Настраивать
Прикрепление линзы

- Снимите заднюю крышку объектива и крышку корпуса камеры.
- Align the red mounting index mark on the lens barrel with the corresponding mark on the camera body.
- Вставьте объектив в байонет камеры и поверните его по часовой стрелке до щелчка. Не прилагайте чрезмерных усилий.
Отсоединение объектива
- Убедитесь, что камера выключена.
- Удерживая нажатой кнопку разблокировки объектива на корпусе камеры, поверните объектив против часовой стрелки до упора.

Attaching the Lens Hood and Cap
The PH-RBH lens hood is designed to reduce flare and protect the front element. Align the hood with the front of the lens and twist until it locks securely. The O-LC58 objective cap protects the front element when the lens is not in use.

Управление объективом
Фокусировка
- Автофокус (АФ): Set the AF/MF switch on the lens to 'AF'. The lens utilizes a Supersonic Direct-drive Motor (SDM) for quiet and fast autofocus.
- Ручная фокусировка (MF): Set the AF/MF switch on the lens to 'MF'. Rotate the focus ring to adjust focus manually.
- Quick-Shift Focus System: This system allows for instant switching between autofocus and manual focus without changing the AF/MF switch position on the lens, provided the camera body supports this feature. After autofocus has locked, you can fine-tune focus manually by rotating the focus ring.
Управление диафрагмой
The lens features a fast maximum aperture of f/1.4, allowing for excellent low-light performance and shallow depth-of-field effects. The aperture can be stopped down to f/22. The 9 rounded diaphragm blades contribute to a smooth, circular bokeh (background blur) at wider apertures. Aperture control is fully automatic and managed through the camera body.
Конструкция, устойчивая к погодным условиям
The lens is equipped with a water- and dust-resistant seal, providing reliable operation in challenging environmental conditions. While resistant, it is not waterproof; avoid submerging the lens in water.

Обслуживание
Чистка линз
- Элементы объектива: The objective lens surface is treated with Pentax's Super Protect (SP) coating, a fluorine compound that repels dust, water, and grease. For cleaning, use a soft, clean lens cloth. For stubborn smudges, use a specialized lens cleaning solution applied to the cloth, not directly to the lens.
- Корпус объектива: Протрите корпус объектива мягкой сухой тканью. Не используйте органические растворители, такие как растворитель для краски или бензол.
- Пыль: Удалите пыль с поверхности линз с помощью щетки-груши.
Хранилище
When not in use, store the lens with both front and rear caps attached in a cool, dry place away from direct sunlight and extreme temperatures. Avoid storing the lens in areas with high humidity to prevent mold growth.
Поиск неисправностей
- Автофокус работает медленно или неточно:
Ensure the AF/MF switch on the lens is set to 'AF' and the camera body is also set to autofocus. Check lighting conditions; very low light can affect AF performance. If issues persist, try cleaning the lens and camera contacts. Some users have reported inconsistent SDM performance; if this occurs, contact Pentax customer support.
- Image quality is soft or blurry:
Verify that the lens is properly focused. Check your camera's shutter speed to avoid motion blur, especially in low light. Ensure the aperture setting is appropriate for your desired depth of field. Clean lens elements if smudges are present. If softness persists across all settings, the lens may require servicing.
- Объектив не распознается камерой:
Ensure the lens is securely mounted to the camera body. Clean the electronic contacts on both the lens mount and camera body with a clean, dry cloth. Power cycle the camera.
