NEW “HD” PENTAX-FA Limited

NEW “HD” PENTAX-FA Limited series!

Three HD PENTAX-FA Limited interchangeable lenses for use with K-mount SLR cameras, featuring the latest HD coating and round-shaped diaphragm

RICOH IMAGING COMPANY is pleased to announce the launch of three HD PENTAX-FA Limited interchangeable lenses for use with PENTAX K-mount SLR cameras. Featuring the latest HD coating and a round-shaped diaphragm, these new lenses boast much-improved imaging performance to deliver distinctive, well-defined images in combination with a K-mount camera body, while sporting an attractive exterior design.

Developed based on the FA Limited Lens series — renowned for their meticulousness in every detail, from outstanding image rendition to high-quality, machined aluminum bodies — these new lenses are designed to assure even better optical performance than the original Limited-series models. This is all a part of PENTAX’s attempt to reach a level of performance that can’t simply be measured in numerical values. Along with the distinguished qualities of the HD FA Limited series — outstanding description of texture, fine reproduction of gradation in highlight areas, faithful reproduction of details, and natural reproduction of the bokeh (defocus) effect — they have been treated with the PENTAX-original HD coating, which assures much higher light transmittance than conventional multi-layer coatings. They deliver sharp, clear images free of flare and ghost images, even under such demanding conditions as backlight. They also feature a completely round-shaped diaphragm to produce a natural, beautiful bokeh effect in the foreground and background.

Main features of the HD PENTAX-FA Limited lenses (common to all three models)

1. High-grade HD coating for exceptional image rendition

The three new lenses are treated with the PENTAX-original HD coating.* Compared with conventional multi-layer coatings, this high-grade coating assures higher light transmittance and lower reflectance to deliver sharp, clear images free of flare and ghost images, even under such adverse lighting conditions as backlight. It elevates the imaging performance of these new lenses a further step up.

* HD stands for High Definition.

2. Round-shaped diaphragm for beautiful bokeh effect

All lenses feature a completely round-shaped diaphragm, which produces a natural, beautiful bokeh (defocus) effect in the images captured, while optimizing the imaging performance of the distinctive Limited Lens-series optics contained within.

3. Acclaimed Limited Lens-series quality for distinctive visual rendition and premium appearance

While inheriting the design concept of the Limited Lens series, these lenses were designed through a series of mechanical and numerical evaluations, as well as human assessment of test-shooting samples, to deliver an image rendition unmatched by other models. The barrel, hood and cap are all made of high-grade aluminum, meticulously machined for an attractive appearance and beautiful texture. The HD PENTAX-FA 43mm F1.9 Limited features a mount pointer made of a Shippoyaki (cloisonné) ware. This pointer allows the user to mount the lens to a camera body as effortlessly as other Limited Lens-series models.

4. Other features

1. SP (Super Protect) coating is applied to the front surface of each lens to repel dust and stains.
2. Black models are marked with a serial number starting with 0000001; silver models start with 1000001.
3. The aperture ring has been retained so that the user can still use a variety of functions featured in K-mount film-format cameras.

HD PENTAX-FA 35mm F2 announced!

HD PENTAX-FA 35mm F2 announced!

A single-focus, wide-angle lens for use with K-mount digital SLR cameras, featuring latest lens coatings to further upgrade image quality

RICOH IMAGING COMPANY, LTD. is pleased to announce the launch of the HD PENTAX-FA 35mm F2. Despite its compact dimensions, this high-performance, wide-angle lens is designed to cover the full-frame image circle of PENTAX K-mount digital SLR cameras.

 

The development of this new lens was based on the smc PENTAX-FA35mm F2 AL — a very popular multi-purpose, wide-angle lens used on film-format SLR cameras — while conducting a thorough review of lens coatings.

The high-grade, multi-layer HD Coating has been applied to the optical elements to produce high-contrast images with edge-to-edge sharpness and free of flare and ghost images; the highly stain-repellent SP Coating has been applied to the front surface to improve the lens’s usability in outdoor locations. The exterior has been totally redesigned to match the design of latest PENTAX K-mount digital SLR models, while its compact, portable body makes it a perfect everyday-use lens.

*Please apply the latest updater of Digital Camera Utility 5 when you handle images taken by this lens on Digital Camera Utility 5. In case the software version is old, the name of this lens can not be displayed correctly. Digital Utility 4 and below can not display the name of this lens correctly.

 

Lens construction

 

Comparison of anti-backlight performance

Even under adverse conditions such as a strong light source in the image field, HD Coating effectively reduces the generation of ghost images, compared to conventional multi-layer coatings.

 

Comparison of transmissivity

Although both the old and new FA 35mm F2 lenses feature a simple lens construction, the HD PENTAX-FA 35mm F2 assures higher transmissivity as a whole, because its HD Coating-treated lens surfaces have superior anti-reflectance performance.

 

Main Features
HD Coating to enhance imaging power

After a thorough review of the lens coatings applied to the popular smc PENTAX-FA 35mm F2AL, PENTAX applied the latest HD Coating* to this lens. Compared to conventional multi-layer coatings, this high-performance, multi-layer coating reduces average reflectance and improves light transmittance to deliver extra-clear, high-contrast images free of flare and ghost images, even in demanding lighting conditions such as backlighting.

* HD stands for High Definition.

SP Coating to repel stains

Applied to the lens’s front surface, the SP (Super Protect) Coating is highly repellent to water and grease, making it easy to wipe off any stains. This frees the photographer from worries in outdoor photography.

New exterior design to match latest digital SLR models

While retaining the overall size of the original smc PENTAX-FA 35mm F2AL, this lens features a totally new exterior design, similar to that of the latest DA- and D FA-series lenses. This new appearance makes this single-focus lens a perfect partner for latest K-series digital SLR models. Since this lens retains the aperture ring, it also accommodates many of the functions provided by film-format SLR cameras and older K-mount digital SLR models, making it possible to enjoy photography using a greater range of cameras.

Easy-to-use standard lens

When mounted on a PENTAX digital SLR camera body, this lens provides a moderately wide 35mm angle of view with a full-frame model, or a standard 53.5mm angle of view with an APS-C-format model. Since it provides a natural perspective similar to that of the naked eye, it can be used as a multi-purpose standard lens in a wide range of applications, including snapshooting, scenic photography and portraiture. It also features a minimum focusing distance of 0.3 meters.

Compact, portable design

Weighing approximately 193 grams and measuring a mere 44.5 millimeters in length, this lens has been designed to be extremely compact and highly portable for carefree photography at any location and on every occasion.

Hybrid aspherical optical elements

The lens incorporates hybrid aspherical optical elements to effectively compensate for various aberrations. Thanks to these elements, it delivers extra-clear, high-contrast images from the minimum focusing distance to infinity, and edge-to-edge sharpness even at open aperture.

But… There is a mistake here technically. Object has to be in same dimensions on the frame for 100% right comparison. For example if we use 1 m -lens to object- distance for a 50 mm lens, should be ~0.86 m for a 43 mm. Otherwise this technical mistake effects bokeh dramatically!

Also a 50 mm lens gives more smooth bokeh -than a 43 mm lens- on the background thanks to its +7 mm tele magnification factor. So would be a mistake to say: “HD PENTAX-D FA★ 50mm F1.4 SDM AW is better than the smc PENTAX FA 43mm F1.9 Limited about bokeh quality.” etc.
