“Interchangeable lens for K mount digital single lens reflex camera
Product name: HD PENTAX-D FA ★ 50 mm F 1.4 SDM AW (tentative name)
- K mount adopted, covering image circle of 35 milf size image sensor
- A newly developed ring type SDM (ultrasonic motor) that realizes high-speed and quiet AF
- Adopt AW (dust-proof and drip-proof) structure to suppress invasion of rain particles and dust under harsh photographic environment
- The shortest shooting distance of 0.4 m is achieved
- Release date: scheduled for spring around 2018
By touching the professional type,
- Instead of mechanical iris type, electromagnetic iris
- The number of diaphragm blades is 9
- The movement of the ring type SDM is exactly the same feeling with Canon’s USM
- The lens hood has Penta’s traditional handicraft, detachable PL operation window cover
- The weight is slightly heavier than Sigma’s Art 50 mm F 1.4
- Filter size is 72 mm
- The height of the focus peak, and the flow to the out-focus part is very natural
- When previewing the chrome-plated part of the camera at the shortest shooting distance, no purple fringe at the time of opening is shown
- Because it was daytime, I was sorry that I could not try to see how the point source of the night looks ( I wanted to see sagittal coma flare · haha )
Then, first from the mounting part. Aperture link lever is not attached…”
