No, the aperture controls adjust the size of the opening that light enters the camera through (see image above, left maximum aperture setting, right minimum aperture setting).

Does the numerical aperture of an objective depend on the focal length of the objective?
Yes.
What is the meaning of f3.5-5.6?
On for instance a 35-70mm camera lens the maxmimum aperture at 35mm is f3.5 and the maximum aperture at 70mm is f5.6. (f3.5-5.6) Maximum Aperture of a Variable Focal Length Camera Lens.
The depth of field in a photograph is controlled by the?
Depth of field on a camera is controlled by the aperture. The aperture is basically the size of the opening in the lens. A large aperture (or opening) creates a shallower depth of field and a small aperture creates a greater depth of field. Aperture, along with shutter speed, determine how much light goes into the camera. The size of the aperture is indicated by the f/stop number. The numbers usually range from about f/1 to around f/64. The smaller the number is, the larger the aperture is and the shallower the depth of field, meaning less space is in focus.Additional AnswerDepth of field is also affected by the focal length of your camera's lens. For any given aperture, longer focal length lenses (telephoto lenses) have a much narrower depth of field than a standard lens, and shorter focal length lenses (wide-angle lenses) have a much wider depth of field than a standard lens.

If a 6 o'clock the clock strikes 6times The difference between the first and the last strike is 30 secs Find the time taken when it strikes 12?
6 strikes mean 5 intervals between. So the length of each interval is 30/5=6 12 strikes mean 11 intervals between. The length if each interval is 6 So the difference between the first and the last strike is the length of 11 intervals 6*11=66
What is the meaning of 18-135mm f3.5-5.6g ed-if af-s dx?
This is a Nikon lens that was originally released around 2005. AF-S stands for Auto Focus-Silent Wave Motor. This means that the lens has an autofocus motor built into it, so the cameras used with it do not have to have AF motors built into them. "DX" refers to the size of the camera sensor; the sensor has a 1.5x crop, which affects the focal length and the aperture. "18-135mm" refers to the range of focal lengths of the lens. "f/3.5-5.6" refers to the aperture of the lens; as the lens is zoomed in to longer focal lengths, the aperture gradually increases from f/3.5 to f/5.6. "ED" refers to the Extra-Low Dispersion elements, which reduce the chromatic aberration of the lens. IF stands for Internal Focus, which means the lens length does not change when focusing. The front element of this lens does not rotate when focusing either, so the orientation of front mounted accessories such as polarizing filters does not change during focusing. In photography, the "focal length" of a lens is usually stated in millimeters (mm). The higher the number, the greater the magnification. A "normal" focal length for a 35mm film camera is around 50mm. A focal length of 18mm is considered "wide angle" and 135mm is sometimes referred to as a "portrait" lens. Lenses with higher numbers (200-1000) may be called "tele-photo". The listing for a lens as 18-135mm means it is a "zoom" lens. This means the focal length can be changed by the photographer usually by turning a ring on the body of the lens. As to "f3.5-5.6", in this listing, it is the range of the maximum size of the aperture. The aperture is the opening in the camera that allows light in to take the picture. The f number -- called the "f-stop" is calculated by dividing the diameter of the aperture opening by the focal length of the lens and expressing the answer as a properly reduced fraction (with the top number a 1). The f-stop is the bottom of the fraction. For example: a camera with a 100mm lens that has a maximum aperture of 50mm, or an "f-stop" of 2 (50/100=1/2). On a zoom lens, since the focal length changes, but the aperture does not, the f-stop will change with the focal length. So, the first number 3.5 means at the lower focal length (18mm) the maximum aperture opening is 1/3.5th of the focal length, or about 5mm. The other number 5.6 means at the higher focal length (135mm) the maximum aperture opening is 1/5.6th of the focal length, or about 24mm.
