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.

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 ).

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?
