HD PENTAX-FA35mmF2: A single-focus, wide-angle lens for use with K-mount digital SLR cameras, featuring latest lens coatings to further upgrade image quality 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-FA35mmF2AL — 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. HD Coating to enhance imaging power After a thorough review of the lens coatings applied to the popular smc PENTAX-FA35mm F2AL, PENTAX applied the latest HD Coating* to this lens. Compared to conventional multilayer 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-FA35mmF2AL, 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 APSC-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.
Large F2.8 maximum aperture Despite its compact dimensions, this ultra-wide-angle zoom lens provides a focal length of 11 to 18 millimeters (equivalent to 17mm to 27.5mm in 35mm format) to produce magnificent, dynamic images. Since its maximum aperture is fixed at F2.8 over the entire zoom range, it delivers sharp, bright images of scenes with starry skies. Thanks to a minimum focusing distance of 0.3 meters, the lens also lets the photographer capture true-to-life close-up images by emphasizing the depth of field with an effectively defocused background. HD Coating to enhance imaging power This lens features high-grade, multi-layer HD Coating,* which reduces the average reflectance in the visible ray spectrum to less than 50% of conventional multi-layer coatings. It effectively minimizes flare and ghost images even in demanding lighting conditions such as backlighting. Ideal design optimized for photography of landscapes and star-lit scenes The unique Focus Clamp Mechanism allows the photographer to lock the lens’s focal point, even when the focus ring is rotated. This improves the lens’s operability in photographing such subjects as landscapes and star-lit scenes, which demand high-precision focusing during extended exposures. It also has special features for improved operability and versatility in outdoor shooting, such as a space for wrapping heating wires around the lens barrel to prevent dew condensation, without affecting focus-ring operation; and a metallic frame structure to more effectively transmit the heat of the heating device to the lens. Dustproof, weather-resistant construction Developed as an AW (All Weather) model, this zoom lens features a dustproof, weather-resistant construction 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, this assures a highly durable, reliable digital imaging system that performs superbly in demanding shooting settings — even in rain or mist, or at locations prone to water splashes. Other features - Smooth, quiet AF operation using a DC motor - Round-shaped, nine-blade diaphragm to produce a natural, beautiful bokeh (defocus) effect while minimizing the streaking effect of point light sources - Quick-Shift Focus System to provide an instant shift to manual-focus operation after locking the subject in focus during AF operation by pressing the shutter-release button halfway down; usable at any time during AF operation - SP (Super Protect) Coating to keep the lens’s front surface free of dust and stains
Pentax smc DA* 300mm f/4 ED [IF] SDM De smc DA*-telelens van de nieuwe generatie high performance ultrasone objectieven. Uitzonderlijke optische kwaliteit Ultrasone optiek voor een ultrasnelle en ultrastille scherpstelling Stof- en spatwaterbestendige behuizing ‘Quick-Shift’ uitschakelbaar scherpstelsysteem SP (Super Protect) bescherming tegen water en stof De objectieven uit het smc DA*-gamma zijn niet alleen van uitzonderlijke kwaliteit, maar zijn bovendien uitgerust met een ultrasone motor die hen absoluut geluidloos en ontzettend snel maakt. Voor een betere contrastweergave, een grotere netheid – ook aan de rand van de lenzen – en een bijzonder gedetailleerde en fijne weergave kregen de lenzen een specifieke ED- en asferische behandeling. De ultrasone aandrijvingen van de DA*-lenzen werken extreem stil en snel en staan garant voor een perfecte scherpstelling. Beide objectieven zijn dankzij de speciale afdichtring vocht- en stofbestendig. Het voorste lenselement werd met een SP ‘Super Protect’ fluorietlaag behandeld die stof vingerafdrukken afstoot waardoor het schoonmaken van de lens heel wat vlotter verloopt. Met het ‘Quick-Shift’-systeem van PENTAX kan de gebruiker de scherpstelling handmatig bijstellen, nadat de informatie eerst in het geheugen werd opgeslagen, zonder dat de autofocusmodus moet worden uitgeschakeld.
