19. Has a built-in focus motor

The focus motor moves the lens in order to autofocus. For system cameras, having a focus motor in the camera's body allows you to use a wide range of lenses, including lenses which do not have their own focus motor. For compact cameras, a focus motor is usually built-in.

28. has an optical viewfinder

An optical viewfinder (or OVF) allows the photographer to compose a shot while seeing exactly what the lens sees. There is no time lag and they require no power - as opposed to electronic viewfinders which can drain battery life. They are also better in low light situations.

30. shoots raw

A raw image file contains minimally processed data from the image sensor. Raw files are so named because they are not yet processed and therefore are not ready to be printed or edited with a bitmap graphics editor.

31. flash sync speed

Flash synchronization is defined as the firing of a photographic flash coinciding with the shutter admitting light to the image sensor. In general, faster flash sync speeds are better if the photographer needs to flash-fill subjects that are backlit and wants to avoid motion blur, or wants to increase depth of field by using a high aperture.

33. exposure time

When the camera shutter is open for a long time, more light is absorbed by the sensor. You can use this slow shutter speed to produce vivid night time photography, or capture the trajectory of moving objects such as motorway traffic.
