Nastavitev
Pritrditev objektiva
- Prepričajte se, da sta tako fotoaparat kot objektiv izklopljena.
- Odstranite zadnji pokrovček objektiva in pokrovček ohišja fotoaparata.
- Align the red mounting index mark on the lens barrel with the corresponding mark on the camera body.
- Vstavite objektiv v bajonet fotoaparata in ga zavrtite v smeri urinega kazalca, dokler se ne zaskoči. Ne pritiskajte na objektiv na silo.
Odstranjevanje objektiva
- Prepričajte se, da je kamera izklopljena.
- Medtem ko držite pritisnjen gumb za sprostitev objektiva na ohišju fotoaparata, zavrtite objektiv v nasprotni smeri urinega kazalca, dokler se ne ustavi.
- Previdno odstranite objektiv iz ohišja fotoaparata.
- Zadnji pokrovček objektiva namestite na objektiv, pokrovček ohišja pa na fotoaparat, da ju zaščitite pred prahom in poškodbami.
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.

Upravljanje objektiva
Osredotočanje
- Samodejno ostrenje (AF): Set the AF/MF switch on the lens to 'AF'. The lens utilizes a Supersonic Direct-drive Motor (SDM) for quiet and fast autofocus.
- Ročno ostrenje (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.
Nadzor zaslonke
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.
Vremensko odporna konstrukcija
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.

Vzdrževanje
Čiščenje leče
- Elementi leče: 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.
- Ohišje objektiva: Ohišje objektiva obrišite z mehko, suho krpo. Ne uporabljajte organskih topil, kot sta razredčilo za barve ali benzen.
- Prah: Za odstranitev prahu s površine leče uporabite puhalnik.
Shranjevanje
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.
Odpravljanje težav
- Samodejno ostrenje je počasno ali nenatančno:
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.
- Fotoaparat ne prepozna objektiva:
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.
