Camera Overview — Pentax Q-S1

The Pentax Q-S1 is an ultra-compact mirrorless camera built around a 1/1.7-inch sensor delivering 12.4 megapixels of resolution. It uses the Pentax Q lens mount, offering interchangeable lens flexibility in a body measuring just 105 x 58 x 34 mm and weighing a mere 203g — making it one of the more pocketable interchangeable-lens cameras available. The body is constructed from aluminum alloy with a leatherette wrap, giving it a premium, retro feel despite its compact footprint.

Powering the imaging pipeline is the Q Engine processor, which handles a native ISO range of 100 to 12800. In-body sensor-shift image stabilization is included, a notable feature at this size class. Burst shooting reaches up to 5 frames per second, and the autofocus system uses contrast detection with 25 selectable focus points.

Video capability tops out at 1080p at up to 30fps in 8-bit color. The 3.0-inch fixed TFT-LCD display has a resolution of 460,000 dots, and there is no viewfinder. Connectivity includes Micro HDMI output and USB, while Wi-Fi and Bluetooth are absent.

A built-in pop-up flash with a guide number of 4.9 at ISO 100 is included, along with a standard hot shoe for external flash. Storage is handled via SD, SDHC, or SDXC cards, and battery life is rated at approximately 250 shots per charge using the D-LI68 lithium-ion battery.

Description — Pentax Q-S1

The Pentax Q-S1 is a compact mirrorless camera built on the Pentax Q lens mount system, pairing a 12.4 MP resolution 1/1.7-inch sensor with the Q Engine image processor in a body that measures just 105 x 58 x 34 mm and weighs 203g. The aluminum alloy with leatherette wrap construction gives the camera a solid, refined feel that belies its small size. Shooting flexibility comes from a native ISO range of 100 to 12800, in-body sensor-shift image stabilization, and a burst rate of up to 5 fps.

Autofocus relies on contrast detection with 25 selectable points. For composition, the 3.0-inch fixed TFT-LCD with 460,000 dots resolution is the sole framing tool — no viewfinder is present. Video reaches 1080p at up to 30fps in 8-bit color.

Eleven creative color profiles — including Bleach Bypass, Reversal Film, and Cross Processing — apply to both stills and video. A built-in pop-up flash rated GN 4.9 at ISO 100 and a standard hot shoe round out the imaging tools, while Micro HDMI (Type D) and USB handle external connectivity.
