On a digital SLR camera, anything less than about 32 mm (50 mm for a 35 mm film camera). The focal length of a wide angle lens varies depending on the size of the negative or digital sensor. Most camera manuals for smaller cameras will give you an idea for that camera, often in 35 mm equivalents, so use the 50 mm standard for those.

∙ 11y agoA wide angle camera, or a camera set to wide angle, will see more of the landscape, though the scene will appear in the viewer further away. Having a wide angle means the camera can be used in smaller spaces, such as indoors, etc. As the camera lens zooms out, so the landscape appears narrower, closer, and has to be kept steadier to avoid camera shake.

∙ 8y agoPhotographic lenses with extremely wide angle of view are also known as 'fish eye' lenses, and usually have an angle of view of 100 - 180 degrees. They are also commonly used as 'peephole' viewers in entry doors. The actual focal length description rather depends on the associated technology - for short focal length purposes such as a video camera, they may have focal lengths of only a few mm. For standard 35mm equivalent, the focal length will be between 10 and 20 mm.

What lens has a short focal length and produces a small image that includes much of the surroundings?
That would be a "wide-angle" or a "fish-eye" lens.
What is a Wide-angle lens in photography?
Typically a lense of shorter focal length than 35mm. It is called wide-angle because the angle of view is wide, up to 180 degrees for some fisheye lenses.
What is focal length of a door peephole's lens and is it concave or convex?
The lens in a door peephole is a convex lens with a very short focal length, giving it a wide field of view. If it were on a camera, it would be called a "Fisheye lens".
What does the 18-200 camera lens digits stand for?
18 mm is the wide angle focal length and 200 mm is the telephoto limit of the zoom. for more info searching on focal length and field of view will give you lots of info.
What it means 18mm - 200 mm in photo lens?
This describes the focal length range of the lens. It means that the lens can be set between 18mm (a wide angle which takes in a larger field of view) and 200mm (a telephoto, which creates a narrower field of view). ******* Note: the above is certainly true for 35mm format, but focal length is relative to the format. For 4x5 cameras, the equivalent "normal" focal length is around 200mm.
What is the meaning of focal length in camera?
The focal length of a camera's lens refers to the the magnification or telephoto power of the lens and is expressed in the millimeters of the lens, like 100mm, 300mm, etc. www.goldprints.com
What is the X in digital camera zooms?
The lens of a digital camera has a certain focal length, expressed in mm. For example, a 50mm lens has a field of view that approximates what we see with our eyes looking straight ahead. A 25mm wide-angle lens has a field of view that approximates what we see with our eyes when we turn our head from side to side. The shorter the focal length of a lens, the wider the field of view. The longer the focal length of a lens, e.g. 300mm, the narrower the field of view. Of course, a narrow field of view is equivalent to zooming in to a far object, like when we look into binoculars. A lens can either have a fixed focal length, e.g. 25mm, 50mm, 300mm, etc. or can have a range of focal lengths, e.g. 25mm - 100mm, 50mm - 300mm, etc. A lens that has a range of focal lengths is called a zoom lens. The zoom factor of the lens is calculated by dividing the maximum focal length by the minimum focal length. That zoom factor is the "X" you are referring to. For example: 1. A 25mm - 100mm lens is a 100/25 = 4x zoom lens. 2. A 50mm - 300mm lens is a 300/50 = 6x zoom lens. 3. A 50mm - 200mm lens is also a 200/50 = 4x zoom lens. 4. A 100mm - 400mm lens is also a 400/100 = 4x zoom lens. So knowing the zoom factor of a lens alone does not tell you what its minimum and maximum focal lengths are. Both examples 1, 3 and 4 above are 4x zoom lenses, but example 1 has a minimum focal length that is a wide-angle and allows us to take wide landscape shots or include all our classmates in one shot. Example 4 has a maximum focal length that is a long telephoto and allows us to bring far object near.
What is 28mm wide angle lens mean?
A 28mm wide angle lens is basically a wide angle lens for a 28mm camera. The book definition for wide angle lens it... "a camera lens having a wider than normal angle of view (and usually a short focal length); produces an image that is foreshortened in the centre". In may words, "A lens that you put on your camera that makes the frame (frame- what you see) wider. Ex. If your zoomed out all the way and your pointing your 28mm camera at a chair. You can see the whole chair and just the chair. If you put on your wide angle lens, you can see more. You could fit two of those chairs in your frame now. Basically, it makes your frame wider.
What is the name of a wide angle lens that starts with fish?
The wide angle lens is called a fisheye lens.
What happens when you put a wide angle lens on a camera with a fisheye lens at the same time?
A fisheye lens IS a wide angle lens
What is a sentence with the word focal?
Wide-angle lenses have a short focal length. The focal character of my short story is a ten-year-old boy.
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.
