The aperture of a lens system is the opening between the actual lens elements, typically made of glass or plastic, and the camera's digital sensor that translates the light into image data. Aperture openings are referred to in terms of stops or f-stops that equate to the ratio of the lens focal length to the diameter of the opening. A lens system with a focal length of 50mm and an aperture opening that is 25mm in diameter would equate to an f-stop of 2, and would be known as a 50mm f2 lens. Some lenses have variable apertures that can be set to one of multiple f-stop values. Reducing the aperture size decreases the amount of light that makes it to the sensor as well as increases the amount of depth of field that the lens will provide.

Where is the aperture ring on d80 Nikon


If you are using an older lens the aperture ring will be close to the camera body when the lens is on the camera. In order to set the aperture with a D80 and older lens you must set the aperture ring to "22" or the highest number on the aperture ring available. For newer lenses there is no aperture ring. You set the aperture by setting the dial on the top left of the D80 to "A" for Aperture Priority. You then set the aperture by rotating the front dial on the right side of the camera under the shutter release button. On older lenses, after setting the aperture ring to the highest number, you then set the aperture in the same manner.

How do I switch to an aperture higher than f/32 on my nikon d3000?


Yes. Just lock the lens aperture ring at its smallest setting (largest f/number). If you need to change the aperture, change it from the camera body by turning the command dial, the same way as with a lens without an aperture ring.

Zoom and aperture problem


What lens do you have on the camera? Many zoom lenses have a variable maximum aperture. This means that the maximum aperture varies depending on the focal length. If you set the lens to its maximum aperture and then zoom, the aperture may change.

Message: Lock lens aperture ring at minimum aperture (largest f-number) I think I'm doing this but the message won't go away and the camera won't work.


You must lock the aperture ring to f/22, so the camera can engage the aperture adjustment lever on the lens. Then, you can change the aperture with the command wheel.

When you change the aperture with the command wheel the aperture ring on the lens doesn't move when the camera actually adjusts the lens aperture.

Take the lens off and locate the aperture adjustment lever on the lens mount.

Unfortunately, this won't work with older AF lenses. So if you are using an older lens, the only thing you can do is change the camera setting to M (Manual) to adjust the aperture on the lens yourself.

You're apparently using a lens with an aperture ring. Turn it to its smallest aperture (largest f/number). You control the aperture from the camera body, the same way as on a lens without an aperture ring.

If the lens doesn't have an aperture ring, clean the electrical contacts on the back of the lens and in the lens mount.

My 17-35 nikon lens will only operate at 22 aperture on my D-70 camera.


Since the 17-35mm AF-D lens has an aperture ring, it must be locked at its minimum aperture. You control the aperture from the camera, the same way you do so on a lens without an aperture ring.

How do I change the aperture on my N6006? And what do I change it to? I keep getting a fE E error message.


That depends on the exposure mode.

In any of the P modes, turn the aperture ring on the lens to its smallest aperture (largest aperture) and lock it. You control the exposure by turning the command dial on the camera.

In S mode, lock the aperture ring as above. Turning the command dial changes the shutter speed and the aperture changes to match.

In A mode, control the aperture by turning the aperture ring on the lens and the shutter speed with change to match.

In M mode, control the aperture by turning the aperture ring on the lens and control the shutter speed by turning the command dial.

If the lens doesn't have an aperture ring, you can only use the P and S modes.

What does it mean when FEE is in the view finder


FEE means that your lens is not set to the smallest aperture setting. If you are using your camera's auto-focus mode, the lens must be set to the smallest aperture setting which, on your lens, is probably f22 (the smallest aperture is the largest number). Once you set the lens aperture, you should slide the aperture lock to the locked position. The aperture lock is located just right of your largest setting f3.5. This slider should line up with the orange line. To verify that the latch is engaged, try to change the aperture by rotating the aperture ring. In the locked position, the ring will not turn.
