Manufacturer description

PENTAX Corporation is pleased to introduce the PENTAX K110D, an entry-class lens-interchangeable digital SLR camera that combines a host of advanced technologies with a simple, user-friendly operation system and a compact, lightweight body. It brings high-quality digital SLR photography to everyone — especially to first-time digital SLR users.

Developed as a starter camera for beginning digital SLR photographers, the K110D is designed to capture high-quality images with simplified operation in a variety of applications, including the documentation of hobby scenes and the preservation of family events. In addition to a sophisticated autofocus system that rivals the performance of higher-grade models, the high-performance K110D offers such outstanding features as a bright, clear viewfinder, an extra-large, wide-view LCD monitor, and 6.1 effective megapixels.

Major Features

11-point wide-frame AF to capture off-center subjects in crisp focus

The K110D’s sophisticated SAFOX VIII autofocus system features 11 sensor points (with nine cross-type sensors in the middle) to automatically focus on the subject with utmost precision, even when it is positioned off center. The in-focus sensor point is automatically superimposed in red in the viewfinder for at-a-glance confirmation. This high-precision AF system offers a choice of two AF modes: the conventional single AF, and the continuous AF,** which maintains focus on the moving subject as long as the shutter release button is pressed halfway down.

** The continuous AF mode is selectable by the user only when P, Tv, Av, M or B is selected as a shooting mode on the mode dial. This mode is automatically activated by the camera when the Auto Picture Program, or one of the Picture or Scene modes, is selected.

Bright, clear viewfinder

The K110D features a lightweight penta-mirror viewfinder, which combines a PENTAX-original finder optics with a Natural-Bright-Matte II focusing screen to deliver a bright, clear subject image with a 0.85-times magnification and a 96-percent field of view.

Large LCD monitor to facilitate image viewing and menu setting

The K110D incorporates a large 2.5-inch color LCD monitor on its back panel. Its wide-view design allows the photographer to check the monitor image over 140 degrees vertically and horizontally, ensuring effortless image viewing even from a diagonal position. With a total of approximately 210,000 pixels, it also offers digital zooming of playback images up to 12 times for easy confirmation of the image’s focusing status and details. The large monitor size allows for large letters, digits and icons on the menu screens to facilitate menu confirmation and camera operations. In addition, the color scheme between the menu listings and the background is optimized for each menu screen to assure at-a-glance confirmation, even under varying shooting conditions.

Auto Picture Mode for effortless point-and-shoot SLR photography

The K110D offers the PENTAX-developed Auto Picture Mode, which automatically and instantly selects one of the five Picture modes — including Portrait, Landscape and Macro — by calculating various photographic factors to assure optimum results. Since this advanced shooting mode takes away all the concerns about aperture, shutter-speed, white-balance, saturation, contrast and sharpness settings, the photographer can concentrate on image composition and shutter opportunity.

Auto sensitivity control up to 3200 standard output sensitivity

The K110D features an auto sensitivity control function, which automatically sets the optimum standard output sensitivity — up to 3200, which is the highest automatic setting in its class — based on such data as the subject’s brightness level and the lens’ focal length. Since this function allows the use of higher shutter speeds in poor lighting situations (such as indoor sports events and night scenes), it helps the photographer to effectively reduce camera shake and prevent blurred images.

AA-battery power supply for easy battery replacement on the road

The K110D is powered by four AA-size batteries — available nearly everywhere around the globe — for worry-free batter replacement. It also accepts two CR-V3 lithium batteries.

True-to-life, rich-gradation images assured by 6.1 effective megapixels

The K110D features a large, high-performance 23.5mm x 15.7mm CCD as its image sensor, assuring the faithful reproduction of the desired photographic intention in the resulting images — from images with beautiful out-of-focus backgrounds to those with edge-to-edge sharpness. By combining 6.1 effective megapixels with a high-performance imaging engine and advanced image-processing technologies, the K110D is designed to produce beautiful, true-to-life images that are rich in gradation. What’s more, it offers a choice of two finishing touches of “Natural” or “Bright” to create a distinctive atmosphere.

Compatibility with existing PENTAX interchangeable lenses

The K110D is compatible with all existing PENTAX interchangeable lenses — both old and new.** This compatibility lets the photographer use various lenses for the same subject, or select the most appropriate lens for a given situation, assuring the top visual creativity available only through SLR photography.

