Buying a lens is neither an easy nor a superficial matter. It all depends on your needs and preferences. The main difference between a prime lens and a zoom lens is of focal length.
While prime lenses have a fixed focal length, zoom lenses, on the other hand, have a wider and variable focal length. Prime lenses tend to be smaller, lighter and offer better low light performance than zoom lenses. Zoom lenses are generally heavier but thanks to their wider focal range, they are far more versatile. A prime lens is one where you cannot change the focal length i. Unlike a zoom, getting your subject closer or further away is only possible by physically moving.
This has some other implications aside from the magnification of the subject. When the distance between the camera and subject changes, you have to consider more factors. One of these is the compression effect. This refers to the apparent separation between the subject and the background. The depth of field will also be different, because the closer you are to the subject, the narrower it will be. You should also consider the lens distortion — for example, a wide-angle lens tends to distort the subject to some degree.
So, moving back and forward with a prime lens is not the same as using a zoom lens. As you might have guessed already, zoom lenses have movable focal length. This means that by moving the optical elements inside the lens, you can change the angle of view. Sometimes this means that you can have three types of lenses in one: a wide-angle lens, a normal lens, and a telephoto lens. For example, with a mm zoom lens would cover the whole range. In other cases, it stays within the same lens type while still offering a range variation.
For example, a mm is a wide-angle zoom lens. On the other side of the spectrum, you can get a telephoto zoom lens ; one of the most common is the mm. With zoom lenses, you can get your subject to appear closer or further away with the turn of a ring, and without changing the physical distance. Left: 90mm prime Right: mm zoom. Credit: Greg Cromie. Some people argue that prime lenses provide a higher image quality.Marlin model 1897 serial numbers
However, there have been great improvements in zooms from most manufacturers. I believe some zoom lenses can deliver the same level of quality. Not all of them though — which brings me to the first advantage of prime lenses. A good prime lens will be cheaper than a good zoom lens. It will give you better quality and sharper images.
Prime lenses are much lighter than zooms because they have fewer optical components inside. This might sound like a shallow consideration in choosing the right gear, but there are two arguments I could say in defence of it. First, the quality will not suffer, and often it will be higher than with a zoom.
Second, a heavy lens is not a minor issue. As a result, you could end up missing some great shots. You need only consider the growth of the mirrorless market to see that the issue of size and weight is real. Many photographers are now choosing mirrorless cameras over DSLRs because of their lighter weight.

A Guide to Using Macro Filters for Close-Up Photography
Indoors and outdoors? For sports or only for reading or desk work? Driving day and night? Your lifestyle and habits should inform your coating decisions. Put price in perspective. Some types of coating, like those that are anti-reflective sometimes called glare-reducingcome in a range of prices.
Ask for an itemized description. In many cases, eyeglass lenses come bundled with certain coatings, commonly those that reduce reflections or bolster scratch resistance. Avoid the hard sell. Scan the warranty. Many glasses will be backed up by some kind of warranty, but it might not cover coatings. Or warranties may vary in terms of which ones are covered and for how long. What can you expect? No matter what your warranty says, if a coating starts to degrade within a year, Vitale recommends taking the glasses back to see if you can get the problem fixed or the glasses replaced.
Brodie, M. Who might consider: Most people, but AR coating may be especially useful for those who often drive at night it can reduce reflections from headlights at night and read on computers.Most digital cameras are equipped with a zoom lens as standard. However, some perform with a digital zoom. But how does the optical zoom differ to the digital zoom and what are the pros and cons of these two zoom systems?
Zoom lens ranges are measured by the number of times the image can be magnified. For instance, a 35mm — 70mm zoom lens has a magnification of X2; a 35mm — mm lens has a magnification of X3. The higher the magnification range, the more flexibility the lens offers. All such magnifications are achieved by the optical zoom as the magnification is achieved by a series of specially-curved lenses. The resolution of the image is not affected, as the image is simply viewed by the same principle as peeking through a telescope.
But in most digital cameras, the digital zoom cuts in at a certain magnification. The digital zoom works merely by cropping the image viewed through the viewfinder to give the impression it has been magnified optically. Digital cameras with a limited zoom capacity with a magnification range of, say X2 or those with a fixed lens may be fitted with a digital zoom function in order to zoom further by cropping the image and enlarging.
A little bleep might sound, or a marker goes over a point on a bar, displayed on the LCD screen. The image resolution will be degraded from this point on. Once the image has been cropped, the total number of pixels left in the image will be reduced. The result? The image resolution will be reduced drastically and the resultant print will appear grainier. Why use the digital zoom when the image can be cropped in the image software anyway? Personally, I would avoid using the digital zoom altogether.
I would invest in a digital camera with a more powerful optical zoom say X5 or more as can be found in an ultra zoom camera, or a digital SLR which enables the photographer to change the lens.
Once I have reached the maximum optical zoom capacity, I will leave it just there and take the shot, even if the object still appears small on the viewing screen. I can then keep a copy of the initial shot and then crop the copy if it contains something interesting not previously noticed. The digital zoom does not really zoom into a scene in the same way as the optical zoom. It merely crops the image and then enlarges it so that it fits the LCD screen. This will cause the image to lose resolution and appear grainier when it is printed.
