< br>◆Super-telephoto 3x zoom lens When attached to a Pentax K-mount digital single-lens camera, a super-telephoto angle of view equivalent to approximately 230-690mm in 35mm format equivalent focal length can be obtained. The compact design allows handheld photography of long-distance subjects such as wild birds, airplanes, and sports photography, making it suitable for those looking for easy handling.

◆High rendering performance The latest lens design uses three pieces of special low dispersion (ED) glass and one piece of extra low dispersion glass, effectively suppressing spherical aberration and chromatic aberration, resulting in color blurring. This results in a high-contrast depiction with little turbulence.

◆“HD Coating” that improves depiction performance The camera uses a unique high performance multi-coating “HD Coating”. Compared to conventional multi-coatings, it has less reflection and higher transmittance, suppressing the occurrence of ghosts and flare under harsh lighting conditions such as backlighting, and achieving high contrast and clear depictions.

◆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 lens, 21 locations throughout the lens are sealed. By combining it with the PENTAX digital SLR body, which has a dust- and splash-proof structure, it improves durability and reliability even in rainy weather, fog, or locations exposed to splashing water.

◆ AF buttons in 4 locations AF buttons are arranged in 4 locations on the lens barrel at 90 degree intervals to ensure stable AF operation while holding the lens firmly regardless of its vertical or horizontal position. I'm doing it. In addition, the role of the AF button is assigned to the "Focus Preset Mode", which stores a pre-registered focus position and moves to that position, and the "AF Cancel" function, which allows you to forcibly fix the focus position during Continuous AF. It is possible. *Currently compatible model is PENTAX K-3 only. A firmware update for the camera body is required before use.

◆Other features: In-lens motor-driven AF enables quiet and smooth autofocus drive. Adopts a circular diaphragm that suppresses light beams when shooting with point light sources and achieves soft bokeh. AF by limiting the focus range.
