Why do you need a wide zoom lens?
Any lens which is wider than about 28mm all the way upto 10mm is called a wide angle. However, some lens manufacturers will add some zoom capability to their lens, e.g., 10mm …to 20mm from Sigma, or 12mm-24mm from Nikon or some go even more extreme like 18mm-200mm from some manufacturers...
There is no single answer to this question unless you say more about what you mean by "best"; do you mean the best possible quality, the lightest, the biggest range, widest or… longest or best value?. Having said all that(!), I'd suggest the single most useful lens is the 18-200mm - it covers most common application and has a large zoom range.
It does depend on what kind of photography you want to do; if you want to do sports photography then you need a quite different lens from a landscape or portrait photographer.… Probably the most generally useful lens is the 18-200mm VR.
A zoom lens is a lens of a camera which contains a mechanicalassembly of inner lenses, which allow the focal length of thecamera to be rapidly altered.

A telephoto lens is a camera lens that is typically used for takingphotographs of subjects that are a distance away such as alandscape. They are also used for subjects that th…e photographercan not get close to such as wildlife, and sporting events. A zoomlens allows the photographer to get very close to the subjectmatter and then zoom in.
It depends on the range of the zoom, the size of the film format, and to some degree, the opinion of the photographer. For 35mm cameras, 50mm is considered "normal", and any l…ens that goes from about 50% shorter AND longer than that can be consdered a zoom that works as both wide and telephoto. An example of this school of thought is a 28mm - 80mm lens. However, for some people, that is not extreme enough to qualify. . There are some "superzooms" that range from wide-angle to telephoto in the same lens - the 18-200mm range is available from Nikon and Sigma.
dependant on your application. I have shot with a variety of Nikon zooms and find that for sports and low light the AS-F 70-200mm 2.8 VR is about the best there is. However if… the price on that is a bit daunting, the 70-300mm VR or 80-40mm VR might be up your alley. Although the 2 latter don't have the amazing F2.8, they do have an extended focal length compared to the 70-200. The 80-200 is about 3X the price as the 70-300 and is the most slow autofocusing lens ive ever used. So unless you need that extra 100mm, for the price go with the 70-300. If the price isn't a concern... buy the 70-200 VR and a teleconverter
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.
It depends on the camera. If it has detachable lenses, there should be a variety of zoom lenses available. Vivitar and Sigma are good manufacturers, and of course your camera …manufacturer's offerings are the best choices of all.
digital cameras --------------------------------------- Zooms have been around a Lot longer than digital cameras, but it wasn't until the mid '70's that computers were used… to help design them, making them more affordable and efficient (smaller)
The Canon EF 70-300mm DO IS USM Lens is (arguably) the best Canon EF lens available. It has a focal length of 70-300mm which is excellent for sports and wildlife photography. …It features Diffractive Optics (DO) which handle chromatic abrasion very well, Image Stabilisation which compensates for camera shake and a ring Ultrasonic Motor which allows for quick, quiet and accurate auto focusing. The Recommended Retail Price for this lens is $1,149.
A "zoom" lens just means that the lens can change its length (e.g. 18-55, or 80-200mm). A telephoto lens is one that make objects look significantly "closer" than they really …are (usually defined as anything above 100mm, but this can vary based on the camera model). So confusingly enough, zoom is actually a feature of a lens, and not a type of lens itself. If you are wanting a lens that make far away things look closer then you want a telephoto lens.
ok, so if u mean its stuck half way, like when u turn it on and its getting into focus and stuff, then this is what i did. this seriously JUST happened to me and i was freakin…g out then i figured it out and decided to help someone else out with the same problem . here is what u do... turn the camera on, and it should say something like "Zoom error". take the farthest part of the lens that is out (srry dont really know how to explain it) and kind of pull it out. turn the camera off and it should close properly. With my camera, after i turned it on again, it went back to the same thing. So I grabbed it as soon as it came out. I just basically kept repeating things and trying different things while i turned the camera off and on (i mean with the actual lens, not the camera settings or something) amazing, i figured this out on my own yay me:D lol. hope i had the right idea on wat u meant! if not.. srry bout that! hope i helped!! p.s. now my camera just sounds like its going over a little bump when i turn it on, but it works fine
Both varifocal and zoom lenses are built with movable elements that permit changing the effective focal length. A lens might be specified as 3.5-8mm or 6.5-52 mm, meaning the …focal length can be adjusted within these ranges. The key difference between a varifocal and a zoom lens can be explained by thinking about a lens that has been focused on an object at any focal length. A varifocal will need to be refocused whenever the focal length is adjusted; the zoom will stay in focus when the focal length is adjusted (i.e. when "zooming in" or "zooming out"). While this is an advantage in some applications, if a camera is going to be set-up once at an installation and then stay at the same focal length, the varifocal is a smaller lens that will do the job at a much lower cost than the zoom. Zoom Ratio Another method for describing the range of focal lengths in a varifocal or zoom lens is the zoom ratio. This is ratio of the shortest focal length and longest focal length of the lens. So a lens could be specified as follows: . 6.5-52mm Zoom or 6.5mm 8x Zoom . 13-130mm Zoom or 13mm 10x Zoom The method used to describe a lens is less important than is an understanding of the operating range of a specific lens (for example 3.5 - 8mm), and how the image is affected throughout this range.
