Sony A550 of digital camera reviews
   Published in 2009, the Sony A230 and the A330, a lot of people are wondering, Is this the Canon 500D competitors? Clearly, the seasoned SLR market, Sony’s entry-possession after the strokes, the author is that this fall in the hands of the Sony A550 SLR real “strength of the for.” High-pixel Exmor CMOS sensor, high-resolution screen and the high turnover rate of the burst seems to presage the arrival of entry-SLR market storm.
  50mm standard lens commonly known as the “header”, using the A550 such as the APS-C frame camera, 50mm lens is converted to 75mm lens, suitable for shooting portraits. Sony DT 50mm/F1.8 with a large aperture is such a high cost-effective header.
  Sony A550 + DT 50mm/F1.8 the combination of the resolution made a very eye-catching results. When the lens aperture be reduced by about a file to F2.8 when, DT 50mm/F1.8 who showed great strength, until the resolution of the entire system when F8 results are in 2700LW/PH around, this is basically already played out Sony A550′s all the strength.
  In this session, we CBSi China’s digital imaging lab, using a constant light source for indoor lighting, the use of the Sony A550 opposite the still-life sets to do the shooting under the ISO file to record parameters and interception of pictures taken of representative parts of the final sensitivity to the interception of the picture under a different comparison conclusion. In view of fixed-focus lens has a more stable image quality, so this part of the evaluation of the objective test we have chosen the Sony A550 + DT 50mm/F1.8 combination.
  As the use of CMOS sensors, Sony A550′s take-off point set at the sensitivity and the Nikon D90, D5000 and other similar ISO200, while the A550 upper limit of sensitivity was amazing ISO12800. Taking into account the effect would not have significant differences in quality, so A550, Sony canceled the expansion of income ISO100 sensitivity.
CMOS sensor in noise control is indeed tough, compared to 14 million pixels is also the use of CCD sensor Sony A350, A550 in the effect of noise control has made substantial progress. In the ISO 400 or even ISO 800 the next, A550, and the quality are comparable to ISO 200, but not until ISO 1600, the Sony A550′s photo quality is only slightly.
If the environment requires the use of A550 must be the ISO3200 sensitivity, then reduce the size, its effect is still good. As for the next ISO6400 and ISO12800, is basically do not have practical value, is only a way of display technology vendors only. It is true that a year ago, if you think that Sony’s entry-level camera’s ability to control noise slightly less than the competition, then the A550 is the emergence of this situation has changed, even, and a popular Canon 500D or Nikon D5000 La Xiafeng than not.
  If the early years of the Sony A100 is testing the waters, A200 towards maturity, then the new Sony A550 and A500 can be regarded as real and Sony, Canon, Nikon, Pentax, oba, the strength to fight the guy. This is, from the A550 at about 5,000 yuan a target price, we will be able to see that Sony have chosen this time with their own entry to tackle the flagship Canon EOS 500D. Why Sony A550 on the straight of “Yao Gan,” what is it backed it for the A550?
  SLR market, the three pillars of the A900 was born as early as when the trend had been established, in the Canon, Nikon, Sony, these “three” SLR makers, only Sony uses cost-effective body Anti-Shake technology. May be at an early stage can not see the benefits of body image stabilization, but once the game of “deep”, and Canon, Nikon 2 the price of expensive anti-shake lenses is not a small number of cost to Walsh said. So to say that Sony and the two largest capital to compete, or to say that very early on with sensor shift image stabilization technology.
Sony is relatively N, C (Nikon, Canon) Another big advantage is its unique use of technology, real-time viewfinder. Co-ordination of flexible, high-resolution screen, flip, Sony A550 is equipped with fully SLR focusing speed and DC framing flexibility.
Observant friends may find that the above two technologies from Sony, the A350 is to have the time, why then A entry SLR there is no “fire” together? Relative to the established vendors, Canon, Nikon, Sony, the lens number, especially in low-cost high-quality lens in absolute numbers disadvantage, which limits the A-series entry-point play to the camera, while the previous generation of Sony’s entry-SLR cameras more or less competitors in quality and in some gaps, but also led to a certain extent.
The CMOS used for the A500 and the A550 not only in picture quality has improved, and along with 50mm/F1.8, 30mm/F2.8 macro ,18-55mm lens set of first-class series of high-cost market, in the low-cost The number of the lens, the Sony in 2009, has also made a substantial growth.
We go back to A550 body, with the high-performance real-time viewfinder, body image stabilization has two advantages, combined with quality, the lens group 2 “short board” perfect, A550 is no doubt on the overall competitiveness has been greatly strengthened. Some say: SLR camera system to fight the overall strength. This statement will be justified, even in focus, white balance, there is still room for improvement, even when you do not have the A200 listed on the “price butcher”, but the author of the Sony A550 is still optimistic. Because we can see is the overall A system upgrade, you can see is the N, C, S – Nikon, Canon and Sony really big battle between the beginning.
