Do camera lenses typically have very long focal points?
We're going to assume that you mean "focal lengths".Camera lenses don't typically have very long focal lengths. The lenses with verylong focal lengths are the ones you see that look like a big tapered piece of pipesticking 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 impossibleto hand-hold the camera steady enough with such a lens, and you almost always seethem 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 type of camera lens which enlarges distant images?
Camera lenses that enlarge distant images are normally known as long focus lenses or telephoto lenses. A few specialist lenses use mirrors as well as glass and are frequently referred to as mirror lenses.
What are the camera lens' with the side things called?
A camera lens may have a shield called a "lens hood" encircling it to prevent strong light entering from the side. Although such side light would not be focused with the image, it could reflect off the internal surfaces of the lenses to cause a "flare" of light within the image. This problem is more critical in lenses with many elements and lenses of long focal length, so we most often see lens hoods on telephoto lenses.
What uses a long focal length a short focal length lens and has an inverted image?
a camera? Or an eye? Something like that. Weird question
How to Find a Quality Digital SLR Camera Lens?
Artistic photographers may prefer a still camera over digital. With the advancement in digital SLR cameras photographers have more flexibility and options to work with. Let this guide help you find a great digital SLR Lens. ▪ Step 1: Determine the brand of digital SLR camera you own. Lenses are unique to each name brand and are not interchangeable. You must purchase and use lenses that are made for your cameras model. A digital camera lens is not the same as a still camera lens where you might be able to get away with interchanging lenses from other name brands. Digital camera lenses actually connect electronically relaying information back and forth to the camera. ▪ Step 2: Decide on a focal length. There are two main types, prime and zoom. Prime lenses offers a fixed focal length meaning it cannot be change, provide a clearer picture, are lighter in weight and are inexpensive in comparison. Prime lenses are the best to use for pictures taken in low light without the flash. Zoom lenses have a changeable focal length and are the most common type of lenses used with digital cameras because they provide flexibility. Zoom lenses range in price and are heavier than prime lenses. Higher quality zoom lenses will be expensive because of a wider range of focal length and optical clarity at each length. Super zoom lenses are the highest range of focal point but the does not mean this is the best lens to purchase. Once you determine the type and level of photography you will be doing you will most likely want to buy a specialty zoom lens in the focal length range you use the most. ▪ Step 3: Determine a maximum aperture. A wider maximum aperture lens will let in more light allowing you to take high quality clear photographs without the use of flash. This is specifically important in areas of natural lighting, overcast conditions or low lighting. The depth of will determine the depth of field; this is important in photographs where the photographer wants to have a focal point blurring the background. The faster shutter speed prevents motion blur, especially in photographs of lower lighting conditions. ▪ Step 4: Choose a direct or indirect lens manufacturer. Many third party lens manufacturer’s sell similar lenses to direct manufacturer’s for a reduced price. Usually the savings will cost you in quality but some indirect lenses are now offering comparable quality and features to direct lenses. Indirect providers are interchangeable between cameras as long as the lenses mount fits. ▪ Step 5: Choose extra lens features you will need. Digital SLR lens offer extra features; depending on price you can purchase lenses with a non-rotating front element, silent autofocus, crop reduction, full-time manual focus, internal zoom, superior optics and image stabilization. Which extra features you will need to splurge on is a personal and professional decision. Whether a hobbyist or professional photographer, photography is fun and creative. Research available lens brands connectable to your digital camera, decide on a focal length, shutter speed and extra features suitable for your style of photography. Your digital SLR camera lenses will make your photography a rewarding creative experience.
I have a Nikon slr d5000 and was wondering if the extra lenses had to be made by Nikon to fit my camera?
No as long as they have the correct mount.
In photography what is a telephoto lens?
When being used in photography, a telephoto lens is used as a long focus lens. This means that the focal length of the lens is longer than the physical length. This type of lens is often used for photography of animals.
If a telescope has an objective lens of 3 inches what is the focal length?
The size (diameter) of a lens does not determine its focal length. The amount of curvature of the lens does. Citing a diameter for a lens doesn't help us find the focal length. Lenses are ground to specifications that allow short or long focal length. The more curved the lens, the shorter the focal length. You can see this if we specify a given curvature and then start to "flatten" the lens. The focal length will get longer and longer as the lens is flattened. When the lens is flat (has to curvature) the lense has an infinite focal length, just like a piece of flat glass.
What is best for fast moving sports photography a Nikon D40 or a Canon EOS 400D?
Alas, the lens is more important than the body for sports photography and suitable lenses for fast moving sports are fast, long focal length. These lenses are expensive and will dwarf the cost of the body.