If image quality is paramount in photos, I would invest in a digital camera with an ultra zoom lens or a digital SLR.

It only takes a minute to sign up. I'm aware that the constant-aperture F4 gathers more light than, say a F3. I'm also aware that constant-aperture lenses are heavier, bigger and more expensive.
What are the other tradeoffs? Would I get a lens of better quality for the same price if I don't insist on a constant aperture? Do constant-aperture lenses make a practical difference for low-light shooting, in aperture or shutter speed priority mode?
And, taking a step up from F4 constant-aperture zooms, how do F2. Are they generally as sharp as prime lenses? In other words, if I don't need a wider aperture than F2.

Do constant-aperture lenses make a practical difference for low-light shooting, in aperture or sheet speed priority mode? Many times when shooting action in limited light you are using manual exposure mode with the widest aperture and the slowest shutter speed you can without getting camera blur or blur from the motion of your subject s.
By using a constant aperture zoom lens you don't need to change the ISO to compensate for the change in aperture as you zoom. Many cameras allow the use of Auto ISO in manual shooting mode but some don't. ISO, etc. For what I shoot on a regular basis there is a world of difference between a constant aperture zoom and a variable aperture one.
In general constant aperture zooms tend to have better optical quality than variable aperture zooms. It is not so much an inherent quality of a constant aperture design as it is an indicator of what the market demands out of higher priced lenses. Usually, but certainly not always, the tradeoff isn't better optical quality in exchange for a variable aperture design.
Rather it is variable aperture in exchange for a cheaper price. That all depends on the particular lens.Incredible Hollywood Lenses for LESS than $3000 (Review of DZO FILM Pictor Cine Zooms)
A few other zooms are very close or equal to their prime counterparts at the same aperture settings. But there are other zooms whose image quality falls far short of their prime or narrower aperture counterparts. It's also quite a bit more expensive than the others. But the less measurable characteristics of any two lens designs will vary from one to the next.
How the out of focus areas are rendered, for example. Something the other answers don't touch on: fast f2. Special elements and coatings on elements are used to make these lenses better and more expensive than variable-aperture lenses.
I'm really only familiar with the Nikon line-up, where that means more elements with nano crystal coatings "N"more extra-low dispersion elements "ED"and more aspherical elements, as well as better weatherproofing. The short answer is that it is most advantageous for Video, because when you zoom in everything doesn't get darker.
For single frame Photos you can adjust ISO and Shutter speed the automatic Setting will do it for you on a shot by shot basis and get all Photos similar; in a Video such variance would not be tolerated.Melodigrand piano 64 key
The design and manufacturing of varying aperture Lenses is less expensive than constant aperture; but that doesn't mean you couldn't use a variable aperture Lens at a constant aperture, simply set your Aperature to the higher number or greater and the higher value is your minimum and constant.
The lower the F number, the ability to zoom and constant aperture for Zoom Lenses are all factors that can increase the cost. Some constant aperture Zooms are less expensive than some Primes, and vice versa; quality being the main factor for expense in either of those cases. If you will almost always take Videos either wide field of view not zoomed in or in bright sunlight then you can buy a non constant aperture Zoom and save a bit of money.
The advantage of a constant aperture zoom is that you can zoom in and out as much as you like without changing exposure - it's just one less thing to worry about, that's it. And as for you question about how constant aperture zoom compare to primes, it's like everything else in lenses, the latest generation top of the line lenses are really amazing but also really expensiveolder or cheaper lenses vary in quality.By Ian Robert Knight. Zoom lenses seem to have it all.
But is that really true? Can one lens do it all? In this post, we are going to discuss the pros and cons of Zoom Lenses.Ensueno baby fabric softener
Because of this, Zoom lenses have a high level of convenience about them. But what is the cost for that convenience? What do we gain and lose when we use a Zoom Lens?
The convenience of never having to switch lenses in the middle of a shoot is certainly attractive. If you are shooting a subject that is moving around, you can sit in one spot and Zoom your lens to keep the subject at the same relative size. Having a Telephoto Zoom Lens will give you the flexibility of enlarging or reducing the size of the subject simply by zooming the lens.
With Wide Zoom Lenses, the same advantage is given, except in a less obvious way. With Wide Zooms, you can adjust the focal length of the lens so that you can see more of the scene around you.One step equation games
With a Wide Zoom, you can zoom out further and further until you get the field of view you want. Think of Zoom Lenses as a large collection of Prime Lenses in one small package. Carrying four lenses can really add to the weight of the bag you have over your shoulder.
But one Zoom Lens is just one lens, right? If the maximum aperture is slow, then that means you will get longer or slower shutter speeds. Or you are forced to use higher ISOs in order to get the photo. But Fast Zoom Lenses cost and weigh a lot more.
In order to make a Zoom Lens that has a wide range of focal lengths, manufacturers have to make some compromises. But what they also did was they moved around.

