While every digital camera has a lens, digital SLR cameras have several lenses to choose between. Changing lenses is perhaps the biggest advantage of a digital single-lens reflex camera, particularly if you need wider, deeper, longer, closer shots, or even wish to shoot in low light conditions. If the primary lens on your camera isn’t suited for what you want, you can have the flexibility to simply replace it with a lens that is (but specialized optics aren’t cheap).
The Craze For Lenses
The term ‘lens lust’ is used on the internet often. It describes the state of dSLR owners who start thinking over and over about a lens that they don’t own. There is no lens that can take a perfect shot in every situation. The lens that probably comes the closest is a 18mm to 200mm zoom lens. This lens still won’t work optimally at all light levels and it won’t be able to provide ultra-wide shots or super-zoom capabilities. You have to think about what lens you need for a particular shot. Here are a list of items that a lens can do for you.Tip 1: Lens Varieties
The basic zooms in most digital SLRs have maximum apertures of f/3.5 to f/4.5, which is too slow in low light levels. Choose either zooms with f/2.8 maximum apertures or select fixed focal length lens with f/1.4 to f/2.0 even if you have to pay more. The most affordable are $100 or less which are the 50mm f/1.8 lens in most digital cameras. But if you can expend more money on your digital camera buy a 28mm, 30mm, 35mm, 50mm or even 85mm f/1.4 lenses that work well even in extremely dark conditions and are optimized to perform well wide-open.
Tip 2: Lenses For Increasing Sharpness
Lenses designed for producing sharp images will give you better results than a lens designed to do everything reasonably well. Your 50mm f/1.8 lens that only costs $100 might be the sharpest lens in your kit. Maybe you invested in a lens optimized for macro photography that is designed to produce extra sharp pictures at very short distances.
Tip 3: Wide-Angle Lenses
To get a broad view in your pictures, you should consider a wide-angle lens to get the job done. Using this lens lets you take pictures in a broader field of view- perfect for those times when there just is not room to back away from your subject. Your camera probably came with a lens that is no wider than the 28mm standard lens on a full-frame SLR. A dSLR combined with a wide-angle lens can enable you to get a wider look.
Tip 4: Telephoto Lenses
A telephoto lenses can capture images from much farther away. The average lens that comes with a camera usually provides 70mm and a crop factor of 1.5 providing a slight telephoto capability which is equal to a 105mm telephoto lens on a 35mm camera. You can find lenses that allow you to capture images from further away and they are fairly cheap.
Tip 5: Interchangeable Lenses
To give your camera great close-up capabilities, you can buy an interchangeable lens that enables the camera to focus on subjects that are a lot closer to the lens. This interchangeable lens literally opens up a whole new world of subjects that before could not be captured, as well as pictures of familiar objects taken ultra-close.
Tip 6: Primes And Zooms
The digital camera has evolved. Digital SLRs can use one of two basic kinds of lenses: prime lenses and zooms. Primes are fixed focal length lenses, and zooms are variable focal length lenses. Prime lenses were the best for sharpest, fastest optics, but today zoom lenses are faster, sharper and much more practical. Your lens kit will usually contain a few lenses of each type for the different uses of your digital camera.
Situations That Call For Lenses
When shooting architecture you need a broader range. In that case a wide angle lens will be needed, it helps you shoot without a tripod. With sports you may again need that wide angle lens to capture the image. From far away you need a fast telephoto prime lens shooting soccer for night games. A sharp short telephoto lens is used for taking portraits. When doing macro work a prime lens with close focusing does the job nicely. When decorating your home a wide angle prime lens creates a wonderful crisp image that can be blown up to a 20×30.
The Appeal Of Digital Camera Lenses
You can understand why people like zoom cameras. You can take pictures at different magnifications without moving about. Instead of having to use software later to crop the image, you can adjust your magnifications right there while taking the photo. There are many different zoom cameras. A zoom camera with a focal length from about 10-20mm or 12-24mm is known as a wide-angle zoom camera. These can be compared to a digital camera or full-frame film camera with a lens of 15-30mm or 18-36mm. These extra wide shots should only be used in certain instances so that a regular shot won’t look odd.
Carrying around multiple lenses is a pain. Having the right lenses on your camera to capture what you want is great. It’s important to know what lens best suits your photo-taking style however. Users of DSLR cameras need to be cautious about owning too many lenses, as one that simply collects dust is useless.
