PENTAX D-BG8 Battery Grip (Black) camera accessory

SKU CH-XZVB-DC8PM

Dust- and weather-resistant battery grip adds vertical controls and extends shooting time with a D-Li90P cell

  • TypeAccessory
  • Extended shooting time with a second D-Li90P battery
  • Comfortable vertical shooting via duplicate shutter and dials
  • Dust and weather resistant construction protects the camera
  • Additional controls include Smart Function and focus lever
  • Convenient in-camera USB charging of the grip battery

Built for Pentax K-3 Mark III

The Pentax D-BG8 battery grip attaches to the K-3 Mark III SLR and duplicates key controls for vertical shooting. It accepts the same D-Li90P lithium-ion battery used by the camera body, so spares are interchangeable. Outdoor photographers gain dust and weather resistance that matches the camera's sealing.

Sustained shooting with duplicated controls

During long sessions the grip lets you operate shutter release, Smart Function, AF/AE lock, exposure compensation and green button without changing hand position. Electronic dials and a focus-point selector lever work identically to the body controls, so muscle memory transfers directly. Power comes from the installed D-Li90P cell, effectively doubling the available capacity.

Weather-sealed ergonomics and USB charging

The grip's dust and weather-resistant construction maintains the camera's environmental protection when mounted. Added bulk improves balance with larger lenses and reduces hand fatigue during extended use. The battery inside the grip charges through the camera's USB connection, so no separate charger is required.

Questions about this item

Does the D-BG8 grip add any fan noise or heat when the K-3 Mark III runs all day?

The D-BG8 is a passive battery holder with no fan or active electronics, so it adds no audible noise or measurable heat during extended use.

What battery must I already own for the D-BG8 to power my K-3 Mark III?

You need at least one Pentax D-Li90P lithium-ion battery; the grip accepts the same cell that powers the camera body.

Will the D-BG8's duplicate shutter release and dials work the same as the K-3 Mark III's built-in controls?

Yes — the grip mirrors the body's shutter button, front and rear e-dials, AF/AE lock, exposure compensation, green button and focus-point lever for identical vertical operation.
