Pentax is careful about design, adding touches of color to their cameras and maintaining visual themes throughout camera lines. The *ist DSLRs, which the K series cameras replace, have a science-fiction look to them, with sweeping contours that, in places, seem pure style – they don't accommodate camera parts or improve handling.

 

The Pentax K100D and its stable mates have pulled back from that, with a more conventional, utilitarian design. The stylistic flourishes, such as the diagonal ridge on the grip, also improve the camera's function.

 

The K100D, the K10D and the K110D look very similar, and they clearly share many components. This design consistency benefits the K100D, because it shares the higher-end K10D's sturdy body parts and excellent fit and finish.

 

Size / Portability (8.25)

At 5.1 x 3.6 x 2.8 inches, the Pentax K100D is on the small end of DSLRs, though many price-competitive compact cameras are smaller. The size difference between the cameras does not affect portability – the slightly more petite Nikon D40x isn't easier to pack or carry. The difference may influence how comfortable the cameras are to use, however. The Nikon's grip cramps the lens mount, which may make the fatter Nikon lenses uncomfortable to use. The K100D shouldn't present that problem because it has more space between the grip and the lens mount, and Pentax lenses are generally compact.

Handling Ability (7.75)

The Pentax K100D is comfortable to hold. The right hand's grip feels very good, with the diagonal ridge on its front a real benefit for comfort and security. The left side's grip surface will be helpful for users who buy Pentax's compact lenses. As noted above, the Pentax K100D is big enough for users with average-size hands to use comfortably.

Control Button / Dial Positioning / Size (7.0)

The Pentax K100D has only one control dial, so setting aperture and shutter speed in manual mode requires pressing a button and turning a dial. It's not as convenient as having two dials. On the other hand, the K100D's buttons, control dial, and mode dial are mechanically solid. They appear durable and are easy to use. The Shake Reduction switch is large – perhaps it's so big because the marketing department wants the feature to be prominently displayed. Still, it's easy to use, and the switch makes it easy to tell if the feature is turned on.

 

Menu (7.0)

The K100D's menus are about as straightforward as the rest of the camera. The text is easy to read and most of the important stuff is higher on each list than more obscure items. There are an appropriate number of menu options for an entry-level DSLR.

Ease of Use (8.0)

The Pentax K100D is laid out clearly and neatly. Both the physical interface – buttons, dials and displays – and the menu structure are logical and straightforward. Flash compensation is buried in the menus, which suggests the K100D isn't meant for serious flash shooters. The Function button adds an extra step to get to ISO, White Balance, Flash sync and Burst Mode. Those are very basic controls, and it would be better if they came up in a single action, rather than in two steps. The method Pentax chose makes the camera back simpler than some competing cameras: the Nikon D80 (actually, it's a step up from the K100D) has a couple of labels for each button because they have separate functions in shooting and playback modes. That might be more confusing than the K100D's setup.

 

Pentax also provides an excellent, thorough, and well-written manual.
