Your lens is an significant element to good photographs. It's not just your camera. Population spend thousands of dollars on a good camera and neglect the lens.
[b]Lens[/b]Change that around! Make sure you buy a good camera lens when purchasing a camera. Buy a good camera as well, but don't neglect a good camera lens.
Why? Your camera is just the 'holder' for the photograph. The lens is what your camera sees all your shots through. A good lens is significant to clear and sharp photos.
With most covenant digital cameras, you can't turn the lens. So in that case, don't just buy a good camera, ensure it also has a good lens.
Avoid a plastic digital camera lens because it doesn't have the clarity of a glass lens.
What model of lens?
Stick with camera lenses from well known manufacturers like Nikon, Canon and Pentax. Ensure you purchase a lens that works with your camera too. A Nikon camera lens ordinarily won't work well with a Canon camera.
There are specialty lens manufacturers like Carl Zeiss, Leica and Leupold. If you're a beginner, don't worry about these lenses until you are more advanced as they come with very high prices and it's hard to by comparison the price for the small increase in quality.
Types of Camera Lens
The most common lenses are : Wide Angle, general and Telephoto. The type of lens is carefully by the Focal distance of the lens. See below. A Zoom Lens is plainly a lens that can turn Focal distance from a Wide Angle to a Telephoto (or somewhere inbetween).
There are a estimate of things to look for when purchasing a camera lens.
Lens Focal Length
The Focal distance of a lens determines the estimate of magnification and angle of vuew the lens can see. The Focal distance is measured in mm. It's the Focal distance that determines if the lens is a:
- Wide Angle; small magnification, wide angle of view. 20mm to 35mm
- Traditional, or Normal; 50mm
- Telephoto; high magnification, narrow angle of view; 105mm to 300mm.
- Zoom; A Zoom lens can turn it's focal distance to zoom in. A Zoom lens might have a Focal distance of in the middle of 50mm and 150mm.
Some lenses are interchangeable in the middle of film cameras and digital cameras, but you need to be aware that the effective focal distance Changes in the middle of film and digital. The focal lengths I recapitulate above are for Film cameras and need to be multiplied by 1.6 to get the effective focal distance on a digital camera. So using a film 35mm lens on a digital camera has an effective focal distance of 56mm.
What does this mean for you? It means that you won't get as wide angle on a digital camera as you would on a film camera using the same lens. A 35mm lens which gives a medium wide angle on a film camera acts as a former lens on a digital camera
This is a complicated subject, so I can't go into too much information here. If you need more help, the best man to speak to would be your local camera store's resident expert.
Lens Speed
The 'speed' of a digital camera lens also defines a lens. The speed is carefully in f-stops and is similar to the f-stop aperture setting on your camera. Faster lenses are more expensive and ordinarily heavier.
Focusing Distance
This is the minimum distance from the camera lens that a branch must be to be in focus. Don't worry about getting a camera with a close focusing distance. Concentrate on a telephoto instead.
More advanced Features
More expensive lenses have more advanced features.
- Vibration Reduction. A highlight called 'vibration reduction' keeps images sharper when shooting in low light. They help to counter any vibration in the camera. Try to find a digital camera lens with this feature.
- Usm Usm stands for Ultrasonic Motor. This highlight of Canon lenses gives you a high speed auto focus but the main benefit is the 'motor' is roughly silent, so you don't disturb Population around you when your camera is focussing.
- Filter Thread. When purchasing a half-decent lens, it should have a filter thread. This is a thread that allows you to screw on a filter (such as a polariser) to help when photographing difficult situations. Even if you don't need filters right now. It's handy to purchase a lens with a thread so you can add a filter later.
You get what you pay for
Generally the more expensive the lens, the better it is. More expensive lenses ordinarily have a higher estimate of glass elements in the lens, which also makes them heavier.
Final Notes
While it is prominent to pick good potential camera lens, for beginners it isn't as prominent as good composition. Don't fall into the trap of mental you can only take a great photo with an expensive top-of-the-line lens. A badly composed photo won't look great with a great camera lens.
I don't mean to allowance the significance of a good potential lens. A good rule is to only add to your lens variety only when you have a specific need for a singular digital camera lens.
Do your investigate and your homework first, and find the lens that suits both you and your camera.
