The 35mm camera comes with a fixed zoom lens. The zoom range is from 35 mm to 90 mm. The largest available aperture is f/3.5 (35 mm) and f/7.7 (90 mm). The lens is focused by autofocus. The focus lock can be used to fix the set distance. The closest focusing distance of this lens is 75 cm at 35 mm. In the telephoto range, you have to keep a distance of 90 cm.
The 35mm photo camera has a built-in light meter. It is designed for an ISO range of 25 to 3200. The film speed is determined by the DX code. The correct exposure is set automatically by the camera.
However, there are some exposure modes. These can be selected at the touch of a button and are shown via a display on the top of the camera. For instance, the camera comes with an “Auto Stand-by Zoom”. The ASZ mode is switched on via a button and activated when you put your eye to the viewfinder. Depending on the distance to the subject, the camera automatically adjusts the zoom. An exposure mode for landscape shots is available, as is a continuous shooting mode for fast subjects. Creative pictures are possible with the double exposure mode.
The self-timer makes group pictures and selfies very easy. After pressing the shutter button, you have ten seconds to get into position. If desired, the camera can also take two pictures in a row. Shooting is less stressful with the optional RC-2 infrared remote.
There is a built-in flash for taking pictures in low light. The flash comes with an automatic for red-eye prevention. There is also a fill-in flash mode and a mode for portraits at night. Of course, the flash can also be turned off, for example for landscape shots. The flash range is 6 meters at ISO 100 in wide-angle.
