Tips to understand and mix and match between the digital SLR camera with a lens as needed.
If you are a beginner in the world of photography you may want to soon have a new lens than the kit lens you already have. Before you buy a lens, you make sure the field of photography to be your field, whether traveling or photography landscape photography, architecture, macro photography, photography for weddings or journalism photography. If you already understand how mixing and matching between the lens and digital SLR camera, then you do not need to carry a camera, and lens equipment as a photographer in this photo.
Lenses can be categorized into several classes based on specific categories, which include:
Focal length
The shorter the focus of an increasingly wide-view lens obtained, or also called wide angle lens / wide angle lens. The focal lengths of the lens while the narrower point of view but the higher magnification of the recorded object, or often referred to as the zoom lens. Judging from the focal length and usefulness, we can categorize the lens into several classes, among others:
Wide and ultra wide angle lens
This lens has a focal 35 mm or shorter. The wider the angle of view lens more the objects recorded, this type of lens is perfect for photographing landscapes (landscape), buildings, activities that involve a lot of people like the traditional ceremonies, dances, or a large family photo. In addition to the wide angle lens is very useful when you are close to the object that you want to photograph. These lenses also provide 3-dimensional effect on the resulting image.
Standard lens.
Has focused 50 or 55 mm, this lens is usually the lens is also an innate / kit lens when we buy a new camera. This type of lens is suitable for day-to-day needs in the photograph.
Telephoto lenses.
Focal length lens (focal length) lens ranges from 85-200 mm. Long enough for you to take pictures of objects that are not too close to you, for example, a candid photograph of children who were playing without disturbing their game, or focus on a candid photograph dancer dancers among others.
Super Telephoto lens.
With a focal length of 300-800 mm, extreme lens is suitable for taking pictures of wildlife such as birds were in the nest, or maybe even photographing wild animals even without having to reposition ourselves in danger with him. This type of lens is also frequently used in the world of sports. High cost and the long form and weight makes this lens is usually only used by serious photography enthusiasts.
Fixed Lens and Zoom Lens.
 |
Fix focus lens has a fixed value, or more simply the lenses cannot be used to zoom the object, meaning that you have to run toward or away to zoom in / out objects. The advantage of this lens is smaller than the zoom lens, as well as the results obtained sharper. Fix lens also has a wide opening so as to produce the effect of blur / bokeh better. Zoom lens has a focal range of purposes, such as focusing lenses 18-135 mm. Excess is the flexibility of zoom lens, the one we can get focus lens for wide angle and zoom lenses as well. The disadvantage is the large size and sharpness quality of the results obtained are still below the fixed lens.
Fix & Variable Aperture
Some lenses are also made with a fixed aperture, with aperture diaphragm that cannot be changed. Lenses like this are usually worth relatively expensive compared to lenses with variable aperture (aperture change focal length follow-fox)
Fast Lens.

Important note before buying lenses:
So how do we choose the lens? The first of course to ask yourself what you need. Is it only for the purposes of taking a trip with a holiday or special interest such as photographing landscapes (you need a wide angle lens or zoom lens), or the wild life (requires a telephoto or super-telephoto lens).
Some other tips and solutions that you can consider before buying lenses include:
1. Faster lens is better than a slower lens. Choose a lens with f values as small as possible.
2. Lens with a fixed aperture (f value is fixed) is better, although these lenses are usually high-priced.

4. Consider also the quality of the lens material if you have more funds. Some upscale lenses are made with good materials and even resistant to weather changes.
5. Before buying a lens, make sure you choose the lenses fit your budget and needs. If your budget is not enough to buy the original lens (OEM) in accordance with your camera, then you can buy a used lens or third party lenses manufactured by Sigma, Tamron, Tokina or Samyang. Now Tamron, Rokinon or Sigma lenses have been produced specifically lenses for Canon, Sony or Nikon with good quality. Tokina and Samyang also have been producing high quality for the special and specific needs. If the Sigma and Tamron has produced almost all types of lenses, the Samyang and Tokina make lenses more unique that may not have been made by Canon, Nikon, Pentax, Sony or other lens factory like Rokinon, Carl Zeiz, Leica, Olympus, and Panasonic or by Sigma and Tamron.
If you are serious about photography, then you will find many kinds of lenses such as fish-eye lens, lens baby and forth like a lens to the needs of the police investigation at the crime scene, the lens for photos of stars, and the lens to support the military, scientific and lenses to science knowledge.

Simple tips for choosing lenses for DSLR cameras
 |
| Lens for Canon DSLR cameras. Image: oneslidephotography.com |
If you'd like to understand more about different types of lenses and how they're described, so you can choose the best Canon lenses, best Micro Four Thirds lenses or best Nikon lenses.
It’s important to remember most camera companies employ their own unique lens mountings, which means one company's lenses generally won't work on another company's cameras. You can start from the basic. It’s a good idea if you buy a standard prime lens. A prime lens is a lens that has a fixed focal length. A 50 millimeter prime lens is the perfect starter lens. I know that you already have lens kit 18 – 50 mm lens when you bought your first DSLR camera.

