HD PENTAX-DA 15mmF4ED AL Limited

The lenses of the Limited Lens Series offer exceptional premium quality. The HD PENTAX-DA 15mm F4 ED AL Limited, which corresponds to the angle of view of a 23mm lens equivalent to 35mm 35mm format, was developed on the basis of the special design concept of the Limited Lens Series and optimised for digital photography. Important parameters are, on the one hand, the distinctive optics and high-quality feel, and on the other hand, an optical construction that has been subjected to constant evaluation based on test shots and assessments by people. The result, in keeping with the Pentax philosophy, offers the best possible image reproduction and a visual impression that cannot be reproduced by measured values alone..

Features

Outstanding Image Quality

Based on the development philosophy of the Limited Edition series, the PENTAX-DA 15mm F4 ED AL Limited delivers a distinctive visual description in keeping with the series, as well as a high-quality appearance. This is determined by the high quality aluminium used to manufacture the lens barrel, lens hood and cap. It is hand-finished and has a beautiful texture.

The optical design provides a special image look that, due to its low distortion, delivers dramatic images with the finest reproduction of structures. This is achieved by, among other things, an extra-low dispersion ED lens for brilliant sharpness and rich colours, and an AL aspherical lens to reduce aberrations and provide crystal clear images. At the same time, they feature a state-of-the-art HD coating and a round-shaped aperture to offer even higher digital imaging performance when combined with a K-mount camera body.

  

HD Coating to enhance imaging performance

The lens incorporates the PENTAX-developed, multi-layer HD (High Definition) Coating. Compared with conventional multi-layer coatings, it improves light transmittance while reducing average reflectance in the visible ray spectrum. This means that it can deliver clear, well-defined images with minimal flare and ghost images, even under demanding lighting conditions such as backlighting.

 

 

Compact Design

By limiting the maximum aperture to F4, PENTAX designed this lens to be extremely compact and lightweight (189 grams) while providing a 23mm wide angle of view in the 35mm format. This ultra-wide-angle lens is easy to carry, and ideal for casual snapshot photography. Thanks to the reduced curvature of the lens’s front surface, it even lets you attach a filter. Integrated into the front frame, the extendible lens hood also facilitates the operation of attached filters, such as a PL filter.

 

 

SP Coating

SP coating is a PENTAX-original special coating that provides superior performance in repelling water and oils. It is used on the front surface of the first high-performance lens for effective protection of the lens surface. This coating not only prevents adhesion of dust, water drops, oils, and other substances, but it also makes it easy to wipe off objects that adhere to the lens.

Comparison of dirt adhesion (oil-based ink) A lens surface treated with SP Coating has a very smooth surface without the adhesion of the oil-based ink.	Comparison of wipe-off (oil-based ink)  A lens surface treated with SP Coating can be wiped clean more easily and completely, even after the ink has dried.

HD PENTAX-D FA 150-450mmF4.5-5.6ED DC AW

 

There are many situations where it is not possible to get close to the subject. The best example of this is wildlife photography. Whether in the zoo at home, in a wildlife park or on safari, a lens in this focal length range is an indispensable accessory.

With the 35 mm full-frame sensor of a K-1 Mark II, the focal length range of 150-450 mm is available, and the crop factor of APS-C cameras, such as the K-3 Mark III or the K-F, results in a focal length range equivalent to 230-690 mm. The teleconverter HD Pentax-DA AF REAR CONVERTER 1.4AW (limited image range) extends this range by a factor of 1.4.

Features 

Outstanding image description

This lens is treated with the high-grade, multi-layer High Definition Coating . Compared with conventional multi-layer coatings, this PENTAX-original coating assures higher light transmittance and less reflection to deliver bright, high-contrast images free of flare and ghost images, even under demanding lighting conditions such as backlight.

By incorporating three super-low dispersion glass elements and one Anomalous Dispersion Glass element in its optics, it effectively minimizes spherical and chromatic aberrations, while producing crisp, high-quality images with edge-to-edge sharpness,  free of color bleeding.

