The Pentax Q-S1 is a compact digital mirrorless interchangeable lens camera announced by Ricoh under the Pentax brand on August 4, 2014. It replaces the Pentax Q7, and is part of Pentax' Q system, the most compact digital interchangeable lens camera system as of September 2014, with crop factors ranging from 4.6 (Q7, Q-S1) to 5.6 (Q, Q10). The Q-S1 has in-body image stabilization as well as a built in flash. It is available in a variety of color combinations. In video mode it can auto focus while shooting with the 01, 02 and 08 lenses. Discontinued as of January, 2020.

Ricoh
is a Japanese multinational imaging and electronics company. It was founded by the now-defunct commercial division of the Institute of Physical and Chemical Research (Riken) known as the ''Riken Concern'', on 6 February 1936 as . Ricoh's headquarters are located in Ōta, Tokyo. Ricoh produces electronic products, primarily cameras and office equipment such as printers, photocopiers, fax machines, offers Software as a Service (SaaS) document management applications such as DocumentMall, RicohDocs, GlobalScan, Print&Share, MakeLeaps and also offers Projectors. In the late 1990s through early 2000s, the company grew to become the largest copier manufacturer in the world. During this time, Ricoh acquired Savin, Gestetner, Lanier, Rex-Rotary, Monroe, Nashuatec, IKON and most recently IBM Printing Systems Division / Infoprint Solutions Company. Although the Monroe brand was discontinued, products continue to be marketed worldwide under the remaining brand names. In 2006, Ri ...

Mirrorless Interchangeable Lens Camera
A mirrorless camera (sometimes referred to as a mirrorless interchangeable-lens camera (MILC) or digital single-lens mirrorless (DSLM)) is a digital camera which, in contrast to DSLRs, does not use a mirror in order to ensure that the image presented to the photographer through the viewfinder is identical to that taken by the camera. They have come to replace DSLRs, which have historically dominated interchangeable lens cameras. Other terms include electronic viewfinder interchangeable lens (EVIL) and compact system camera (CSC). When compared to similar DSLRs, these cameras can be smaller, lighter, and quieter. In cameras with mirrors, light from the lens is directed to either the image sensor or the viewfinder. This is done using a mechanical movable mirror which sits behind the lens. By contrast, in a mirrorless camera, the lens always shines light onto the image sensor, and what the camera sees is displayed on a screen for the photographer. Some mirrorless cameras also ...

Pentax
was a Japanese camera and optical equipment manufacturer. Currently, it exists as the Pentax Life Care Business Division of Hoya's medical endoscope business, as well as the digital camera brand of Ricoh Imaging, a subsidiary of Ricoh. Pentax, founded in 1919 as a town workshop specializing in polishing eyeglass lenses, developed Japan's first single-lens reflex camera, the Asahiflex, in 1952. By 2006, Pentax's domestic market share in digital cameras had declined to 4%. In 2007, Pentax was acquired by Hoya and subsequently merged with the company the following year. In 2011, Hoya spun off the Pentax brand's digital camera business, which was then acquired by Ricoh, leading to the establishment of Pentax Ricoh Imaging (current Ricoh Imaging). As a response to growing interest in film photography, Pentax launched the Pentax 17 on June 17, 2024. The Pentax 17 is a half-frame film camera. This launch marks the first Pentax film camera in over two decades. Corporate history ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pentax Q Series
The Pentax Q series is a series of mirrorless interchangeable-lens cameras made by Pentax and introduced in 2011 with the initial model Pentax Q. , it was the world's smallest, lightest interchangeable lens digital camera. The first models used a 1/2.3" (6.17 x 4.55 mm) back-illuminated sensor CMOS image sensor. The Q7, introduced in June 2013, uses a larger 1/1.7" type sensor (7.44 x 5.58 mm). The Q system is now discontinued. Characteristics The Pentax Q and Q10 sensors have a crop factor of 5.53× while the Pentax Q7 and Q-s1 have a crop factor of 4.65×. The original Pentax Q sensor has a 12.4 megapixels with 1.52 μm pixel pitch. All Pentax Q system cameras have a short flange focal distance (FFD) of 9.2mm. With a 5.53× crop factor, an adapted 100mm lens has the equivalent field of view (FOV) of a 553mm telephoto in the 35mm full-frame format. An additional implication of these relatively large crop factors is that depth of field (DOF) is proportionally increas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crop Factor
In digital photography, the crop factor, format factor, or focal length multiplier of an image sensor format is the ratio of the dimensions of a camera's imaging area compared to a reference format; most often, this term is applied to digital cameras, relative to 35 mm film format as a reference. In the case of digital cameras, the imaging device would be a digital image sensor. The most commonly used definition of crop factor is the ratio of a 35 mm frame's diagonal (43.3 mm) to the diagonal of the image sensor in question; that is, \text = \text_ / \text_. Given the same 3:2 aspect ratio as 35mm's 36 mm × 24 mm area, this is equivalent to the ratio of heights or ratio of widths; the ratio of sensor areas is the square of the crop factor. The crop factor is sometimes used to compare the field of view and image quality of different cameras with the same lens. The crop factor is sometimes referred to as the focal length multiplier ("Film") since multiplying a lens f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Image Stabilization
Image stabilization (IS) is a family of techniques that reduce motion blur, blurring associated with the motion of a camera or other imaging device during exposure (photography), exposure. Generally, it compensates for panning (camera), pan and tilt (camera), tilt (angular movement, equivalent to aircraft principal axes, yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation about the optical axis (aircraft principal axes, roll). It is mainly used in high-end image-stabilized binoculars, digital camera, still and video camera, video cameras, astronomical telescopes, and also smartphones. With still cameras, camera shake is a particular problem at slow shutter speeds or with long focal length lenses (telephoto lens, telephoto or zoom lens, zoom). With video cameras, camera shake causes visible frame-to-frame jitter (optics), jitter in the recorded video. In astronomy, the problem of lens shake is added to Astronomical seeing, ...

List Of Smallest Mirrorless Cameras
This is a list of the lightest and smallest mirrorless digital cameras ever released with an interchangeable lens mount, excluding smartphones and action cameras, sorted by weight including battery and memory card. Nearly all the lightest models have been discontinued, as smartphone cameras have rapidly improved and taken over their market. Some high-end smartphones now exceed several of these models in weight, sensor size, and functionality. (For example, an iPhone 15 Pro Max weighs 221 g, and a Galaxy S24 Ultra weighs 233 g.) The lightest mirrorless cameras in production today are the Olympus E-P7 at 337 g and Sony ZV-E10 at 343 g. The lightest models in production with an electronic viewfinder (EVF) are the Panasonic G100D at 346 g and Canon R100 at 356 g. With the exception of the E-P7's in-body image stabilization (IBIS), these models eschew certain hardware features, such as IBIS and weather sealing, that add weigh ...
