Lens DT 18-55mm F3.5-5.6 SAM II (Supplied with ILCA68K) Focal length: Equivalent 35 mmformat focal length*1: 27 mm - 82.5 mm Lens groups/elements: 7/8 Angle of view*1: 76° - 29° Minimum focus*2: 0.25 m (0.82 ft.) Maximum magnification: 0.34 Minimum f-stop: f/22 - f/36 Filter diameter: 55 mm Dimensions (max. diameter × height): Approx. 71.6 mm × 69 mm (Approx. 2 7/8 inches × 2 3/4 inches) Mass: Approx. 222 g (Approx. 7 7/8 oz.) *1 The values for equivalent 35mmformat focal length and angle of view are based on Interchangeable Lens Digital Camera equipped with an APS-C sized image sensor. *2 Minimum focus is the shortest distance from the image sensor to the subject. • This lens is equipped with a distance encoder. The distance encoder allows more accurate measurement (ADI) by using a flash with ADI functionality. • Depending on the lens mechanism, the focal length may change with any change of the shooting distance. The focal length assumes the lens is focused at infinity. Specifications • The infinity position provides for some adjustment to compensate for focus shift caused by change in temperature. To shoot a subject at infinite distance in MF mode, use the viewfinder and set focus. On focal length The picture angle of this camera is narrower than that of a 35 mmformat camera. You can find the approximate equivalent of the focal length of a 35 mm-format camera, and shoot with the same picture angle, by increasing the focal length of your lens by half. For example, by using a 50 mm lens, you can get the approximate equivalent of a 75 mm lens of a 35 mm-format camera. On image data compatibility • This camera conforms with DCF (Design rule for Camera File system) universal standard established by JEITA (Japan Electronics and Information Technology Industries Association). • Playback of images recorded with your camera on other equipment and playback of images recorded or edited with other equipment on your camera are not guaranteed.
