1. Open F value 1.4, new-generation high-performance star lens ) series standards, and assuming that camera bodies will further evolve in the future, we have developed a new-generation star lens that achieves a significant improvement in resolution. Extremely high resolution performance is obtained even from the maximum aperture, and in addition, the beauty of the bokeh effect and the descriptive performance at close distances are also enhanced. This product, the first of the new-generation star lenses, has an extremely bright maximum aperture of F1.4, and is suitable for shooting a variety of subjects, such as portrait photography and indoor handheld photography, making use of the bokeh effect of the background. It is a wide large-aperture standard lens. 2.Using the latest optical technology Adopts a proprietary nanotechnology "Aero Bright Coating II (Note 1)" that achieves excellent low-reflection characteristics through an ultra-low refractive index film formation process. increase. In addition, when used in combination with the high-performance multi-coating "HD Coating Note 2," which suppresses the average reflectance in the visible light range to approximately 50% or less compared to conventional models, ghosts and flares can be reduced even under harsh lighting conditions such as backlight. effectively suppresses the occurrence of In addition, the use of three abnormally low-dispersion glass elements and one aspherical lens element effectively compensates for chromatic and spherical aberrations, resulting in clear, high-contrast imaging performance from the center to the periphery. I'm here. Furthermore, distortion is corrected to almost zero at a subject distance of approximately 1m, enabling sharp images with little distortion over the entire range from infinity to the shortest shooting distance. Note 1: By using silica airgel, which has homogeneous air gaps, as the main component, it achieves an excellent anti-reflection effect over a wide wavelength range and achieves a high level of clear image quality. lens coating technology. Note 2: "HD" stands for High Definition. 3.Dust-proof and drip-proof structure As an "AW (All Weather)" type with a dust-proof and drip-proof structure that prevents water droplets and dust from entering the inside of the lens, sealing is applied at eight locations throughout. Combined with our digital single-lens body, which has a dust-proof and drip-proof structure, it achieves improved durability and reliability even in rain or fog, or in locations subject to water splashes. 4. Newly developed ring-shaped SDM ultrasonic motor A newly developed ring-shaped SDM ultrasonic motor is used to drive the autofocus. It can generate approximately 7.5 times the torque of the motor used in the SDM of conventional DA* lenses, enabling the rear lens group, which has a large number of lenses and is heavy to move during focusing, to operate smoothly at high speed. 5.Other 9-blade circular diaphragm that suppresses the streak of light when shooting with a single point light source and provides soft bokeh up to F2.8 2Achieves a minimum shooting distance of 40cm, which is convenient for taking advantage of bokeh 3Video mode Electromagnetic diaphragm mechanism that enables smooth and highly accurate exposure control 4 The front surface of the lens is coated with SP (Super Protect), which is highly resistant to dirt.
Description by manufacturer
Best-in-class standard single focal length lens F1.4 large aperture single focal length lens that pursues high image quality PENTAX quality control Outstanding rendering performance worthy of being called a "new-generation star lens"
A familiar standard lens turns into something special.


Aberration is effectively reduced, and excellent resolution is achieved from the maximum aperture of F1.4. Aiming for ideal image quality, various aberrations are corrected to the utmost limit, and sharp and clear images from the center to the periphery are pursued. Big changes this time. In particular, we have achieved a significant improvement in resolution. You can get natural ball bokeh without emphasizing the edge of the light source. It also suppresses the effect of vignetting on the blurred image at the periphery of the image, making it possible to actively take advantage of ball bokeh. You can expect it to be useful in a variety of scenes, such as shooting flowers and table photos. PENTAX interchangeable lenses undergo strict quality control not only at the design stage, but also at the manufacturing stage. For all completed lenses, we measure resolution, contrast, color tone, various aberrations, etc. using our proprietary measuring instruments, and carry out objective numerical evaluations. We strive to maintain stable quality by, for example, readjusting lenses that deviate even slightly from our strict standards.


All PENTAX digital SLR cameras in the K series are equipped with in-body image stabilization that expands the limits of hand-held shooting. It has a dustproof and splashproof structure that is strong enough for outdoor shooting and can be used reliably even in the harshest conditions. Eight locations are sealed. By making full use of coating technologies such as the newly developed Aero Bright Coating II and HD Coating, the occurrence of ghosts and flares is suppressed even in backlight, enabling clear, high-contrast images to be obtained. It can generate about 7.5 times the torque of the motor used in the SDM of conventional DA* lenses, enabling the rear lens group, which is heavy and has a large number of lenses, to operate smoothly at high speed.
