For the past few years, Canon has continued to produce bulky SLR cameras while competitors have been busy selling mirrorless products. As it turned out, all this time, Canon did not waste time in vain, but for a long time meticulously prepared its completely new device, which can make a splash in the world of photographic equipment. Meet – the first mirrorless camera manufacturer Canon EOS R.
Appearance and design
Case Canon EOS R turned out to be unusual, having almost nothing in common with previous models. It is made of strong and at the same time lightweight magnesium alloy – the weight of the camera is only 660 grams. The camera is protected from dust and water, so the EOS R can be taken for shooting in almost any weather. Canon also introduced a simple but useful feature: in the off mode, the camera shutter is lowered, and the likelihood of dust entering the lens is minimized. Continue reading
The history of Polaroid began in 1922 at the Mouven Summer Camp for Boys, which was located on a lake in Connecticut. Barney Griden worked as a mentor in the camp, he was passionate about physics and later patented eight inventions for scuba diving.
Barney demonstrated scientific experiments to teenagers, woke them in the middle of the night to show a thunderstorm and explain its nature. Seen experiments so influenced his students that in the future many of them took up science.
The most famous among those students was Edwin Land, he patented 535 inventions – only Thomas Edison received more patents. Land’s inventions include a polarizer, an X-ray film, 3D films, night vision devices for the army, and much more. The scientist led the development of the U2 spy plane when he was an adviser to U.S. President Dwight Continue reading
Now let’s talk about some parameters of digital video cameras that can still be used as selection criteria.
Number of CCD
Perhaps this is the parameter, at a glance at which two or three years ago, the class of a video camera immediately became clear. Now, the mere fact of having three CCDs in an amateur camcorder says almost nothing. For cameras with three matrices, using a special prism, the image is divided into three primary colors, and each color is transmitted to its own CCD matrix. It is clear that in cameras with three CCDs in most cases an optical stabilizer is used. Only in recent years, Panasonic began to produce 3-CCD cameras with electronic stabilizer, then this “initiative” was picked up by Sony. Continue reading
