PENTAX 50 mm F1.4 STAR DFA SDM AW ED Camera Lens Серебристый

Features: New-Generation, High-Performance Star-Series Lens With Large F1.4 Maximum Aperture: - This Lens Has Been Developed As A New-Generation Member Of The High-Performance Star Series — A Lineup Designed To Deliver Extra-Clear, High-Contrast Images With Edge-To-Edge Sharpness By Compensating Various Aberrations To A Minimum. After Conducting An Extensive Review Of The Star-Series Standards, Pentax Has Designed This Lens To Assure Greatly Improved Resolving Power, Looking Ahead To Its Use With More Advanced, Next-Generation Camera Bodies. It Provides Exceptionally High Imaging Performance Even At Open Aperture, In Addition To A Beautiful Bokeh (Defocus) Effect And An Outstanding Image Rendition At Close Ranges. Developed As The First Model Of The New-Generation Star-Series Lenses, This Large-Aperture: Standard Lens Boasts An Extra-Large F1.4 Maximum Aperture, Useful With Many Different Subjects In A Range Of Applications, Including Portraiture With An Effectively Defocused Background, And Handheld Shooting Of Indoor Scenes. State-Of-The-Art Optical Technology: - The Lens Is Treated With Pentax-Developed Aero Bright Coating Ii* — A Lens-Coating Nanotechnology Employing A Super-Low Refractive Film Fabrication Process. By Coupling This Advanced Lens Coating With The High-Grade, Multi-Layer Hd Coating** — Which Reduces Average Reflectance In The Visible Ray Spectrum To Less Than 50% Of Conventional Multi-Layer Coatings — This Lens Effectively Reduces Flare And Ghost Images To A Minimum Even In Demanding Lighting Conditions Such As Backlighting. By Incorporating Three Super-Low Dispersion Glass Elements And One Aspherical Element In Its Optics, It Effectively Compensates Chromatic And Spherical Aberrations, And Produces Brilliant, High-Contrast Images With Edge-To-Edge Sharpness. Since It Minimizes Distortion Even At A Focusing Distance Of Approximately One Meter, It Produces Crisp, Distortion-Free Images Over The Entire Focusing Range, From The Minimum Focusing Distance To Infinity. - A State-Of-The-Art, Pentax-Original Lens Coating Technology Developed From Nanotechnology. It Applies A Silica Aerogel Layer With A Uniform Porous Structure Over A Regular Multi-Coating Layer To Reduce Surface Reflections Across A Wide Wavelength Range And Produce Crisp, High-Quality Images. Dustproof, Weather-Resistant Construction: - Developed As An Aw (All Weather) Model, This Lens Features A Dependable Dustproof, Weather-Resistant Structure With Eight Special Seals To Prevent The Intrusion Of Water And Dust Into The Lens Interior. When Paired With A Pentax Weather-Resistant Digital Slr Camera Body, It Forms 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. Newly Developed Ring-Type Ultrasonic Wave Motor Sdm: - This Lens Features A Newly Developed Ring-Type Sdm (Supersonic Direct-Drive Motor), Which Generates As Much As 7.5 Times The Torque Of The Conventional Sdm Installed In Existing Lenses. Thanks To This Enormous Driving Power, The Lens Assures A Smooth, High-Speed Shift Of The Heavy, Multi-Element Rear Lens Group During Focusing Operation. Others: - Nine-Blade, Round-Shaped Diaphragm To Produce A Natural, Beautiful Bokeh (Defocus) Effect Up To F2.8 Aperture: Setting, While Minimizing The Streaking Effect Of Point Light Sources - A Minimum Focusing Distance Of 40 Centimeters, Effective In Capturing Images With A Defocus Effect - Electromagnetic Diaphragm-Control Mechanism,* For Flawless, High-Precision Exposure Control During Movie Recording - Sp (Super Protect) Coating To Keep The Front Surface Free Of Dust And Spots Technical Specifications: - Equivalent To 35mm Format: 76,5mm - Maximum Aperture: F1.4 - Minimum Aperture: F16 Number Of Diaphragm Blades: - Number Of Diaphragm Blades: 9 - Rounded Aperture （F1.4-2.8） - Diaphragm Control: Fully Automatic - Angle Of View: 47゜(When Attached To Pentax 35mm Slr Cameras) - Construction: 15 Elements In 9 Groups - Smallest Object Distance/Magnification: 0.4m / 1.3 Ft - Magnification: 0.18x - Filter Size: 72mm - Mount: Kaf4 - Weight: Approx. 910g (With Hood Approx. 955g) - Dimensions (Length X Diameter): Approx. 106 Mm X 80 Mm Kit Content: - Lens Hood: Ph-Rbb72 (Provided) - Lens Cap: O-Lc72 (Provided) - Lens Case: S120-140 (Provided) - Lens Mount Cap K (Provided) Special Features: - Hd Coating - Aero Bright Coating - Sp (Super Protect) Coating - Aw (All Weather Resistant) - Sdm - Ultrasonic Motor - Quick-Shift Focus System