** Lenses compatible with the K110D are: K-, KA-, KAF- and KAF2-mount lenses; screw-mount lenses (with an adapter); 645-system lenses (with an adapter); and 67-system lenses (with an adapter). Certain lenses may lose part of their functions.

Super-compact, ultra-lightweight body, with outstanding rigidity

While the K110D is designed to be compact and lightweight to enhance operability and portability, it also incorporates a newly developed stainless-steel chassis and a fiber-reinforced engineering plastic housing to reinforce its overall rigidity and durability.

Cannot perform comparison

Cannot compare the lens to itself.

Image stabilizer

A technology used for reducing or even eliminating the effects of camera shake. Gyro sensors inside the lens detect camera shake and pass the data to a microcomputer. Then an image stabilization group of elements controlled by the microcomputer moves inside the lens and compensates camera shake in order to keep the image static on the imaging sensor or film.

The technology allows to increase the shutter speed by several stops and shoot handheld in such lighting conditions and at such focal lengths where without image stabilizer you have to use tripod, decrease the shutter speed and/or increase the ISO setting which can lead to blurry and noisy images.

Original name

Lens name as indicated on the lens barrel (usually on the front ring). With lenses from film era, may vary slightly from batch to batch.

Format

Format refers to the shape and size of film or image sensor.

35mm is the common name of the 36x24mm film format or image sensor format. It has an aspect ratio of 3:2, and a diagonal measurement of approximately 43mm. The name originates with the total width of the 135 film which was the primary medium of the format prior to the invention of the full frame digital SLR. Historically the 35mm format was sometimes called small format to distinguish it from the medium and large formats.

APS-C is an image sensor format approximately equivalent in size to the film negatives of 25.1x16.7mm with an aspect ratio of 3:2.

Medium format is a film format or image sensor format larger than 36x24mm (35mm) but smaller than 4x5in (large format).

Angle of view

Angle of view describes the angular extent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view.

As the focal length changes, the angle of view also changes. The shorter the focal length (eg 18mm), the wider the angle of view. Conversely, the longer the focal length (eg 55mm), the smaller the angle of view.

A camera's angle of view depends not only on the lens, but also on the sensor. Imaging sensors are sometimes smaller than 35mm film frame, and this causes the lens to have a narrower angle of view than with 35mm film, by a certain factor for each sensor (called the crop factor).

This website does not use the angles of view provided by lens manufacturers, but calculates them automatically by the following formula: 114.6 * arctan (21.622 / CF * FL),

where:

CF – crop-factor of a sensor,
FL – focal length of a lens.

Mount

A lens mount is an interface — mechanical and often also electrical — between a camera body and a lens.

A lens mount may be a screw-threaded type, a bayonet-type, or a breech-lock type. Modern camera lens mounts are of the bayonet type, because the bayonet mechanism precisely aligns mechanical and electrical features between lens and body, unlike screw-threaded mounts.

Lens mounts of competing manufacturers (Canon, Nikon, Pentax, Sony etc.) are always incompatible. In addition to the mechanical and electrical interface variations, the flange focal distance can also be different.

The flange focal distance (FFD) is the distance from the mechanical rear end surface of the lens mount to the focal plane.

Lens construction

Lens construction – a specific arrangement of elements and groups that make up the optical design, including type and size of elements, type of used materials etc.

Element - an individual piece of glass which makes up one component of a photographic lens. Photographic lenses are nearly always built up of multiple such elements.

Group – a cemented together pieces of glass which form a single unit or an individual piece of glass. The advantage is that there is no glass-air surfaces between cemented together pieces of glass, which reduces reflections.

Focal length

The focal length is the factor that determines the size of the image reproduced on the focal plane, picture angle which covers the area of the subject to be photographed, depth of field, etc.

Speed

The largest opening or stop at which a lens can be used is referred to as the speed of the lens. The larger the maximum aperture is, the faster the lens is considered to be. Lenses that offer a large maximum aperture are commonly referred to as fast lenses, and lenses with smaller maximum aperture are regarded as slow.

In low-light situations, having a wider maximum aperture means that you can shoot at a faster shutter speed or work at a lower ISO, or both.

Closest focusing distance

The minimum distance from the focal plane (film or sensor) to the subject where the lens is still able to focus.

Closest working distance

The distance from the front edge of the lens to the subject at the maximum magnification.

Magnification ratio

Determines how large the subject will appear in the final image. For example, a magnification ratio of 1:1 means that the image of the subject formed on the film or sensor will be the same size as the subject in real life. For this reason, a 1:1 ratio is often called "life-size".