 

Dustproof, weather-resistant construction

Developed as an AW (All Weather) model, this zoom lens features a dependable dustproof, weather-resistant construction with 21 special seals to prevent the intrusion of water and dust particles into the lens interior.
By pairing it with a PENTAX weather-resistant digital SLR camera body, it assures a durable, reliable digital imaging system that performs superbly in demanding shooting settings — even in rain or mist, or at locations prone to water splashes or spray.

 

 

SP (Super Protect) Coating

SP coating is a PENTAX-original special coating that provides superior performance in repelling water and oils. It is used on the front surface of the first high-performance lens for effective protection of the lens surface. This coating not only prevents adhesion of dust, water drops, oils, and other substances, but it also makes it easy to wipe off objects that adhere to the lens.

Comparison of wipe-off (oil-based ink) 

A lens surface treated with SP Coating can be wiped clean more easily and completely, even after the ink has dried. 

 

Newly installed three-position switch for Quick-Shift Focus System

In order to improve its operability, a three-position switch is newly installed on this lens, allowing instant switching among QFS/A, QFS/M and MF modes. QFS/A is an autofocus-priority mode, which allows the user to switch to manual-focusing operation only when autofocus operation is completed. QFS/M is a manual-focus-priority mode, which enables the user to switch to manual focusing at any time — even when the AF system is in operation. MF mode allows the user to instantly switch to manual focusing with a simple twist of the focus ring on the lens. With a choice of three distinctive modes, the user is assured of speedier, more accurate focusing operation for a given subject or application.

 

Four AF buttons installed on the lens barrel

In order to provide more stable AF operation and better hold of the lens regardless of the camera’s orientation — horizontal or vertical — this lens provides four AF buttons on its barrel — one at every 90 degrees.* The user can assign preferred settings to these AF buttons, including: a Focus Preset mode to preprogram the focus position and instantly shift the focus to that position; and an AF Cancel mode to intentionally fix the focus at a desired point during Continuous AF operation.
* Corresponding models are K-1 Mark II, K-1, KP, K-3II, K-3, K-70, K-S2, K-S1. For K-3 and K-S1, Firmware upgrade is required.

 

Other features 

• Smooth, quiet AF operation using a lens-installed AF driving motor
• Round-shaped diaphragm to produce a natural, beautiful bokeh (defocus) effect, while minimizing the streaking effect of point light sources
• Focus range limiter to minimize AF operation time by fixing the focus range to one of three sub-ranges
• Zoom lock lever to prevent the lens barrel from free-falling
• Detachable tripod mounting with a newly designed anti-falling mechanism

HD PENTAX-D FA^★50mmF1.4 SDM AW

As a standard focal length lens, it impresses with its large aperture and outstanding imaging performance.

The new generation of the ^★star series

Lenses with outstanding performance are marked with a ^★ (star) in the PENTAX system. There are three basic parameters that these lenses fulfil in order to receive this rating:

• Best possible image quality with uniform sharpness from the centre to the edges of the frame.
• Large aperture with particularly expressive image effect.
• High-quality workmanship and materials with high robustness and easy handling

The lenses of the D FA ^★-series not only have to be optimally matched to current shooting sensors, they also have to be designed for future shooting techniques and at the same time remain as compatible as possible with older cameras.

The lenses of the new star series (DA^★ and DFA^★) are distinguished by a new logo, which is no longer glued on but embedded in the lens barrel. 

 

The new standard lens on PENTAX SLR cameras

The technical specifications that a lens in the Stern series has to fulfil are one part of the development process; the other part is the target group and the range of use that the new design of a lens is intended to serve.
Here, the demand from the market for a fast fixed focal length for universal use was taken up. With a focal length of 50 mm and a maximum aperture of F1.4, the new lens is perfect, for example, for reportage shots in available light or for portrait shots with a particularly beautiful image.

