 Okay, so you finally decided to get that digital video camera you’ve been saving for. You have enough money to buy a kick-butt video camera. But have you considered the most vital part for the camera? The part that comes into play with every video shot. The digital video camera zoom lens. Without a proper digital video camera zoom lens, your prized video camera isn’t all it could be. You would be much better off if you spend equal amounts on the camera and the digital video camera zoom lens. The lens is that important. Your choice of lenses can distinguish between a good camera and an outstanding camera.
Spend More On The Lens
The digital video camera zoom lens determines how well your videos turn out. It, more than anything else on or in the camera affects the end products. Think about it, every shot you take goes through that lens. Really the camera is just a case for the mechanisms inside. You could make a case for reversing the spending, more on the lens and less on the actual camera. Most digital video cameras don’t come with the ability to change lenses. This fact makes it more important to purchase the best digital video camera zoom lens possible. Another piece of advice regarding the lens is too not purchase the plastic lenses. The clarity is much better from glass digital video camera zoom lens.
If you do plan on purchasing a video camera where you can change the digital video camera zoom lens then compare the options of each lens to find the one that you want. Experts recommend that you purchase brand names such as Canon, Pentax or Nikon. Be sure to check if the lens will work for your camera. Digital video camera zoom lenses are not created equal and a lens from Nikon may or may not work with a digital video camera made by Canon.
If you are a professional photographer, then you should check out Leica, Carl Zeiss and Leupold. These are specialty lens manufacturers. The quality of the videos will show if you use one of their digital video camera zoom lens. If you are just a beginner then these lenses may not be the best place to start, because of the cost. But if you want extraordinary quality, these digital video camera zoom lenses are the way to go.
Options for digital video camera zoom lenses include normal, wide angle and telephoto. The focal length of the lens has a lot to do with the type of digital video camera zoom lens choice. The quality of the lens is also determined by lens speed, a significant factor in your shoot quality. You should think about focusing distance as well as advanced features such as vibration reduction, USM or ultrasonic motor and filter thread which should be present in any good digital video camera zoom lens.
Before you make that digital video camera zoom lens purchase you should research each feature that you want and choose the lens that fulfils those wishes the best. As a rule of thumb, the more expensive lenses are usually the better choice since more of the elements in the lens with be glass, although this does increase the camera weight. In the end if you do the research and take into consideration your shooting needs and budget, you will make the right choice

 Single lens reflex cameras are advanced, high-end cameras favored by professional photographers and amateur enthusiasts. Such photographers gravitate toward SLR cameras because they are faster, take more precise photographs, and are more adaptable.
Have you ever used a film camera and noticed that photo you took is slightly off-center from the image you framed through the viewfinder, especially on close-up shots? This happens because one cannot look through the actual lens of the camera-the shutter and film (or in the case of digital cameras, the image sensor) are in the way. Thus, the viewfinder is off to the side of the actual camera lens, resulting in two slightly different angles of view.
SLR cameras fix this problem by using mirrors and prisms to let the photographer see through the camera lens. It achieves this by lowering a mirror into the lens box. The mirror reflects the image coming through the lens upward into a prism, which in turn bounces the image into the viewfinder. This way, the photographer is able to see exactly what the camera lens is seeing, with the exception of the brief instant when the photograph is being taken.
At this point, the mirror flips up out of the way of the lens box. The shutter opens, exposing the film or image sensor to the light coming through the lens. The picture is captured, the shutter closes, the mirror drops back down, and the photographer can once again see through the viewfinder.
The introduction of digital “point and shoot” cameras changed the game slightly. They also allow the photographer to see exactly what the lens is seeing. They have limitations, however, that some professional photographers feel make them unusable. The main drawback of commercial digital cameras is a considerable lag time between when the photographer pushes the button and when the camera actually captures the image. During these seconds, the camera may be jostled, the angle change, the lens shift out of focus, or the subject being photographed may move. Although perfectly fine for still pictures, photographers who need to capture an image instantly, such as sports, action, or wildlife photographers, the lag time is unacceptable.
A new generation of Digital SLR cameras (DSLR) combine the best of both technologies. They use the SLR mirror system to allow the photographer to see exactly what the lens sees. Simply by replacing the film behind the shutter with a digital light image sensor instead, a DSLR camera is still able to capture images instantly. In this way, a DSLR camera combines the accuracy and speed of an SLR camera with the convenience of digital cameras.
As DSLR cameras are usually high-end machines intended for a professional market, they tend to be more expensive, but also incorporate other advanced features. An average DSLR camera usually includes auto focus options, live preview, electronic flash controls, the ability to swap specialized lenses, and electronic adjustment of the captured digital image, such as optimizing the contrast and color, red-eye correction, and monochrome options, among many others. DSLR cameras also generally have a larger digital image sensor, providing better quality images with a higher pixel resolution, lower noise, and a superior color range. While the price of DSLR cameras make them a financial investment, professional photographers and amateur enthusiasts will consider it well worth it.
