Knowing camera parts names makes manuals, tutorials, and gear talk much easier to follow. Most DSLR and mirrorless cameras share the same core parts, though their positions vary by model. This guide walks through the front, top, and back of a typical camera body.
Front of the Camera
- Lens mount: the metal ring where the lens attaches. Different brands use different mounts.
- Lens release button: the small button you press to remove the lens.
- Grip: the raised area your right hand holds.
- Sensor: behind the mount, the part that records the image. It is visible when the lens is off, and should be handled very carefully.
- Autofocus assist lamp or self timer light: a small light that helps focus in dim scenes or counts down the timer.
- Mirror: in a DSLR, the angled mirror behind the lens that sends light to the viewfinder.
Top of the Camera
- Shutter button: press halfway to focus and fully to take the picture.
- Mode dial: selects exposure modes such as manual, aperture priority, shutter priority, and automatic.
- Command dials: wheels that change settings like aperture and shutter speed.
- Power switch: turns the camera on and off.
- Hot shoe: the mounting slot on top for flashes, microphones, and other accessories.
- Top display: on some bodies, a small screen that shows settings.
Back of the Camera
- Viewfinder: the eyepiece you look through. It is optical in DSLRs and electronic in many mirrorless cameras.
- Rear screen (LCD): shows menus, live view, and playback. Some tilt or flip out.
- Menu button and directional pad: used to move through menus.
- Playback button: shows saved photos.
- Autofocus point selector: a joystick or pad that moves the focus point.
- Card slot door: covers the memory card slot, often on the side.
The Lens Parts
- Front element and filter thread: the glass at the front, with threads for filters.
- Focus ring: turns to focus manually.
- Zoom ring: on zoom lenses, changes focal length.
- Aperture ring: found on some lenses, adjusts the opening directly.
- Switches: usually autofocus and manual toggles, and sometimes stabilization.
- Lens hood: a shield on the front to reduce flare and protect against bumps.
FAQ
Do all cameras have the same parts?
Most share the basics, but button layouts and names vary. Compact cameras may lack a mount and hot shoe, and many mirrorless cameras have no mirror.
What should I learn first?
Begin with the shutter button, mode dial, command dials, and focus point selector, because those are used on every outing.
The Short Version
Think of the camera in three zones: the front with mount and grip, the top with shutter button and dials, and the back with screen and menu controls. Check your manual for exact positions on your model.
