The D7100 doesn't allow the lens aperture to be adjusted during video capture.

And remember: always make your exposure compensations by opening the lens aperture.

The amount of light which reaches the film depends on the area of the lens aperture.

The darkening can be gradual or abrupt, depending on the lens aperture.

This is an easy question for anyone who knows that lens apertures and shutter speeds are reciprocal.

When using flash, you can often choose your lens aperture through the flash unit.

The lens is modified such that each colour channel has a different lens aperture.

The major lens limitation that affects focusing is the lens aperture.

Since the shot was continuous, it was not possible to adjust the lens aperture as the camera left the room and went into the square.

It reeked of oil and fit quite loosely, but she was able to see out of the lens apertures.

The important measure related to DOF is the lens aperture.

(The lens aperture closes down, shutter speeds need to get slower to give the same exposure).

If you want a faster shutter speed to freeze action, you need to use a bigger lens aperture.

The required exposure time depended on the lighting conditions, the sensitivity of the photographic plate, and the camera lens aperture used.

Shutters jam, computer circuits go haywire, lens apertures stick, flashes lose their fire power.

The lens aperture will probably be working fully open, and this may over-expose the lights which will then tend to flare.

And since the viewfinder window is independent of the lens aperture, there's no dimness when shifting focal lengths.

Such a blur spot has the same shape as the lens aperture, but for simplicity, is usually treated as if it were circular.

The lens aperture Prokudin-Gorsky chose to use greatly impacted the exposure time required.

If it's a camera with manual-exposure capability, you can adjust either the shutter speed or the lens aperture - the choice is yours.

The limited depth of field he had gotten by his choice of lens aperture had made the background a soft blur.

The photographer would adjust the shutter speed and/or the lens aperture f-stop until the needles aligned.

Conversely, 'Portrait' AE sets a larger than normal lens aperture.

A smaller sensor produces a deeper depth-of-field, for the same lens aperture, reducing the risk of out-of-focus photos.

In manual mode, the photographer adjusts the lens aperture and/or shutter speed to achieve the desired exposure.