Although this seems obvious, what may not be apparent is that the photographers gained an advantage by moving around. They would have different light, different postures, different shadows, etc. Zoom Lenses tend to make photographers lazy. If the subject moves away, we zoom some more.
Interestingly, studies have shown that most people that use Zoom Lenses tend to shoot most of their photos at the extreme ends of the lenses. That is, if you use a mm, chances are pretty good that most of your photos are shot at 24mm or 70mm. Almost none of the photos would be shot at 42mm or 61mm or anything like that.
With all that said, there are good reasons to use a Zoom Lens, if it fits your needs. Often the sheer convenience of having less equipment is worth it alone. Or perhaps your budget only allows for one lens.The best lens for concert photography should have large maximum aperture, fast and intelligent autofocus, long zoom range, built-in image stabilization, and a weather-sealed body. I recommend you buying a pair of zoom lenses 24—70 and 70— mm with a 2.
The images taken with a wide-angle zoom have a striking effect, since you may shoot the whole band or capture the most part of the audience. Optical lens construction is rather complicated and consists of 18 elements in 13 groups, among which we may find aspheric lenses as well as low-dispersion elements. This concert photography lens by Samyang has manual focus but there is also the internal focus information in the viewfinder at least Nikon offers it.
I can claim that it is a pleasure to work with this lens, actually. The focus ring turns very smoothly making the focus extremely sharp. There is no lose play in the aperture ring and it stays solid when you set the aperture. Although it is developed in a plastic body, this lens may compete with expensive L lenses in quality. Moreover, the plastic does not seem low-cost.
You may correct lens distortion in Lightroom or Photoshop, which provide a special profile for Samyang. The images are bright and sharp and little distortion in the corners is not a big deal.
Tamron mm is considered to be the lightest and the tiniest 15x zoom lens across the camera gear market. It is one of the best lenses for concert photography thanks to its portative size, light construction, new Piezo Drive PZD AF system, and VC picture stabilization technology.
It is quite difficult to take sharp images shooting at long focal lengths. Luckily, this concert photography lens comes with an integrated VC technology so you will not get blurry pictures.
Moreover, correct settings will help achieve better results. With such adjustments, the parameters will compensate each other and you may use illumination solely accessible in the hall.
Furthermore, the events on the stage will look realistic in the frame.
Concert photography equipment must be very qualitative. The developers did not compromise on picture quality and equipped it with the improved VC system. This technology minimizes the camera vibration and is useful in low light conditions and for capturing fast-moving objects.
Powerful zoom, ultra-fast autofocus, and high power resolution are the main advantages of this model. Thanks to the constant maximal aperture, you may get qualitative images even in poor lighting without changing the exposure settings on the whole focal distance range. The convenient location of the switch, regulating change from manual to auto focus and focus hold buttons make the shooting a pleasant process, allowing you to control it without any difficulties.
Water and dust resistance is essential for concert photography lenses since you may shoot in severe weather conditions. This is a modern lens, the first that Sigma produced for the Art line of the Global Vision series. It is among the best lenses for concert photography due to the unique concept and lens design of the new development. The 35mm focal length paired with the Sigma technology opens new possibilities to render your artistic vision.
The Hyper Sonic Motor provides noiseless operation, high speed and accurate autofocus. The floating focusing mechanism provides incredible optical performance with the objects situated closer.If your budget or travel requirements limit you to just one lens, a superzoom provides a lot of bang for the buck.
Also, these all-in-one zooms give you the ability to shoot a wide-angle landscape and then zoom in on wildlife in an instant. The focal-length flexibility is the strongest single advantage of an all-in-one zoom. Each focal length creates its own aberrations and distortions, and requires its own solutions. That said, the superzooms usually perform better than the typical mm kit zooms sold with many DSLRs, making them great alternatives or step-up lenses.
PRO: Compact Package Next to focal-length flexibility, the main advantage of the all-in-one zooms is their compactness. That certainly beats carting several lenses around when you want to travel light. With just a camera body and a single lens, you can easily conceal your gear or carry it with you everywhere you go.
This makes the pro zoom much better for shooting in dim light, especially at the longer end of its range. Faster lenses also provide a brighter SLR viewfinder image for composing and visual focus confirmation, and faster lenses help considerably with autofocus. And a wider maximum aperture means you can shoot with less depth of field, which is necessary for selective-focus images of flowers and such at the long end of the focal-length range.
That makes them great deals in terms of cost and versatility. If you were collecting a number of lenses to fill the same 8x or greater superzoom focal range, you easily could spend a couple thousand dollars or more—much more. The superzooms incorporate low-dispersion and aspherical elements to reduce the adverse effects of aberrations and distortions, and do a remarkably good job, considering their cost and focal-length range.
Their price makes a superzoom a very attractive option for many photographers. With a superzoom, one of each filter type covers all of your focal lengths. You just need one polarizer, neutral-density, grad, etc. Besides the cost savings, using one superzoom in place of several prime lenses or shorter-range zooms means less stuff to keep track of like filters, lens caps and cases.
