The lens of the camera – Zoom Vs. First
The first thing you need to decide to use when purchasing or setting a goal, you’re a zoom or fixed focal length. In other words, a fixed lens with focal length. Zooms May resemble the obvious choice for many because you get all the different focal lengths fall within its scope a year and the goal itself. It is very flexible and you do not lose contact lens wear time and a lens to another. Do you want to capture the beautiful landscape? Zoom out and click. Want to capture the facial expression of someone? To enlarge, click. These are certainly great advantages over the first lens, where you sit with the same focal length. But Prime Lenses have their advantages. In general, they are smaller, faster, cheaper, sharper, less distortion and less susceptible to damage than the zoom. Suddenly worth considering, is not it? Let’s take a look at first. A quick goal, you say? Objectives first are not as many goals (glass) will regard them as zoom Lenses. And that’s the key, they are simple constructions, and thus is smaller and less expensive. Well, that is with prime numbers too quickly? This is another piece of glass, is not it? Not a racing car! Well, when photographers talk about a lens to be fast, it’s really rather meaningless. What they should say that the target is a large aperture, which allowed more light to pass through the lens, so the camera quickly to nail the correct exposure. It is easier to say that “the objective is fast!”. If you’re one of those “target speed” gives you some options. You can easily freeze and capture high) action situations speed (large aperture and fast shutter speed and you can take a hand-light) images in low light conditions (openness and speed of slow shutter. Please note that if you use a large aperture, the sharpness of the “depth of field (is) smaller. Things will be a point behind your focus will be blurred. This is not necessarily a bad thing, but it can help draw attention to the main subject of your photo and away from background clutter. Using the length more openness and more lens you are the smaller your field of intervention. But back to the first Lenses are simple constructions, other advantages mentioned above, I finesse their upper and lower distortion. In particular, the sharpness, it may be useful if you plan to submit pictures to a photo agency. Sale 10 to 20 images mega-pixel is an outstanding performance from your goal. Finally, because the lens can zoom First, there’s one thing less that can break choose between zoom and prime numbers is not always so simple. In addition, some people believe that single focal length primes severely limited, while others consider it liberating they have one less thing to think to find. Personally, I use both zooms and primes. When I arrived in a rapidly changing situation where the things around me, I prefer the flexibility of the zoom. But when I go out shooting with a peculiar expression in his eyes, I prefer to use the appropriate range or prime lens length.
