Set The Depth Of Field On A Wide Angle Zoom Lens

A wide-angle zoom lens.


Wide-angle zoom lenses offer great performance for a variety of different photography styles, and proper control over depth of field will unlock their true potential.


Instructions


Digital SLR Cameras and Modern 35mm Cameras


1. A 35mm SLR camera body, minus a lens.


Attach the wide-angle zoom lens to your camera, ensuring it is firmly in place.


2. A digital SLR mounted on a tripod for rigidity.


Frame your shot. A tripod will help if you are aiming to capture a very large depth of field with a slower shutter speed.


3. A camera dial, used to change shooting mode.


Use your camera's aperture priority mode (A) or manual mode (M). Aperture priority will leave the camera to determine the shutter speed, manual mode will require the photographer to specify shutter speed.


4. A photo with a very shallow depth of field.


Use your camera's controls to choose your aperture. Higher aperture values--a lower f-stop number--provide a shallow depth of field with clear areas of sharp and blurry contrast. Lower aperture values--a higher f-stop number--capture a wider depth of field, with a larger area of focus.


Traditional Manual 35mm SLR Cameras and older lenses


5. A traditional manual 35mm SLR camera.


Attach the wide-angle zoom lens to your camera, ensuring it is firmly in place.


6. A photographer using a tripod to hold a camera in position.


Frame your shot. A tripod will help if you are aiming to capture a very large depth of field with a slower shutter speed.


7. A 50mm prime lens with aperture ring.


Twist the thin aperture ring on the lens to choose an aperture appropriate for the shot. Higher aperture values--a lower f-stop number--provide a shallow depth of field with clear areas of sharp and blurry contrast. Lower aperture values--a higher f-stop number--capture a wider depth of field, with a larger area of focus.


8. A photographer, calibrating his next shot.


Set the shutter speed, paying close attention to your camera's light meter to ensure perfect exposure.
