We're going to assume that you mean "focal lengths".
Camera lenses don't typically have very long focal lengths. The lenses with very
long focal lengths are the ones you see that look like a big tapered piece of pipe
sticking out on the front of the camera. Those are the extreme 'telephoto' lenses ...
designed to blow up magnify (sorry) small objects in the distance. It's nearly impossible
to hand-hold the camera steady enough with such a lens, and you almost always see
them used with the camera mounted on a tripod for stability.
Here's a somewhat-related fascinating and useful factoid:
One focal length on the film = one radian (57.3 degrees) in the scene

Does camera lenses have long or short focal points?
The short focal length of a camera lens is so that the image the lens forms is small and can be focused on a piece of light-sensitive film.
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
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.
What does 55mm camera mean?
The question likely pertains to 55mm as a lens focal length, and does not relate to any type of camera. Another use for numbers like 55mm in connection with a lens is to designate the thread size of the filters and lens caps that lenses require. For the interchangeable lenses used on 35mm SLR cameras, those sizes commonly run from 49mm to 72mm. Cameras are designated by film size or by type. Some common camera designations are 35mm; SLR; rangefinder; digital; point-and-shoot; medium format; view camera; press camera (various types); TLR twin lens reflex) -- there are others. If there is a "55mm"camera, I haven't encountered it.
Why should a camera be move from the object in order to obtain a sharp image?
I believe you are talking about minimum focusing distance. If your subjet is too close to the camera, then the lens may not be able to completel focus on it. Diferent lenses have different focal lenghts. Some Wide angle lens can work at 20 to 25 inches, while some larger zoom lenses need more than 3 feet of minimum focusing distance... If you are using a compact camera, then you could try using the macro mode to work really close to the subject you are trying to shoot.

Which focal lenses make the best Samsung digital camera?
18-55mm focal lenses are very good lenses for the Samsung digital camera. Other good lenses for the Samsung digital camera are the 28-90mm and 35mm focal lenses.

Why camera shake more apparent when using longer focal length lenses?
Camera shake is more apparent when using longer focal length lenses because they magnify any movement made by the camera. This magnification effect makes even slight movements more noticeable in the final image. Additionally, longer focal length lenses have narrower fields of view, which can amplify the impact of camera shake on the composition.
Does camera lenses have long or short focal points?
The short focal length of a camera lens is so that the image the lens forms is small and can be focused on a piece of light-sensitive film.
What are the best lenses for a Nikon D3200 camera?
The best lenses for a Nikon D3200 camera are typically prime lenses with a focal length of 35mm or 50mm for general photography, and a wide-angle lens for landscapes or a telephoto lens for wildlife and sports photography. It is also recommended to consider lenses with a wide aperture for better low-light performance and depth of field control.
What is zoom lens?
A zoom lens is a lens of a camera which contains a mechanical assembly of inner lenses, which allow the focal length of the camera to be rapidly altered.
What are the best camera lenses for iPhone 6 to enhance photography capabilities?
Some of the best camera lenses for iPhone 6 to enhance photography capabilities are Moment lenses, Olloclip lenses, and Sandmarc lenses. These lenses can improve the quality of your photos by providing different focal lengths and effects, such as wide-angle, macro, and telephoto.
What are the main differences between zoom and telephoto lenses in terms of their focal length and magnification capabilities?
Zoom lenses have variable focal lengths, allowing you to adjust the magnification level by zooming in or out. Telephoto lenses have a fixed focal length, typically longer than standard lenses, providing higher magnification for distant subjects.
How does the 30mm comparison of different camera lenses impact their performance and image quality?
The 30mm focal length of camera lenses affects the field of view and perspective of the images they capture. Different lenses with a 30mm focal length may have varying optical qualities, such as sharpness, distortion, and color rendition, which can impact the overall performance and image quality of the photos taken with them.
What are the different types of lenses?
Some common types of camera lenses include prime lenses, which have a fixed focal length; zoom lenses, which have variable focal lengths; wide-angle lenses, which capture a broader field of view; telephoto lenses, which magnify distant subjects; and macro lenses, which allow for close-up photography.
What are the differences between the Reikan Focal and LensAlign systems for calibrating camera lenses?
The Reikan Focal system uses software to automatically calibrate camera lenses, while the LensAlign system requires manual adjustment of the lens. The Reikan Focal system is more user-friendly and convenient, while the LensAlign system may provide more precise results for advanced users.
