Body Elements

The K-01's built-in flash has a guide number of 12 (m at ISO 100). It's double-hinged design raises it 43mm above the top of the lens mount, flush with the edge of the camera body.
A hotshoe sits directly behind the pop-up flash. When mated with a Pentax flash unit the camera can sync at 1/180 sec.

To the left of the hotshoe is a button marked 'UP', which opens the built-in flash. The button only functions with the camera powered on.
Behind the small holes on either side of the lens mount are the camera's stereo microphones.
A dedicated AF/MF focus mode switch sits along the left side of the camera. The switch has a noticeably stiff resistance, preventing accidental operation when mounting and unmounting lenses.
Two small holes located higher up along the same side of the camera as the focus mode switch conceal the K-01's speaker, used for video playback.
Located towards the bottom of the hand grip is an IR (infrared) remote control receiver. When using an optional Pentax remote, the camera can be triggered from a maximum distance of 4m.

This unit also houses a self-timer lamp.
Sitting beneath the right edge of the mode dial is the autofocus assist light. You can disable its use in the Rec. mode menu.
The signature logo of designer Marc Newson is displayed on the bottom of the camera. The battery door is located well to the side of the tripod socket which means you can change the battery with the camera mounted on a tripod.
The K-01 is powered by the same large D-LI90 Li-ion battery found in the Pentax K-5 and 645D. When placed in a K-01, it has a CIPA rating of approximately 500 shots.
USB and HDMI ports are found on the right side of the camera. Disappointingly, they are concealed behind a large rubber flap which we find a bit fiddly to close securely.

The SD card slot is located here as well, behind a second door, this one made of plastic. The camera accepts UHS Class 1 SD cards.

Having to open and close two doors makes swapping SD cards a touch more involved than we'd like.

A 3.5mm external stereo microphone input is located behind yet another rubber flap.
