Choosing The Right Lens When shopping for a Digital SLR Camera people often overlook or skimp on the camera's lenses. Camera Lenses serve as the digital SLR cameras "eye," the lens determines what and how your camera will see your subject and how well that view is transmitted to the camera's sensor chip for recording. Slowly, but surely, the worth of the fixed focal length lens (or prime lens) to the non-professional photographer is being eroded by the increasing perfection of zoom lens technology. The days when you packed your camera bag with trusty 28mm, 50mm, 85mm, 105mm, and even 180mm lenses are rapidly disappearing. The truth is that, while the range of focal lengths may be increasing within a single zoom lens, no all-purpose lens is ever likely to perform at the level of equivalent When we plunge into photography with a zoom lens, the effortless continuum of focal lengths is apt to blur the distinction between photographs captured at different focal lengths. 50mm 28mm Open up a book on photojournalism and you'll discover a slew of images captured with wide angle lenses like the 28mm prime lens. Wide angle prime lenses have a remarkable pronounced curvature on the front lens element which helps to pull in light from all around the edges of a scene. Extremely short focal length primes, like the 8mm, are known as fisheye lenses because the angle of coverage exceeds 180 degrees. Using a wide angle prime like the 28mm becomes necessary when you try to capture images in confined spaces. 85mm to 105mm What does the ratio number mean? You might also notice a number written on your lens that looks like a ratio. This number refers to the widest aperture available for that lens. The lens in the example above can be opened up to f/4 at the widest end (17mm) but only f/5.6 at the longest end (85mm). Generally speaking, the lower the f number the better, because in low light situations the lens can be used to give a brighter image. The Recommended Camera Digital Lens for Professional Photographer I recommend you to buy Tamron AF 70-300mm macro lens. Tamron delivering superior image quality for both digital SLRs and 35mm film cameras, this flexible lens lets you zoom in extra close when shooting moving subjects, such as athletes on the field or children running or playing. When used with a digital camera, the lens does even better, producing a super-telephoto 35mm equivalent of 465mm--unbeatable in almost any other lens. 
prime lenses for its full range of focal lengths.
It used to be the case that the kit lens for a 35mm SLR was generally a 50mm focal length lens. Despite the fact that the 50mm kit lens has been replaced with an optical zoom lens (usually in the range of 28-80mm these days) the 50mm lens has a lot going for it. My 50mm kit lens (picked up decades ago) is an f/1.4 Nikkor. To read a fine essay on the under-appreciation of the 50mm lens, I recommend The Forgotten Lens by Gary Voth.
I have mentioned how useful the 50mm prime lens is for doing portraiture. The 85mm is sometimes referred to as a short telephoto. So to wrap up, I have summarized the characteristics and uses of several different focal length lenses.
For example 1: 4 - 5.6

Digital camera photos are usually stored on removable memory cards or discs. The storage capacity of these devices, as well as the camera resolution and compression settings, determines how many pictures can be stored on each memory device. Some early digital cameras stored digital images on magnetic disk drives or mini-CD drives. However, camera memory has evolved to the point where the SD card is arguably the most popular picture storage media today.
Strictly speaking, digital camera memory is where digital pictures are stored inside the camera. The digital camera memory is an essential and often a very neglected and overlooked section of equipments for digital photography and camera. There are many types of memory available for digital cameras, and it is a good practice to mull over what type of memory a camera uses before buying a digital camera.
Knowledge of the digital camera memory is very essential for using such a camera and capturing photographs. The most common form of such memory is a memory card. Digital camera memory is available in many shapes and facade depending on the type of digital camera that is being used and even and the number of pictures that are required to be stored in the digital camera memory.

If you are new to digital cameras, the digital camera memory cards are the most important parts of any digital camera, without which they may not work at all. Something many new digital camera owners find counter-intuitive is that bigger is not always better with a digital memory card. The speed that your camera writes new pictures to the digital memory card is partially dependant on the transfer speed of the digital camera but is also dependant on factors in the memory card itself. Memory cards that have “buffers” can take the data into a faster type of memory and then transfer the data from there to the slower “flash memory” which provides the main storage of almost all digital camera memory cards. Now the question arises-how many memory cards are enough for your camera? On an average basis, you must have at least two memory cards for your digital camera. Most professional photographers choose to carry about four to six memory cards. Now we can find 8 GB of Memory cards with a cheap price.
