stored on Secure Digital (SD) flash memory cards. The K100D can use any
capacity SD card up to 2GB, and SDHC cards exceeding 2GB; shown here is the spacious and speedy
Sandisk Ultra II 2GB SD card.
The Pentax K100D can powered by either four AA type (lithium, alkaline, nickel-metal hydride) or two CR-V3 lithium batteries. Lithium type provide the best performance for one-use batteries and offer the longest "shelf life" and low temperature usability. Rechargeable NiMH AA's are more economical and ecologically sound than one-use batteries that end up in the landfill.
Pentax recommends against the use of oxyride and rechargeable CR-V3 lithium
batteries because some batteries deliver too high of a voltage (i.e. 3.7v versus
the 3v delivered by one-use CR-V3 cells.)
