Canon 50D digital cameras

Canon 50D digital camera performance details:
 In the Canon EOS 50D package contains a Canon EF-S 18-200 1:3.5-5.6 IS lens. This is one of about 11 with a performance of portable optical zoom lens, lens body with plastic material, the lens has maximum aperture is only F3.5-F5.6, therefore, the lens shape can be so small, more conducive to the portable and tourism. Coupled with IS optical image stabilization unit to join, so that The lens to become a well-deserved “Travel God Mirror.” Behind the mirror side with focus mode switch lever, and anti-shake feature, through the AF / MF select automatic or manual focus; open the anti-shake feature, in the viewfinder can be clearly felt in the presence of anti-shake feature, intuitive visual experience for our hand-held shooting under low-speed shutter to increase confidence.
  Anti-shake image stabilization lens effect is always a limit, at a certain shutter speed can play within the anti-shake effect, but not a substitute for a tripod for long exposure. And this limit is also a measure of an anti-shake lenses important parameter. Canon EF-S 18-200 1:3.5-5.6 IS lens which claims to have four shutter speed slower than the safety of the anti-shake effect, while the actual test results in turn do? We use the Canon EOS 50D shutter speed from a security shutter speed to reduce the entire file to 1/2s up. In each stall speed, we use the EOS 50D were taken of the opening and closing image stabilization of the proofs. Shake Reduction test results from the view, open the anti-shake, the Canon EOS 50D kit lens 1/15s shutter speed at the telephoto side when you can still get a clear, practical picture. In the safety of hedging Tele 1/200s shutter should be about. By this calculation, EF-S 18-200 IS lens can provide about four times the anti-shake effect.
  Canon EOS 50D has a 15.1 million effective pixels, image quality is also a quasi-professional SLR level, while Canon EF-S 18-200 1:3.5-5.6 IS lens is somewhat worried that a focus with USM ultrasonic motors are not equipped with Great light changed, the resolution of the performance of small-aperture lens can do to make most people satisfied. CNET China, our digital imaging lab, respectively, the lens wide-angle end and telephoto end of the resolution test, and compile into the following chart to illustrate to do. The optimal parameters for the largest shooting JPEG formats, automatic white balance, aperture priority mode, ISO100. Canon EOS 50D kit lens wide-angle end of the performance slightly better, at F5.6 peak appears under Resolution 2550 LW / PH, while most aperture resolution under the test are also around 2400 LW / PH, the overall performance is satisfactory . In contrast, the lens telephoto end of the ability to distinguish a bit weak, the peak position is also found in F5.6, and as a narrow aperture, the lens resolution, progressively decreasing. Peacetime use, such as the effect of the background without much consideration, we will be fixed at F5.6 lens aperture location can get better results.
