Lens for Canon: an overview

The lens is an optical system that passes through the light into the apparatus, transmitting information about the object of photography. From the correct choice of the lens will depend on the clarity of the resulting image, the quality of transmitted colors and shades. For beginners, when choosing such a device, it should be remembered that the larger and wider the camera lens, the higher the probability of making a high-quality picture.

The article is devoted to a brief overview of Canon's optical systems. This company is one of the leaders in the production of photographic equipment. We will consider the line of the most popular among photographers of optical systems with a focal length of 50 mm for Canon cameras. These devices are most often used as portrait lenses.

To date, users are offered four "half-ruble" with the following technical characteristics: aperture or diaphragm - 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 fairly specific device - it's a special macro lens. It stands out from the general series and has a rather narrow application, so we mentioned it casually and we will not dwell on it anymore.

Consider the most affordable lens for Canon EF50 mm ƒ / 1.8II. This device was released in 1991. It is characterized by medium quality and, most importantly, low price. Thanks to these parameters, he enjoys great popularity among photographers. Even many novice amateurs can see these Canon lenses. The prices for such a device vary within 3000 rubles.

The optical system described has replaced the first version of the "half-ruble" of the CanonEF system. These devices differ only in their design, their optics are completely identical. The body of the lens is made of plastic, even the fastener of the bayonet is made of plastic. For comparison, the first version was produced in a metal case.

The second lens in question for Canon is EF50 mm ƒ / 1.4USM. It is considered average in the line of "fifties" of Canon. This model is much better than the previous lens. The case of the device is made of stronger and qualitative plastic, pleasant to the touch, mount bayonet - metal. However, this lens for Canon has a significant drawback - a rather flimsy plastic "proboscis", which is advanced when focusing. Very often, due to problems with this element, the lens is in the service center.

The third proposed device is the Canon 50mm EF ƒ / 1.2L USM lens. The case of the device is made of very high-quality plastic, mount bayonet - metal. The lens has small overall dimensions, but the mass of the device is 550 grams. The housing of the Canon 50 mm EF ƒ / 1.2L USM is waterproof and dustproof. It eliminated the drawback of the first models, namely, there are no retractable elements. When the lens is focused, the front lens goes into the body.

This concludes the 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 an equal footing with all world leaders in the production of photographic equipment.
