A circular aperture that makes the most of the beautiful bokeh, a dust-proof and drip-proof structure are used, and the AF method is exclusively for SDM (AF using an ultrasonic motor inside the lens). It is a medium telephoto single focus lens with an extremely bright large aperture with an open F value of 1.4, which is equivalent to 84.5 mm in 35 mm format, and 84.5 mm in 35 mm format. Aero Bright Coating The newly developed Aero Bright Coating achieves excellent reflection performance in a wider wavelength range.
The transmittance is greatly increased, and the occurrence of flare and ghosts that affect image performance is further reduced. Beautiful and soft bokeh The latest optical design that takes into consideration the bokeh and the adoption of a circular aperture (up to F2.8) realize a beautiful and soft bokeh that takes advantage of the shallow depth of field unique to large-diameter lenses. Dust-proof / drip-proof structure By sealing each part, we have adopted a dust-proof / drip-proof structure that prevents water droplets and dust from entering the inside of the lens. After focusing with the quick shift focus system AF, if you turn the focus ring as it is, it immediately shifts to manual focus.
It can be done smoothly without the hassle of switching operation. SP (Super Protect) coating A special water- and oil-repellent coating is used on the front of the lens. It is effective in protecting the lens surface because it is hard to get dirty and easy to remove. Digital-only design The special design optimized for the characteristics of digital images suppresses the occurrence of ghosts and flares. In addition, the image circle is specialized for the size of the image sensor, achieving a compact and lightweight body size for a large-diameter type.Accessories Hood, lens cap, lens mount cap, lens case Specifications Lens type Telescopic single focal length (35mm format equivalent) 55mm (84.5mm) Open aperture value F1.4 Minimum aperture F22 Angle angle 28.6 ° Lens configuration 8 groups 9 Number of aperture blades 9 pieces Shortest shooting distance 0.45m Maximum shooting magnification 0.173x Filter diameter 58mm Maximum diameter x Length 70.5x66mm Weight (weight) 375g Compatible converters A1.4X-S, A2X-S, HDPENTAX-DAAFREARCONVERTER1.4xAW Open aperture is from F2.4.