There are two fundamentals that we should understand before you buy new lenses: Firstly, focal length and sensor size.
Every lens is defined in millimeters, and this measure is called its focal length. This measurement is the distance between the sensor and the optical centre of the lens when the lens is focused on infinity. It's important to know the difference between zoom lenses and prime lenses. The zoom lens is allowing you to magnify your subject.
A prime lens can't zoom such as a 50mm lens which is good to create portrait. You need a zoom lens to capture sport activities, holiday or when you go to the zoo to capture the dangerous animal such as lion or gorilla.
A good zoom lens is a 50- to 250-millimeter zoom, however you can choose an 18 – 200-millimeter zoom that made by Canon, Nikon or other third party manufacturers.
Please remember if you're buying a Canon lens for a Canon camera, that's a pretty good indicator that you're on the right track. However, if you're buying a third-party lens, you'll want to be sure the lens is intended for your brand of camera. There are good third party lenses that made by Tamron, Sigma, Samyang or Tokina. They made special lenses for Canon and Nikon, so please make sure that you choose the right type lens before you decide to purchase a third party lens. A good zoom lens is a 50- to 250-millimeter zoom. You can use a zoom lens to take photos in a wide shot to a close-up, however the best portrait is always fantastic if you capture with a 50mm lens, a prime lens.

Before you go to camera store don’t forget to consider is the image sensor in your camera. There are basically two different sensor sizes; “Full frame” sensors, which are the same size as one frame of 35mm film, like those in traditional film SLRs; these are generally in higher-end cameras. Another one is the smaller image sensors, like those found in most digital SLR cameras such as Nikon D5300 or Canon EOS D700. The full frame cameras such as: Nikon D800E and Canon EOS 5D Mark III or Sony Alpha 99 (SLT-A99V).
If you are serious about choosing lenses, you may need to have atelephoto lens forportrait photos to make the resultsmore like an amazing85 millimeters, totake portraits orto get closershots of distantobjects without movingthe camera. This lens is also good to use when you want to photograph beautiful birds in the trees, orsteal a photo when you see a beautiful girl in the distance, then youcan make close tothe face of the girl with a telephoto lens without being noticed by the girl.
If you are interested in photographing small flowersor insects that was perched on a flower, then you need a macrolens, but the lensof your camera kitis also quite goodfor this sort ofpicture-making. Would you like to vacation andsee landscapes likeforests or mountainsin the distance and the beach? If you have enough money, then you need to have a wide angle lens. And you should apprehend that for a very wide, please go with an 18 millimeterlens. However Forjust a little wider than the 50 millimeterlens, use a35 millimeter primelens.

Although the Sigma camera are not as famous as Sony or Olympus cameras, but you certainly will be amazed with this new camera, the Sigma DP2 Quattro and other Quattro series.
By making the Sigma DP Quattro, perhaps Sigma wants to solidify its image in the world of photography, then in addition to successfully create various types of lenses, the Sigma also able to make digital cameras such as Panasonic, Pentax or Samsung. Sigma DP series is launch 3 series; The DP Quattro series will Consist of three models: the DP1 with a 28mm fixed focal length, 45mm at DP2 , and DP3 at 75mm (35mm equivalent all ).
All lenses have an aperture range of f/2.8-16, DP1 and DP2 with the having a nine - blade diaphragm and a seven - blade diaphragm in the DP3. Lens construction is nine elements in eight groups (DP1), eight elements in six groups (DP2), and 10 elements in eight groups (DP3).
The lens specifications, in terms of numbers of groups and elements, and minimum focusing distances, remain unchanged from the 'Merrill' models. All three models will have 920k dot rear LCDs and 9-point contrast-detection autofocus systems. You can enjoy improved optics, ISO performance, image processing and design.
Works of art camera
The Sigma DP Quattro is redesigned in every aspect, including the sensor, engine, lens and body, the DP Quattro Compact Camera series embodies Sigma’s philosophy of creating cameras that produce works of art. If you look the specification, then the cameras are similar to the Sigma Merrills, - fixed 19mm, 30mm, and 50mm f/2.8 lenses paired with Sigma’s unique Foveon APS- C sensor - but the industrial design is a radical departure from anything else on the market. The Sigma DP2 Quattro is the next generation of its DP series of APS-C sensor, fixed focal length cameras. The latest, 45mm-equivalent, model features dramatic styling and a fundamental re-think of the company's Foveon multi-layer sensor design.
Sigma has always released its compacts in trios: same camera, different prime lenses. The 1st of the three new Quattro cameras will be released with a 20 MP Foveon X3 sensor, the new faster True III processor and a 30 f/2.8 lens attached. Sigma has also made a leap to a faster TRUE III image processor. There is another surprise that you will find, there's also an opticalviewfinder available for purists, which should work well with the fixed lenses. The DP2 Quattro will come with a 30mm f/2.8 general purpose lens, while the DP3 and DP1 will respectively carry 19mm wide-angle and 50mm telephotooptics. The image quality that Foveon chips output is incredibly detailed. The new Foveon X3 Quattro offers an even higher level of image purity with a 30% increase in resolution to the previous Foveon sensor, sure to bring about new experiences in your photography.
If you look at the shape of this camera, very different from the previous Sigma cameras, even appears in contrast to the compact-system camera ever you known, with a very unusual shape. You could also say that this form of the Sigma DP Quattro has almost cinematic body shape is meant to provide a more balanced feel in the hand than the compact design of its predecessors. The camera has a wide, relatively thin body with a grip that bends backwards at about a 45-degree angle.

The camera is made by Sigma is different from other cameras, Sigma's cameras use a technology called Foveon. This special sensor has three layers, with each layer sensitive to blue, red or green. This way the camera has color information from all three channels at every point in the frame. The result is generally a very sharp, very large image. Autofocus is greatly improved, continuous shooting times are a little more usable, and the battery life has more than doubled. The Quattro models will also see vastly improved battery life when compared to previous DP-series compacts.
If you are interested in the sophistication of the camera sensor and lens on the Sigma DP Quattro, then what series would you choose out of the three?
