Canon PowerShot A20 - review
 Canon PowerShot A20 - review |
Time of purchase: mid-April 2005.
The strengths of the Canon PowerShot A20: Excellent picture quality for a camera of this age and this "megapixel" rating. Good color reproduction. AA batteries. Convenience, unpretentiousness.
Weaknesses of Canon PowerShot A20: Lack of manual settings, except exposure compensation, white balance and a few flash modes there is nothing. Does not shoot movies. Lack of macro photography. What this camera calls "macro" mode, is really a mode "a little closer".
Used analogues: I have used Canon A60, A95 and Kasio QV3000 for a bit.
In general this is my first camera.
The comment: I bought my Canon PowerShot A20 rather second-hand camera as "so as not to be afraid to ruin it". The quality of images pleasantly surprised. White balance is rarely wrong. The camera is quite reliable. I've been in a kayak, got sand grains on it - nothing so far. Obsolete, of course. The impossibility to shoot a bug or a blade of grass is a little depressing. I wish I had manual settings. However, I am more than satisfied with this camera for the first time. Later I will look for something more functional and expensive. I give it 4 only because of its "ancient" design flaws. In its class (very old and cheap cameras) it is undoubtedly one of the best.
It is no secret that professional photographers prefer SLR cameras. And there are many reasons for that. In this article we will tell you about the features of SLR cameras and what you should pay attention to when buying one.
SLR cameras, unlike soap operas, have a bigger sensor. The size of the sensor has a direct impact on the quality of photos. SLR cameras also have interchangeable optics, allowing the photographer to choose the most suitable lens for the specific purpose. In order to take pictures with an SLR, you do not need to be a professional photographer. The automation of the camera allows you to get high-quality pictures with minimal effort on the part of the user.
Description Canon PowerShot A20. The camera has several features: the body made of plastic, power through a 4-cell "AA", the ability to equip the camera nozzle lenses and filters after removing the decorative ring around the lens shaft and the installation of tubus adapter, located directly above the lens "pupil" telescopic viewfinder, reducing the effect of parallax, unusual for the series PowerShot ledge to keep the right side of the body, remote from the lens emitter flash, reducing the chance of "red eye" in the frame.
Usually, the electronics of SLR cameras are better than those of soap operas. And the processor, which is the brain of your camera, is no exception. Comparing processors from different manufacturers is difficult, as their specifications are not published. Moreover, the processor can not operate without the software, which is also closed and specific to each brand. The camera software allows you to do image processing and has a lot of settings.
Processors can be compared by how different cameras handle processor-dependent operations. For example, how fast a camera can shoot a series of photos, or how quickly a high-resolution photo is recorded to a memory card. The electronics of SLR cameras are much more powerful than those of compact cameras.
Basically, the design of a digital camera repeats that of an analog camera. The main difference between them is in the photosensitive element on which the image is formed: in analog cameras it is a film, in digital cameras it is a matrix. The light falls through the lens onto the sensor, where it forms an image, which is then recorded in memory. Now let's look at these processes in more detail.
