Battery compartment

The battery compartment on the K10D is in the base of the hand grip behind a locking latch which fits flush when close but must be flipped up to open. The compartment door is spring loaded to open and features a small rubber o-ring ensuring a weather-proof seal when closed.

The battery used is the new D-LI50 Lithium-Ion rechargeable which is rated as having a capacity of 1620 mAh at 7.4V (12 Wh). The 'hole' you can see in the base of the camera beside the battery compartment is the battery grip terminal (this would normally be protected by a rubber cover).

Battery grip (optional)

The D-BG2 optional battery grip attaches via three fixed pins which help support and locate the grip onto the base of the camera, it is held in place by a thumb screw into the tripod mount. Electrical connection is made via a single group of contacts near the center of the grip which fit into the dedicated grip terminal in the base of the camera. Just like the camera the grip is also dust and weather proof and makes use of rubber seals in joints and around controls.

The grip provides improved landscape (horizontal) grip as well as a portrait (vertical) grip and repeated controls; power on/off/preview, shutter release, green button, both control dials, exposure compensation and AE lock. Because of its design one battery remains in the camera.

The D-BG2 provides capacity for one additional D-LI50 Lithium-Ion battery as well as storage for an SD card and the camera IR remote. Just like the battery and SD compartment doors the battery grip door opens using a twisting lever lock which must be raised before it can be turned.

Secure Digital (SD/SDHC) compartment

The K10D supports SD and SDHC media, the compartment door is in the side of the hand grip and is opened using the same type of twisting lever lock as the battery compartment. Turn the lock and the compartment door springs open, the retention of the card is on a simple press to insert, press to remove. There is a rubber seal on the body where the door meets it when closed (ensuring weatherproofing). SD cards provide capacities of up to 2 GB, SDHC for capacities of 4 GB or more.


On the left side of the camera behind another weather-proofed door are all of the camera's connectors. These are (from top to bottom); wired remote, combination USB 2.0 and video out and DC-IN (8.3 V).

Camera base / tripod mount

The base of the camera has a metal tripod mount aligned with the lens axis and focal plane, just to the left of this is the battery grip terminal, which would normally be protected by a rubber cover.

Pop-up flash

The K10D has a 'P-TTL' pop-up flash unit which has a manual catch-type release. The unit itself has a guide number of 11 (which equates to an approximate maximum range of 3.9 m at F2.8, ISO 100) and a field of view coverage of approximately 18 mm. Flash sync speed is 1/180 sec. The K10D doesn't have a dedicated AF assist lamp, instead it strobes the flash unit (if raised) to provide additional illumination to the AF system.


The K10D hot-shoe can be used with Pentax specific flash units to achieve P-TTL auto flash, high-speed sync and wireless (such as the AF540FGZ or AF360FGZ) or simply to provide a sync signal to third party flash or studio strobes.

Lens Mount

The K10D has a KAF2 bayonet lens mount which can take lenses with a KAF2, KAF or KA mount lenses, it also provides an option to use the lens aperture ring. Obviously Pentax now has a range of DA 'designed for digital' lenses which are designed for the APS size sensor (smaller imaging circle) which are smaller and lighter than full frame lenses. The K10D's sensor is approximately APS-C size which equates to a 1.5x field-of-view crop compared to a 35 mm film camera, so a 50 mm lens on the K10D will produce a field-of-view of approximately 75 mm equivalent.

Shutter Release Sound

In some of our digital SLR reviews we now provide a sound recording of a continuous burst of shots to provide a sample of the shutter release sound. The CF card used was a SanDisk 2 GB Extreme IV.
