If you are still using a point and shoot film or digital camera, your choice of lens speed is small to the camera. Any way for those of you who decided that it is time to move on and upgrade to an interchangeable lens camera, whether it happens to be film, or digital, you are no doubt have been seeing at the many lens options available. Large majority of citizen switch from a point and shoot to a particular Lens Reflex camera. While overwhelming percentage of citizen move to a Digital Slr, Film Slrs are still popular, and function essentially the same. So, for the purpose of this article, the two types will be treated as one. Lenses are ready in so many dissimilar combinations, and varieties, that discussing them all is far beyond the scope of this article. However, they all have one thing in common. They are all broken down into two groups: slow, and fast. If you are still struggling with choosing your first lens, or just trying to make the right decision, while faced with many choices, this report should help.
[b]Lens[/b]First of all, the speed of the lens is carefully by the size of the opening, known as the aperture. The larger the opening the faster the lens is carefully to be. Typically, lenses marked with F4, F3.5, F2.8, and smaller are carefully fast, while lenses marked with a bigger estimate are slower. I know this may sound odd, but the smaller the estimate the faster the lens. If you are new to shooting with an Slr camera, you are most likely seeing at “zoom” lenses. Most zooms today have a changeable aperture. This plainly means that at the shortest end, the lens is faster than at the long end. For example, a typical lens a 28-80mm. This lens zooms from 28mm to 80mm, and it is a very good starter lens. This type of a lens will typically have a F3.5 gap ,break at 28mm (short end), while at 80mm (long end) it will be F4.5, or F5.6, which is considerably slower than the short end. Typically, the faster the lens, the more it will cost, and the heavier it will be. Most casual shooters look for very versatile lenses, and faster lenses precisely offer more flexibility in inescapable situations.
Now that we briefly discussed the belief of speed, lets shape out whether you precisely need a fast lens. The first thing that you have to think about is your shooting habits. Everybody is different, and very much unique. Some shoot landscapes, some only people, others night scenes, some shoot under water, and so forth. Typical casual shooter will likely shoot during daytime, and will likely be shooting portraits, landscapes, city scenes (during a vacation perhaps), and other fairly undemanding environments. If you shoot a lot of photos in dim light, like night clubs, restaurants, museums, outdoors after dark, and other dim light situations, a faster lens is right on a boon. However, you should always keep in mind that most zoom lenses, while faster at the short end, will be slower at the long end. This is very important, because if are going to be shooting at the longer end of the lens, when shopping for a lens, keep this in mind, and you will save yourself some money. Let me explain. Take two lenses, one is a 28-80mm f2.8(short end) / f5.6(long end), and an additional one lens, 28-80mm f3.5 / f 5.6. These two have an identical range, Any way the first is faster at the short end. This larger gap ,break does not come free. You may end up paying 2 times as much as the second lens. If you are going to be mostly zooming to the long end of the range, compare and price your lens at that end.
If you are going to be shooting mostly portraits and other static landscape and plan to use flash, or a tripod most of the time, you will not need a very fast lens, because the added speed will likely be of small benefit to you. As such, you will do just fine with a F4.0 or slower. Performance shooters often benefit from faster lenses, and if you are planning to capture sports, animals, and other spicy subjects, a faster lens may help at times. The particular biggest benefit of a faster lens is the freedom it gives you, when the light is limited. If you are an Performance shooter, and capture a lot of Performance in dim light, the extra speed will be very helpful, and allow you more hand-held shooting. always rate how much you are going to be shooting in dissimilar environments. Performance and low light shooters will most benefit from lenses with apertures of F4.0, and larger. If you think low light, and Performance will be very infrequent, and you are comparing two similar lenses, choose the funds one, which will likely be just a bit slower. Often, a price of a zoom lens with just a slightly smaller gap ,break at the long end will be hundreds or dollars less than a similarly sized zoom with a slightly larger aperture.
Most modern Digital Slrs can precisely offset the need for a fast lens straight through higher Iso settings, something that Film cameras do by using a faster film. With Film cameras, you would need to switch a roll of film to turn the Iso speed. If you use a Digital Slr, switching an Iso is easy, and could be done at any time. This is a huge benefit, and reduces a need for the faster lenses. Unless you are planning to make money with your camera gear, fastest lenses will not be cost effective.
Consider borrowing, or renting a fast lens, in the range which will meet your shooting needs, and test it in the dissimilar environments in which you will be shooting. If you are not pushing the limits of the lens, chances are, you will be Ok with a slower, more funds cordial alternative. Make sure that you know your budget, and how actively you will be involved in photography. If you plan to trade-up your equipment in a few years, keep in mind that technology only gets better, and manufacture a big investment will make more sense if you are going to get a lot of use out of it.