Manual focus override in autofocus mode

Allows to perform final focusing manually after the camera has locked the focus automatically. Note that you don't have to switch camera and/or lens to manual focus mode.

Manual focus override in autofocus mode

Allows to perform final focusing manually after the camera has locked the focus automatically. Note that you don't have to switch camera and/or lens to manual focus mode.

Electronic manual focus override is performed in the following way: half-press the shutter button, wait until the camera has finished the autofocusing and then focus manually without releasing the shutter button using the focusing ring.

Manual diaphragm

The diaphragm must be stopped down manually by rotating the detent aperture ring.

Preset diaphragm

The lens has two rings, one is for pre-setting, while the other is for normal diaphragm adjustment. The first ring must be set at the desired aperture, the second ring then should be fully opened for focusing, and turned back for stop down to the pre-set value.

Semi-automatic diaphragm

The lens features spring mechanism in the diaphragm, triggered by the shutter release, which stops down the diaphragm to the pre-set value. The spring needs to be reset manually after each exposure to re-open diaphragm to its maximum value.

Automatic diaphragm

The camera automatically closes the diaphragm down during the shutter operation. On completion of the exposure, the diaphragm re-opens to its maximum value.

Fixed diaphragm

The aperture setting is fixed at F/ on this lens, and cannot be adjusted.

Number of blades

As a general rule, the more blades that are used to create the aperture opening in the lens, the rounder the out-of-focus highlights will be.

Some lenses are designed with curved diaphragm blades, so the roundness of the aperture comes not from the number of blades, but from their shape. However, the fewer blades the diaphragm has, the more difficult it is to form a circle, regardless of rounded edges.

At maximum aperture, the opening will be circular regardless of the number of blades.

Weight

Excluding case or pouch, caps and other detachable accessories (lens hood, close-up adapter, tripod adapter etc.).

Maximum diameter x Length

Excluding case or pouch, caps and other detachable accessories (lens hood, close-up adapter, tripod adapter etc.).

For lenses with collapsible design, the length is indicated for the working (retracted) state.

Weather sealing

A rubber material which is inserted in between each externally exposed part (manual focus and zoom rings, buttons, switch panels etc.) to ensure it is properly sealed against dust and moisture.

Lenses that accept front mounted filters typically do not have gaskets behind the filter mount. It is recommended to use a filter for complete weather resistance when desired.

Fluorine coating

Helps keep lenses clean by reducing the possibility of dust and dirt adhering to the lens and by facilitating cleaning should the need arise. Applied to the outer surface of the front and/or rear lens elements over multi-coatings.

Filters

Lens filters are accessories that can protect lenses from dirt and damage, enhance colors, minimize glare and reflections, and add creative effects to images.

Lens hood

A lens hood or lens shade is a device used on the end of a lens to block the sun or other light source in order to prevent glare and lens flare. Flare occurs when stray light strikes the front element of a lens and then bounces around within the lens. This stray light often comes from very bright light sources, such as the sun, bright studio lights, or a bright white background.

The geometry of the lens hood can vary from a plain cylindrical or conical section to a more complex shape, sometimes called a petal, tulip, or flower hood. This allows the lens hood to block stray light with the higher portions of the lens hood, while allowing more light into the corners of the image through the lowered portions of the hood.

Lens hoods are more prominent in long focus lenses because they have a smaller viewing angle than that of wide-angle lenses. For wide angle lenses, the length of the hood cannot be as long as those for telephoto lenses, as a longer hood would enter the wider field of view of the lens.

Lens hoods are often designed to fit onto the matching lens facing either forward, for normal use, or backwards, so that the hood may be stored with the lens without occupying much additional space. In addition, lens hoods can offer some degree of physical protection for the lens due to the hood extending farther than the lens itself.

Teleconverters

Teleconverters increase the effective focal length of lenses. They also usually maintain the closest focusing distance of lenses, thus increasing the magnification significantly. A lens combined with a teleconverter is normally smaller, lighter and cheaper than a "direct" telephoto lens of the same focal length and speed.

Teleconverters are a convenient way of enhancing telephoto capability, but it comes at a cost − reduced maximum aperture. Also, since teleconverters magnify every detail in the image, they logically also magnify residual aberrations of the lens.

Lens caps

Scratched lens surfaces can spoil the definition and contrast of even the finest lenses. Lens covers are the best and most inexpensive protection available against dust, moisture and abrasion. Safeguard lens elements - both front and rear - whenever the lens is not in use.
