ЗВЕЗДА НА ПОДИУМА
Large aperture Star series lens ideal for portraits
This lens features high resolution for sharp, crystal-clear images of subjects and a smoothly connected out-of-focus (bokeh) softness. This is a medium telephoto lens that is ideal for portraits. The lens uses Anomalous Dispersion Glass for reducing color blurring and enabling images with high contrast and sharpness. It also uses the „Aero Bright Coating,“ which features higher transmissivity than conventional coatings for delivering high image quality with unparalleled sharpness and a minimum of flare. The lens uses a round iris diaphragm for providing natural out-of-focus (bokeh) effect and has a dust-resistant and drip-proof construction. The AF system is for SDM (AF using internal lens ultrasonic motor) only (Note 1).
Функции и характеристики
The newly developed Aero Bright Coating provides exceptional reflection performance over a wide wavelength range. This enables a significantly higher transmissivity for a substantial reduction in flare and ghosting, which adversely affect imaging performance
This is a medium telephoto single focal point lens equivalent to 84.5mm in the 35mm film format, and it includes a large aperture with an extremely bright open F value of 1.4. This lens is ideal for portrait and other photography.
The newest optical design and a round iris diaphragm (up to F2.8) were developed with special attention to providing a natural, soft out-of-focus (bokeh) effect with a shallow depth of field that is only possible with large aperture lenses.
The various lens components have been sealed for enabling a dust-resistant and drip-proof construction that prevents the entry of water and dust into the lens.
If you turn the focus ring after focusing by the AF, focusing instantly switches to the manual focus. This enables smooth focusing operations without the need for a switching operation.
A special coating is used on the front lens for repelling water and oils. This enables any water and oils on the lens to be easily removed for effective protection of the lens surface
Note 1: The autofocus is compatible with SDM only. The compatible models are the K-7, K20D, K200D, K-x, K-m, K10D (firmware version 1.30 or later), and K100D Super. If you have K10D with firmware version 1.20 or earlier, download the compatible firmware 1.30 from this website and install it to your camera. If attached to a non-SDM K100D or istD series camera, focusing is performed using the manual focus
