Features:
1. A new generation of high-performance ★ (star) mirror for the pursuit of ideal image quality

This lens is a fuselage that is expected to further evolve in the future, especially as a new generation of ★ (star) lens that realizes a significant increase in image power. Various aberration corrections have been performed to achieve a clear and sharp height from the center to the edge. Descriptive ability. High resolution performance can be obtained when the aperture is fully opened, and the beauty of the blur and the performance of close-up drawing are improved, so that you can enjoy three-dimensional drawing. With the bright full aperture value F1.4, in addition to portrait photography, it can produce background blur effects in indoor handheld photography, landscape photography and other occasions, and can obtain bright viewfinder images that drive the shooting mood.

2. Use new optical technology

　　 This lens uses 3 abnormally low dispersion lenses that can achieve high chromatic aberration reduction effects in the optical system. At the same time, an aspheric lens is used to compensate for spherical aberration, coma aberration and curvature of field. When the aperture is fully opened, it can achieve clear and high-contrast drawing performance from the center to the edge. Even the aberration of 4m from the subject can be corrected, and the entire area from infinity to close-up distance can be drawn smoothly with less distortion. In addition, through the use of high-performance multi-layer coating "HD Coating"*1 that can reduce the average reflectance in the entire visible light region to about 50% or less of conventional coatings, it can effectively suppress the occurrence of severe shooting conditions such as backlighting. Ghosts and flare. Note 1: "HD" is an abbreviation for High Definition.

3. Equipped with a newly developed ring-shaped SDM ultrasonic motor

In order to achieve high image quality in the entire range from close range to infinity, multiple sets of heavier rear lens group moving focus drive methods are required. Therefore, it is equipped with a newly developed ring-shaped SDM ultrasonic motor, which can play a large scale. HD PENTAX-D FA★ 50mmF1.4 SDM AW｣'s SDM motor has 1.3 times the torque, realizing high-speed and smooth autofocus.

4. Dust-proof and drip-proof structure

　　The inside of the lens adopts the dust-proof and drip-proof structure "AW (All Weather)", which is difficult to penetrate by water droplets and dust, and the 8 parts of the lens are sealed. When used in combination with our interchangeable lens digital camera body that adopts a dust-proof and drip-proof structure, it improves the durability and reliability in rainy and foggy places where water may be splashed.

5. Other
①In order to suppress the light when shooting point light sources, 9 circular aperture blades with a large aperture of F2.8 that can shoot soft blur effects are adopted.
②Adopt an exterior design that is easy to rotate the focus ring during manual focus and has excellent handheld performance
③Electromagnetic diaphragm mechanism that can control the exposure smoothly and with high precision in the video mode Note 2
④The lens adopts SP (Super Protect) coating which is not easy to contaminate dust
Note 2: Supported models: K-1 Mark II, K-1, K-3 II, K-3, KP, K-70, K-50, K-S2, K-S1.

Description:
This lens aims to give full play to its performance even when it is used in interchangeable lens digital cameras with higher image quality and higher performance in the future. It is the second of a new generation of fixed-focus star lens with a large-caliber revised specification. Medium and telefocus fixed focus lens. In pursuit of the high image quality of products that do not rely on image sensors and image processing, the ability of the lens can be felt, from the moment the photographer looks through the optical viewfinder, the high-quality viewfinder image can be used to confirm the subject in real time in detail , So as to enjoy the fun of shooting.

In order to achieve excellent depiction performance consistent with the name of the new generation of high-performance star mirrors, this lens does not hesitate to use high-performance ultra-low dispersion lenses and aspherical lenses to further correct various aberrations, especially on the axis The chromatic aberration is suppressed, and the purple fringing that is easy to appear in backlight photography can also be effectively suppressed. In addition, for the aberrations that are important for portrait photography, the effect is close to 0% at 4m. In addition, it is equipped with a newly-developed ring-shaped ultrasonic motor that realizes high-speed and smooth operation during autofocusing, and an exterior design with excellent handheld performance during manual focusing. It is a high-quality, enjoyable shooting product.
