The lens is an optical system that transmits light through itself into the camera, transmitting information about the subject. The clarity of the resulting image, the quality of the transmitted colors and shades will depend on the correct choice of lens. Beginners, when choosing such a device, should remember that the larger and wider the camera lens, the higher the probability of taking a high-quality picture.
The article is devoted to a brief overview of optical systems of the Canon brand. This company is one of the leaders in the production of photographic equipment. We will look at the line of the most popular optical systems among amateur photographers with a focal length of 50 mm for Canon cameras. These devices are most often used as portrait lenses.
Today, users are offered four fifty dollars with the following technical characteristics: aperture or aperture - ƒ / 2.5, ƒ / 1.8, ƒ / 1.4 and ƒ / 1.2. The first presented lens for Canon with aperture 2.5 is a rather specific device - this is a special macro lens. It stands out from the general range and has a rather narrow application, so we mentioned it in passing and will not dwell on it anymore.
Let's consider the most affordable lens for the Canon EF50 mm ƒ/1.8II. This device was released in 1991. It is characterized by average quality and, most importantly, low price. Thanks to these parameters, it is very popular among photographers. Even many novice amateur photographers can see these Canon lenses. Prices for such a device vary within 3000 rubles.
The described optical system has replaced the first version of the "fifty dollars" of the CanonEF system. These devices differ only in design, their optics are completely identical. The body of the lens is made of plastic, even the mount of the mount is made of plastic. For comparison, the first version was produced in a metal case.
The second lens under consideration for Canon is the EF50 mm ƒ/1.4USM. It is considered average in the line of "fifty" by Canon. This model is much better than the previous lens. The body of the device is made of stronger and better quality plastic, pleasant to the touch, the bayonet mount is metal. However, this lens for Canon has a significant drawback - a rather flimsy plastic "proboscis" that extends when focusing. Very often, due to problems with this element, the lens ends up in a service center.
Third suggested lens is the Canon 50mm EF ƒ/1.2L USM lens. FrameThe device is made of very high-quality plastic, the bayonet mount is metal. The lens has small overall dimensions, but the weight of the device is 550 grams. The body of the Canon 50 mm EF ƒ/1.2L USM is waterproof and dustproof. It eliminates the disadvantage of the first models, namely, there are no retractable elements. When focusing the lens, the front lens goes deep into the body.
This concludes our review of Canon lenses. It can be concluded that the optical systems of this company have very solid technical characteristics, they are able to compete on equal terms with all the world leaders in the production of photographic equipment.
