The camera has many SLR-like handling features — dual control wheels for aperture and shutter speed, manual focus (focus-by-wire), zoom rings and a flash hot shoe. It is among the largest non-SLR cameras, and is positioned at the high end of the bridge-camera market. Zooming while recording movies is supported since the zoom is manual.
The focus itself may be adjusted in a variety of ways. Larger view cameras and the like slide the lens closer or further from the film plane on rails; on smaller cameras, a focus ring on the lens is often rotated to move the lens elements by means of a helical screw. Other systems include levers on the lens or on the camera body.

The longer the extension tube, the closer the lens can focus. Correspondingly, the amount of light and depth of field will be reduced. [3] On modern cameras using auto exposure the decrease in exposure is corrected for by the camera, but when not using auto exposure this has to be calculated and taken into account when setting exposure.
