Canon PowerShot A75

In the market of digital photography concern Canon stands by its product range that covers all the needs of most amateur photographers: there are “reflex” – both for amateurs and professionals, scanners – the usual and slide printers for printing – inkjet and thermal diffusion, and Of course, there is one of the most extensive lines of amateur cameras.

Among them is a legendary models like the Canon PowerShot Pro 70 Canon Digital Ixus, and entry-level cameras, the so-called Series “A”, which is not actively marketed, but are no less popular.

The first camera in this series was introduced in 1998 Canon PowerShot A5. From the products of other manufacturers targeting the same market segment, the novelty is sleek and sturdy aluminum enclosure modest size and weight (103X68X33 mm and 320 g).

Autofocus lens (35mm equivalent 35mm camera) was a more-aperture (f / 2,5), than other models in the off state, he closed the lid does not move and is not removable cap, and automatic curtains, hidden in the body.

Resolution of the CCD was 1024X768, had an LCD display and flash, the data stored on the module CompactFlash. A year later came the model A5 Zoom, and A50, in the first major improvement was the camera lens (28-70 mm, f / 2,6-f / 4), the second – a new CCD with a resolution of 1280X960.

At first these cameras were formed family traits, inherited most of the camera series “A” – retractable into the housing autofocus zoom lens, covered by automatic shutters, the backlight and use AF for data storage modules CompactFlash.

After a year break, in 2001, Canon introduced a fairly compact (110X71X38 mm, 375 g) PowerShot A10 and A20, which were the progenitors of the family of cameras, producing to this day. This family, along with family features “A”-series, distinguished by the following characteristics:

plastic casing, as opposed to more typical for Canon using metal (aluminum or steel);

powered by four elements of “AA”, popularly called “penlight batteries” (previous models used a dedicated lithium-ion battery);

can be equipped with supplementary lenses and camera filters after removal of the decorative ring around the shaft of the lens and install tubusnogo adapter;

located directly above the lens pupil telescopic viewfinder, which reduces the effect of parallax;

unusual for a series of PowerShot ledge to keep on the right side.

removed from the emitter lens flare reduced the chance of “red eye” in the frame.

Cameras were equipped with relatively simple (compared to the same PowerShot G1) autofocus zoom lens (35-105 mm, f / 2,8-f / 4,8) and each matrix differed only resolution – 1280X960 1600X1200 from A10 and from A20. A set of photographic features initially was not rich – he allowed only exposure compensation and white balance adjustment. There was a continuous shooting mode at 2.5 frames per second.

AF illumination lamp has been integrated into the radiator of an outbreak. Forwarded data to the computer via USB. Distinguished feature of the camera – to power the internal clock and save the settings used by a tiny battery, which is used in watches and sometimes called “pill.”

A year later appeared PowerShot A30 and A40, which, in fact, are the same as A10 and A20, except for minor external changes – in particular, the decorative ring around the shaft of the lens was held at bayonet connector was removed and after clicking on the lock button under the lens. Inside, the changes were more pronounced – there was the video recording mode, the user was able to turn off the lights and autofocus mnogozonovy (three points) mode, set the different values ??of equivalent sensitivity (ISO 50, 100, 200 and 400), and switch to the matrix metering on the spot . Moreover, the cameras were rare for an entry-level camera to manual exposure settings. Model A40 in addition to resolution differed by the presence of a microphone on the front panel, which allows you to record video with a “sound track”.

In 2003, Canon released the PowerShot A30 and A40, the design of these models has changed markedly compared to predecessors. AF illumination lamp was no longer united with the flash and also help when you move the sharpness in the dark, was used to suppress the effect of “red eye”, as well as an indicator of the self-timer shooting.

The front panel of the two chambers had a microphone and a speaker appeared on the top, making it possible to not only view but also listen to the videos, was added to the opportunity to accompany images of voice commentary. Compartment for “pills”, which was previously combined with a compartment for modules CompactFlash, now located under the hood, concealed front-end connectors.

The controls are arranged in new ways – control zoom lens (which has remained the same) was carried out not by a few buttons on the rear panel, swivel lever, combined with the shutter button (in my opinion, it is more convenient). Mode switch was moved to the top panel, and for the translation of the camera shooting mode to playback mode and vice versa used by a separate switch, located on the rear panel.

The power button is also relocated to the upper panel, in general, has increased the number of buttons. To the right of the LCD display located there was a group of “cross” button, which provided as moving through the menu and control modes of the camera.

