Choosing a CMOS Camera: Key Features
There is a revolution in the film industry happening right now that many people are not aware of, and it's being caused by CMOS cameras. Cameras used for still photography are changing the motion picture business. It began with the Cannon EOS 7D--a digital camera that uses a like CMOS sensor that is superior to many professional video cameras. In fact, it can shoot HD that looks just as good as the video you see on television. When CMOS cameras first came out, they were inferior to the established ccd digital camera models. Now, they're surpassing them. Here's what to look for when choosing a CMOS Camera.
SLR cameras have existed for years in the 35mm world. What has always made them great is the ability to change lenses quickly. Changing lenses to different focal lengths creates superior images over those shot with zoom lenses because the depth of field is greater. The SLR model was carried into the digital camera world and represents the highest quality camera that one can buy. If you're considering a CMOS camera, then see if you can afford an SLR because they are the best.
Because the technology is advancing, you should try to get an SLR that shoots 30fps HD video. That way, you have both a high quality still and video camera. It's important that it is 30fps. Some cameras advertise 3fps HD video, which will not play back like the stuff on TV.
With CMOS Sensors, Size Matters
The larger the sensor, the high quality of an image captured. The size of the pixels is physically related to the size of the sensor. When comparing models, get the one with a larger sensor because you will notice a difference. Cameras with small sensors suffer from noise problems in low light. A large sensor will reduce those problems. It might cost a little more to get the camera, but you won't regret it.
ISO levels determine how sensitive the sensor is to light. Usually a higher ISO level is used to compensate for a lack of light, but this creates a lot of noise in an image. When buying a CMOS camera, take several pictures in it at various ISO settings and compare the quality. You want a camera with which you can take great photos in low light levels.
Play with the shutter speeds too. Sometimes a slower shutter produces image noise. If the camera you were thinking about buying does this, then just move on to the next one.
