Choosing DSLR Lens Guide | Tutorial Photography
Choosing DSLR Lens Guide – In the last article we talked about the type of DSLR lenses on the market, and it could be the beginning to answer the following question: Which lens should I buy? Tutorialphotography.com In this article will discuss some of the factors for consideration when going choosing a DSLR lens. Each of the features below will be different in each lens.
The speed of the lens could be the subject of when you are looking for a new lens. Speed ??or how fast a lens is actually closely related to the maximum aperture is owned by the lens. Aperture is the size of the lens aperture when the shutter button is pressed (or how much light enters the camera). Aperture is denoted by F (f-stop).
you can read our article about the aperture at: Understanding Aperture in Photography. The smaller the number the bigger the hole, and there will be more light coming in at one time. This means the shutter speed becomes faster, the reason why the term ‘fast’ or ‘faster’
The magnitude of the maximum lens aperture can help you in several ways, among others:
Lens “fast” with a maximum aperture of f/1.4 allows you taking place relatively dark compared to lenses with a maximum aperture of f / 4 or f/5.6. It does not make a slower lens to be bad, but it deserves to be known.
The lenses are “faster” allows you to retrieve the object motion and photograph without getting motion blur
Lens “fast” allows you to get a depth of field that is thinner / narrower. This means that when you focus on a subject in the foreground the background will be blurry or out of focus. It has a lens ‘fast’ of course means it is possible to focus a little more ‘tricky’, given the depth of field is used very thin / narrow. For example, when photographing portrait of a face with f/1.4 aperture and focus on the eyes, then most likely you will find the nose a little out of focus.
The lens ‘fast’ usually tend to be more expensive than other lenses slower.
The lenses are more “fast” would be helpful in terms of flash photography in recording or taking ambient light
As a reference, the speed of the lens with the aperture of f / 4 is usually good for general purpose photography with good lighting conditions. f/5.6 requires good lighting or features image stabilization (IS / VR), if you shoot indoor without flash, then at least use a lens with f/2.8, and if you shoot indoor sports then at least use f/2.0 or even ‘faster ‘out of it.
Focal length is the length of the lens you are using (the unit is the unit of measurement mm focal length of a lens). This measurement is the distance between the middle of the optical lens to the focal point on the camera sensor. What you should know is that the focal length of a lens inform you how much when shooting subjects will be enlarged. Focal Length also inform the angle of view that you can.
This is the measurement between the end of the lens with the closest point focus capability. This is useful when shooting in macro or close-up photography, considering the type of photography requires a very close distance to the object image.
Most DSLR lenses is now equipped with image stabilization (IS known as the canon, and the Nikon lens known as VR). This feature is useful for minimizing vibration or shaking the camera (Camera Shake).
Camera Shake is a movement that occurs when the shutter is open. This incident had a greater impact on the photos when we use slow speed, do not use a tripod and use a lens with a longer focal length.
Each lens and camera has different types of IS, but most DSLR lenses to feature contains gyro sensor that is able to correct any camera shake. We also do not really understand the mechanism of this IS but certainly all Canon or Nikon lenses that have this feature allows us to take pictures with just holding the camera (without a tripod) and a slower shutter speed.
IS helps photographers reduce camera shake at low light levels, but still it does not freeze (freeze) the subject is moving. Basically IS allows us to take photos at lower shutter speed which the camera aperture open a little longer, but if the subject of the photo you mean move will lead to more blur.
IS features mean additional cost on a lens, so you need a consideration of whether the activity of shooting with lenses that require this feature or not. example: whether you are shooting in low light conditions by using a long focal length without a tripod?
Materials and Quality Lenses
The lens has a lot of variety in terms of quality of materials and construction. you can tell by holding the two lenses of different lenses and feel its weight. For example, the Canon 50mm lens (f/1.4 and f/1.8), there is a striking difference in the two lenses is related to the weight and materials used. 50mm f/1.8 lens has a dominant material with plastic than 50mm f/1.4 lens.
Most lens manufacturers have different levels of lens. For example, at the level of Canon’s existing lens series called ‘L-Series’. you can easily recognize it from a circular red ring on the lens body. L-Series lenses are designed with luxury and quality reserved for professionals, and using glass optical elements as well as high quality. These lenses are generally heavy, quite ‘fast’, the focus is fast and can produce pictures of remarkable.
Review the above does not mean that this lens is perfect for everyone. consideration of the budget for a photographer and trust also play many other lenses that can produce good photographs.
Considerations in buying lenses when going to upgrade is the cost. Most people did agree that “we get what we pay”, and we prefer to upgrade the lens than the camera body to replace (depending on conditions). A little wary of the ‘kit lens’ built-camera guys. In many circumstances these lenses are good, but we think it would be better if we buy only the camera body and then choose a better lens than the kit.
a lot of arguments surrounding the use of lenses that to produce good photographs we have to stick with the same brand lens with the camera, as opposed to using a cheaper lens like Sigma, Thamron and others. according to us for the first time try to find the same brand lens and if you do not find it then try a third party lens. Experience shows that all of the manufacturers or brand lenses have good and bad lenses on the market. Do research on the lenses before buying. There are many websites and forums that provide a review and comparison.