Internal changes were no less conspicuous – Resolution A60 was now 1600X1200, and the model A70 – 2048X1536. The number of AF areas was extended to five, in addition, there was a manual focus mode. Added a special program exposure modes, better known as “plots” – “Portrait” “Landscape”, “Night,” “shutter speed” and “long exposure”. There is also a priority shooting modes with the exposure and aperture priority. The user has the ability to set the white balance according to the standard (for example, a sheet of paper). Finally, each cell could give individuality – configuration section “My Camera” allows you to select the splash screen of the LCD and the sound that accompanied the inclusion of the camera, in addition, you can customize the sounds when you press the shutter button, pressing the other buttons, as well as to triggering the self-timer.

In the same year was presented chetyrehmegapikselny (2272X1704) option – PowerShot A80. The front exterior changes were not seen at all, but on the back they were very significant. First, change the location of the buttons and switch “shot show” was sliding, and not turning. Second, rather than arranged “cross” buttons appeared alone, but most who worked in the style of a mini-joystick – it can be pressed from all sides, “distorting” both up and down and side to side.

Third, the LCD was mounted on a hinge, which greatly simplifies photography from awkward positions, including a self-portrait shooting. In addition, the panel with a display screen can be deployed to the body and thus prevent it from accidental damage.

The left panel has been updated, too – the power connector moved to rear panel, in the same place were the USB interface and video output. The switch shooting modes on the top panel has two additional positions (“C1″ and “C2″), calls the two variants of pre-configured by the user of camera settings. Next to him was located LED lights up when the camera is turned on. Internal changes, except for authorization were to increase to nine the number of points mnogozonovogo autofocus functions and appearance of conservation.

And finally, in the spring of 2004 there was a camera which is the subject of this review – PowerShot A75. In fact, it was a model of the A70, which were used some good solutions, tested in A80.

Dimensions and mass of the plastic housing of the new cameras are the same as the previous models – 101X64X32 mm, 215 grams. Ledge on the right side of the camera allows photographers to confidently hold both small and large with the wrist.

Skin PowerShot A75 resembles both as A70, and A80, for example, the front panel of the camera coincides with the “seventieth” model. Rounded corners allow the camera to stick it in your pocket or small carrying case and, if necessary, to quickly retrieve and remove the scene of interest.

Autofocus zoom lens PowerShot A75 (35-105 mm equivalent 35mm camera, f/2.8-f/4.8) when you turn on the camera is pulled out of the body, and when switched off – hiding back in and closes automatically built-in shutters. Around the mine is located decorative ring of the lens, which can be removed by pressing the button located on the bottom. The ring hides the BNC connector, allowing you to install tubusny adapter, which, in turn, are mounted wide-angle lens and long-packed (and lens adapter sold separately).

Flash camera is at a sufficient distance from the lens, which reduces the chance of “red eye”. Beneath it is the autofocus illuminator, which is in low-light lights up orange, providing guidance on the focus. In addition, the self-timer, this lamp warns of shutter and the mode of suppression of the effect of “red eye” light bulb causes the constriction of the pupils photographed people and reduces the risk of “vampires” in the frame. The user can turn off the backlight auto-focus – for example, when photographing animals, which the light beam can be frightening.

The upper panel PowerShot A75 was similar with both A70, and with the A80 – a general layout of the controls was the same as “seventieth” model, but the outline of the dynamics resembled “eightieth.” Switch mode different from both predecessors and consisted of 13 items:

fully automatic – the user can adjust the resolution and compression level of personnel, switch between the flash and macro functions to include;

automatic exposure mode – in addition to the previous settings, you can use exposure compensation, adjust white balance, metering switch, choose a value equivalent to the sensitivity, as well as a choice between mnogozonovym (by nine points) and point autofocus;

the aperture priority mode – the user specifies the desired aperture value and shutter speed automatic counting chamber, in addition, you can still use all the above functions;

shutter priority mode on – similar to the previous mode, with the difference that the user specifies an excerpt;

manual exposure mode – the user specifies both the self-exposure parameters of the above functions, exposure compensation disappears and is replaced by the possibility of the correction pulse flash is not used preliminary, “measured” pulse, which allows the use of additional lights that are activated by light traps;

Scene Modes – “Portrait” “Landscape”, “Night,” “shutter speed”, “long exposure”;

mode “special stage”, under which lies the possibility of using the menu to select six subjects – “foliage”, “snow”, “beach”, “Fireworks,” “Underwater” and “Indoor”;

Video shooting mode – use the AVI format with resolutions 640X480, 320X240, or 160X120, frame rate 15 frames / sec and a “sound track” for the duration of the movie for half a minute and a maximum resolution of three minutes for the other two;

Panorama shooting mode that allows you to capture a series of overlapping vertical or horizontal frames, and then “glue” them on your computer into a single image.

To the left of the mode switch is a power button. Shutter button is put to the edge of the ledge to hold and is aligned with the rotatable lever that controls the zoom lens while shooting, and when viewing and includes an index scaled modes.