 

State-of-the-art optical technology

Glass quality and the treatment and refinement of the individual lenses are still the most important foundations for high image quality. For example, specially selected glass is used in the manufacture of PENTAX lenses, which is treated with a High Definition (HD) coating and an "Aero Bright Coating II" developed by PENTAX. This nanotechnology-based lens coating, which is applied to the multi-layer HD coating with a uniform porous structure, reduces the average reflection in the visible light spectrum to less than 50% of conventional multi-layer coatings, effectively reducing flare and ghosting - even in difficult backlight conditions.

The use of three ultra-low dispersion glass elements and one aspherical element effectively eliminates chromatic and spherical aberrations and produces brilliant images with high contrast and sharp edges.
By minimising distortion even at close focusing distances, the new 50 mm lens delivers razor-sharp, distortion-free images across the entire focal range, from 40 cm to infinity.

The aperture design is also of particular importance. For example, the nine aperture blades in a circular arrangement at apertures F1.4 - F2.8 ensure a particularly balanced and natural bokeh. At the same time, they minimise fringing with point light sources.

The lens is equipped with the KAF4 bayonet, which allows electro-magnetic aperture control on the corresponding Ka-meras (K-1 Mark II, K-1, K-3 II, K-3, KP, K-70, K-S2 and K-S1). This ensures flawless and precise exposure control even when shooting video.  

 

Dustproof and weatherproof construction

A standard, or all-purpose lens, requires particularly comprehensive features. The AW (All Weather) feature, with eight special sealing rings, prevents moisture and dust from penetrating the inside of the lens. In combination with an appropriately weather-resistant digital SLR camera from PENTAX, it forms a durable and reliable camera system, which is also a dependable tool in demanding shooting situations, such as rain, fog, splashing water or sub-zero temperatures down to -10°C.

The front lens is also equipped with Super-Protect (SP) coating. It reduces dirt and moisture adhesion and facilitates cleaning, e.g. of splashing water or greasy substances.



Newly developed ring SDM autofocus drive

The new HD PENTAX-D FAê 50mm F1.4 SDM AW is equipped with a new ring SDM autofocus. It has 7.5 times the torque of conventional lenses. It ensures uniformly fast and quiet focusing via the rear lens group.

Compact, lightweight telephoto zoom lens with outstanding portability

Despite its compact, lightweight design weighing approximately 819 grams, this zoom lens covers the image circle of 35mm full-frame digital SLRs, and provides a focal length range of 70mm to 210mm to facilitate handheld outdoor photography. When mounted on an APS-C-format camera, its focal length range is extended to the equivalent of 107mm to 322mm in the 35mm format. Coupled with its compact, lightweight body, it can be easily integrated in any APS-C-format camera system. In its 20-element, 14-group optics, it incorporates three ED (Extra-low Dispersion) glass elements and two anomalous dispersion glass elements to deliver high-contrast, high-resolution images with edge-to-edge sharpness, while effectively compensating for distortion and chromatic and coma aberrations. The lens which allows the photographer to enjoy active field photography in a wide range of outdoor applications, including scenic photography, townscape shooting and wildlife photography where its outstanding portability really comes in handy.

MTF chart information

MTF (Modulation Transfer Function) is a kind of index used to evaluate lens performance, which represents the extent of subject contrast reproduction as spatial frequency.
The MTF chart here shows the contrast on the vertical axis, and distance from the center of the image on the horizontal axis. For the spatial frequency, 10 lines/mm shows a low frequency, and 30 lines/mm shows a high frequency, resulting in the MTF graph. On the graph, the solid line represents the S direction (sagittal direction and radiation direction) MTF, and the broken line represents the M direction (meridional direction and concentric circular direction) MTF.
In general, a low-frequency MTF is proof of a clear, high-contrast lens, and a high-frequency MTF is proof of a sharp lens with high resolving power.
