A 12-megapixel camera from Pentax with a 2.9-inch LCD, 3x optical zoom, an image stabilizer and manual controls.


The Q-S1 + Standard ZOOM 5-15 mm 1:2.8-4.5 ED AL (IF) is a 12-megapixel camera with a kit lens that has a 35mm-equivalent focal length range of 27.5mm-83mm. It has a 2.9-inch LCD (460,000 pixels). Because it accepts interchangeable lenses but does not have a mirror and through-the-lens viewfinder, we consider this model a mirrorless SLR-like camera. The camera's kit lens has a maximum aperture of f/2.8. The camera's shutter speed range is 30 seconds to 1/2000 of a second. The Q-S1 + Standard ZOOM 5-15 mm 1:2.8-4.5 ED AL (IF) stores photos and video on SD/SDHC/SDXC memory cards but has no on-board storage. It captures images as JPEG or RAW files at a top resolution of 4000 x 3000 and full HD-resolution video as MOV files at a top resolution of 1920 x 1080. This mirrorless has 49 autofocus points, 26 exposure modes, and an exposure compensation control that can be set at +/-3 EV. It has exposure bracketing, which allows you to take multiple exposures of a single scene. It has a high-dynamic-range mode, which helps capture as much tonal range possible. The image stabilization system for this camera is mechanical. The Q-S1 + Standard ZOOM 5-15 mm 1:2.8-4.5 ED AL (IF) measures 4.3 inches wide by 2.3 inches high by 1.4 inches deep, and weighs 8 ounces (with battery, memory card, and strap).

Exposure modes Exposure modes These modes or settings refer to those available directly on the main mode dial and often include the main exposure modes, such as program auto, shutter priority, aperture priority and manual. Select scene modes, such as portrait, sports, close-up and landscape modes as well as additional settings can be found on this dial as well.
Live view Live view This feature lets you compose directly on the camera's LCD, as you would on a point-and-shoot camera.
Color space Color space This refers to computerized models of color ranges that a camera can reproduce. The two most common are sRGB and Adobe RGB. In terms of size, Adobe RGB has a larger color range than sRGB. Another model, ProPhoto RGB, has one of the largest ranges. Color spaces can generally be set via your SLR's menus.

PC flash sync jack PC flash sync jack Although the hot shoe is the most common method, you can also use this terminal to connect your flash to your SLR body.


LCD size (in.) LCD size Diagonal measurement of the LCD monitor screen.
Max. ISO Max. ISO This is the SLR's highest sensor sensitivity at full resolution.
35mm equivalent multiplier 35mm equivalent multiplier Many SLRs have sensors that are smaller than the actual size of one frame of 35mm film, which changes a lens's effective focal length. To determine the equivalent focal length, you multiply the lens's focal length by the appropriate multiplication factor. Most Nikon SLRs have a 1.5x factor, which changes the effective focal length of a 50mm lens to 75mm. An Olympus SLR's 2x factor would change a 50mm lens to 100mm.
Max. buffer size JPEG/RAW Max. buffer size JPEG/RAW This number essentially calculates the number of images (either JPEG or RAW files) that can be stored in a buffer (where files are stored temporarily) before the camera slows down.
Shutter speed range Shutter speed range Shutter speed controls the length of time that the camera lets in light to expose the camera's sensor. This specification shows the range of selectable shutter speeds by defining the minimum and maximum shutter speeds.
30 - 1/2000
Height (in.) Height The height of the camera body is measured in inches and rounded to the nearest tenth of an inch.
Still image formats Still image formats The type of image file (or image file combinations) the camera uses to record and store digital images. Examples include JPEG and RAW file formats.
Width (in.) Width The width of the camera body is measured in inches and rounded to the nearest tenth of an inch.
LCD pixel count LCD pixel count Total number of pixels of the LCD monitor. In general, the higher the number of pixels, the clearer and sharper the image will be.
Depth (in.) Depth The depth of the camera body is measured in inches and rounded to the nearest tenth of an inch.
Memory card slots/type Memory card slots/type The number of slots and the type of memory card format the SLR uses for storing images.
Full frame Full frame A full-frame image sensor is the size of one frame of 35mm film and significantly larger than sensors found in many other digital cameras. Often, this type of sensor handles a wider variety of lighting situations more accurately. It also limits the amount of visual noise that can distort and degrade an image.
