Features of each of the firms (Canon)

Features of each of the firms “five” (the firm are in alphabetical order)

Canon

Current line EOS cameras from Canon is as follows (with increasing complexity): 5000, 500N (Rebel G), 1950 (ELAN II), 50E (ELAN IIE), (A2), 5 (A2E), 3 (in Blainville September 1998), 1N, 1N RS, are given in parentheses American names (the Canon some U.S. models have minor differences). Canon produces a great range of lenses and other accessories. Canon’s first with the development of cells began to build a motor for focusing, a lens (in 1987), resulting in no need of mechanical drive from the camera body. Moreover, it allowed a camera with a very fast autofocus system. Later, Nikon, too, began to produce such lenses (currently they only released a professional optics with motors). Canon with Minolta began to use multi-point AF. Also, it was designed Canon eye-control (control point of focus with pupil photographer), is used in the EOS 3 (45 points), EOS 5 and EOS 50E.

To control the outbreak of the firm Canon is using the most advanced mode E-TTL. Canon launches four lens with optical image stabilization (have an index IS), these lenses allow you to shoot without a “shake” when using fairly slow shutter speeds (up to 1 / 15 to 300 mm). Also produced lenses with optic axis tilt opportunity and prospects of the shift (the name of such lenses starts with TS-E), such lenses, for example, can get rid of perspective distortions when photographing architecture. Reflex produced at two factories in Japan, senior, junior in Taiwan.

Minolta

Line of cameras with AF as follows: a series of chambers called Dynax, in America Maxxum. Consists of the following models – 300si, 500si (Maxxum 400 si in America), 500si Super (in American, it appeared late and called the Maxxum 500si), 505si, 505si Super (Blainville in mid-1998), 600si, 700si (not performed ), 800si, Dynax 9 (replaced in autumn 1998 camera 9xi). Also available in models without AF – an X-300 and X-700. Minolta has released the first system of cameras with AF, occurred in 1986 (before that were only a few cameras with AF), and a long time multi-point autofocus system. Older Minolta SLR cameras are the regime “Eye Start”, ie dim when approaching the camera to the eye, they also have a special opportunity to read maps that are written additional software (in its latest camera 800si Minolta declined the opportunity). Very strong position in the production of devices Minolta metering (spot-, color-, flashmeter’ov). Optics Minolta is known for its quality. 9xi, 800si, 700si, 600si produced in Japan, 300si, which are sold in Moscow, usually made in China.

Nikon

Current line cameras with AF is as follows – F50 (N50), F601 (N6006), F60 (Blainville, in July 1998 to replace the F50), F70 (N70), F90X (N90S), F100 (Blainville, in November 1998) F5. After the release of F60 F50 and F601 release stopped, but they are still available. Also produced the camera without AF – FE10, FM10, FM2, F3. FE10/FM10 – inexpensive camera that produces a lot of evidence is not Nikon (the company itself Nikon on this issue does not give any comments). FM2 – an excellent purely mechanical camera (for example, has a shutter speed of 1 / 4000), more at one firm of such cameras in this price range there, purely mechanical Contax / Leica is worth significantly more expensive. F3 produced since 1980 and is considered a very convenient camera for studio shots, in which the AF is not needed. Also, Nikon SLR cameras produced for underwater filming and optics for large format cameras. In the Nikon camera was first used multispectral measurement.

Manufacturer Nikon has never changed the mechanics mount SLR cameras. In 1996 Blainville lenses with a motor inside for quick focusing (autumn 1998 presented similar zoom-obektvy 28-70/2.8 and 80-200/2.8). Nikon holds a special pricing / marketing policy, the emphasis shifted toward expensive models of shells and optics. There is a perception that Nikon cameras are more reliable. Ha our view, the moment it probably applies to its top-Series F3, F4, F5, but not more than, the level of technology in recent years has leveled off. “Senior” reflex produced in Japan, F50, F601 now, apparently, in Thailand (the Japanese versions are also sometimes found on sale), some lenses are manufactured in China.

Olympus

Releases SLR camera with built-in lens model IS-200 (replaced by the summer of 1997 IS-100), IS-3000 (IS-3). Also produces excellent SLR camera without autofocus OM-4Ti and OM-3Ti, these cameras have a variety of accessories for use with telescopes, medical equipment, etc. Olympus – optical group, the quality optics they are very high.

Pentax

Models with AF – MZ-1950 (ZX-50), MZ-1910 (ZX-10), MZ-5 (ZX-5), MZ-5n (ZX-5n), MZ-3 (available in Japan), Z1 -P (PZ1-P). Models without AF – is now out of production, expensive Pentax LX (camera in the class of Nikon F3, but less known for a number of reasons) and cheap Pentax K-1000, P-30T. Most recently was released Pentax MZ-M, neavtofokusnaya camera structurally close to the autofocus series MZ. The company also produces a Pentax medium format camera, including world’s first autofocus medium format SLR camera Pentax 645N.

From the standpoint of cost / opportunity is very good camera is PZ-1P. Unfortunately, the Pentax in Russia are not very well, the truth of the recent improvement in the situation and hope that this is a very worthy company will rightfully deserves her place on the market. Hekotorye cameras allow you to automatically change the focal length zoom-lenses. Pentax mount uses K, line native autofocus optics is not very large, but all you need to have very good quality. Using our optics AF cameras from Pentax, in some cases can lead to problems with electronic cameras. Plants from Pentax in different countries, including China / Vietnam.
