This operating manual applies to all of the smc PENTAX FA and FA J lenses. Please also read your camera's operating manual. * In this manual, the "smc PENTAX - FA lens" is referred to as "FA lens" and the "smc PENTAX - FA J lens" as the "FA J lens". [. . . ] * For the FA 43mm f/1. 9 Limited lens, attach the lens cap to the hood. The lens cap cannot be attached directly to the front of the lens. 12 Focusing 15 10 3 86 2 1. 5 ft m 50 A 22 16 11 8 5. 64 2 82 14 To switch between autofocusing and manual focusing, use the camera's focus mode lever. For details, refer to your camera's instruction manual. * For non-autofocus cameras, use manual focusing. Autofocusing Press the shutter button halfway to autofocus. * During autofocusing, the focusing ring rotates so do not touch it. Manual focusing Turn the focusing ring as shown in the illustration. 13 Setting autofocus Push the focusing ring forward until you can see AUTO FOCUS. * When the lens is set for autofocus, the focusing ring locks. Setting manual focus Pull the focusing ring until AUTO FOCUS is hidden. Turn the focusing ring to focus manually. FA lenses With FA lenses, shift the focusing ring forward or back to switch between autofocus and manual focus. 14 * If your camera has a KAF2 mount, you can still switch between autofocus and manual focus with the lens focusing ring even when the camera has been set to autofocus. * If you have a camera (such as the SF-series) having a KAF mount, set both the camera and lens focus mode switch to the same setting. If the camera is set to autofocus [AF single] and the lens is set to manual focus, you cannot take a picture until the camera's focus indicator lights. * If you use a camera which does not have autofocus, focus manually. * The telephoto lens' focusing ring stops turning at slightly past the infinity symbol. This is because, the point of focus changes depending on the temperature, and sometimes the focus is achieved beyond the infinity symbol. * Even when focusing at infinity, always look through the viewfinder to make sure the subject is in focus. * When the lens is set for manual focus, the focusing ring can continue to turn even past the minimum focusing distance or infinity mark. Setting the Aperture [A (Auto) Lock Switching] 15 15 8 ft 10 3 2 m 22 16 8 15 8 ft 10 3 2 m 22 16 8 50 22 16 11 8 5 . 6 4 50 A 5. 6 4 2. 8 2 1. 4 A 22 16 11 8 To set the aperture ring to A [Auto], hold down the Aperture A-lock button and align the A index with the white-line index. To set the aperture ring to another setting, hold down the Aperture A-lock button and turn the aperture ring. * If your camera has a K mount with no lens information contacts, set the aperture ring to any aperture except A. 16 About the Zoom Lens Aperture Zoom lenses whose maximum aperture varies depending on the focal length have a [Minimum length] aperture index for the shortest focal length and a [Maximum length] aperture index for the longest focal length. To set the aperture to A [Auto], turn the aperture ring to the white [Short focal length index] at the center (regardless of the focal length) as shown in the illustration. For the longer focal lengths, if you want to set an aperture other than A, align the aperture ring with the long focal length's aperture. For example, with a 28-105mm zoom lens set to 105mm, set the f/8 aperture by aligning the aperture ring's f/8 to the [Long focal length aperture index] mark on the left of the white index. * When setting the aperture manually at a middle focal length, use the aperture index for the short and long focal lengths as a reference. 17 Apertures and Click Stops Certain lenses have a white dot next to the maximum aperture. [. . . ] The aperture is controlled at the A [Auto] position. 35 Includes tripod mount. Figures in ( ) indicate the thread diameter of the front ring of Filter. Max.
