Canon Powershot A570IS Review.

Image Stabilization is the most important aspect in any camera which we are going to use . Let me first tell you all about Image stabilization .
*****************************************************************
Image stabilization (IS) is a family of techniques to increase the stability of an image. It is used in image-stabilized binoculars, photography, videography, and astronomical telescopes. With still cameras, camera shake is particularly problematic at slow shutter speeds or with long focal length (telephoto) lenses. With video cameras, camera shake causes visible frame-to-frame jitter in the recorded video. In astronomy, the problems of lens-shake are compounded by variations in the atmosphere over time, which cause the apparent position of objects to move.

In short i must say that image stabilization is techniques in which if your camera is moving or image is moving then you don't have to worry about the image , the image will be perfect .
Ok Now to the topic . Back to Review.

Build of The Camera

A little bulky but elegant is what I would label the A570IS as. Though the design standards stay similar in the whole of Canon's A500 series of digicams, the A570IS looks the classiest of the bunch. This would probably be because of the metallic parts that make an appearance in the otherwise plastic body, and the use of dark shades of gray for the text and the handgrip.

The build quality, overall, is quite sturdy and built to last. The buttons feel firm yet responsive, which is the way it should be.
The top of the A570 consists of the power and shutter release buttons, along with a mode dial. The shutter release button has a ring toggle switch for zooming in and out. I personally find that a lot more convenient than having a switch at the back of the camera for zooming. The mode dial allows you to select between basic shooting modes like portrait, landscape, etc. along with a scene mode where you can select something more specific. You also have a range of manual modes like, well, Manual, Shutter Priority, Aperture Priority, etc. Even the video shooting mode can be accessed via this dial.

The back of the camera contains the rest of the controls, along with a 2.5 inch LCD display that works pretty well under most lighting conditions. Even when shooting in bright sunlight, the image on the display was clearly visible. The part I really appreciate about this series of cameras is that they come with an optical viewfinder option. It may seem redundant when you have such a nice LCD display, but when you're trying to save the little juice you have in your batteries, shutting down the LCD can really help.

This is like most of the cameras contains i.e. Digital Cameras contains.

Features :
High Image Quality
•7.1 megapixel CCD for high-resolution images.
•Retractable 4x optical zoom with 4x digital zoom.
•High ISO 1600 reduces camera shake and blurring of fast-moving subjects even in low-light condition.
•Night Display function automatically brightens the subject on LCD to improve visibility.
•Powered by Canon proprietary DIGIC III Imaging Processor for high-definition images with natural colour reproduction and razor sharp clarity at accelerated processing speed, even under high ISO shooting.
•Optical Zoom Viewfinder saves battery life and focus better in dark condition and bright sunlight.

Face Detection Technology
• Incorporates the Face Detection AF, Face Detection AE and Face Detection FE, which work hand-in-hand to capture stunning photos of subjects’ faces with sharpness and right exposure easily.

Face Detection AF: Detects as many as 9 subjects’ faces in a picture. If no faces are detected the AF system automatically switched to the conventional 9-point AiAF setting.

Face Detection AE: Focus and exposure are controlled and set correctly for capturing the human face so that the subject’s best expression is not missed.

Face Detection FE: Flash brightness and exposure automatically adjusted to ideal levels

Enables Red eye correction during playback

NEW ISO 1600
•Makes sure fast moving subjects stay sharp and camera shake eliminated
•Avoid blurry subjects when shooting in dark areas

Point & Shoot Simplicity
•9-point AiAF (auto-focusing) or single point AF (fixed to center) ensures the subject is sharply focused even if it is not in the center.
•10 shooting modes including 10 special scene modes. The Special Scene modes are pre programmed camera settings for specific shooting conditions: Fireworks, Snow, Beach, Indoor, Kids & Pets, Night Snapshot, Foliage, Underwater, Aquarium, Night Scene

Sepia
Black & White

Shooting Preferences
•Shooting Instants increases shutter speed to a maximum of 1/2000th of a second
•Shooting in 3 dimensions focus on what is in front of the camera, or for a sharp focus overall effect
•Powerful zoom for users to zoom in even more closely to subjects without having to use a tele-converter attachment, thanks to the Digital Tele-converter function.
•Steady Shots with Optical Image Stabilizer (OIS) to ensure sharp and clear images when shooting without a tripod.

Image Playback Modes
•With Auto Rotate function, images will be displayed and oriented correctly during playback, regardless when taken with camera held vertically or horizontally.
•Resume Playback safely turn off the power or remove memory card and still resume playback from where the last viewed image was left off.
•Easy location and management of images through enhanced Jump function with jump searches:
Jump 10 images: Shows every tenth image
Jump 100 images: Shows every hundredth image
Jump shot date: Shows image taken at shooting date.
Jump to movie: Displays movie only.
Jump to folder: Goes to folder where image is stored.

Connectivity
•High speed USB 2.0 transfer rate
•Direct connectivity and transfer to both Windows (Windows 98 SE and above) & Mac (Mac OS X v10.1.5 and above) computers.

Shoot and Print/Transfer Direct

Sample Images By This camera



Beware that the Original image is a large one , before opening the original image Note down these Image Specifications:
* File Size: 4638 KB
* Recording Pixels: 3648 x 2736
* Compression: Superfine
* Shooting Mode: Av
* Shutter Speed: 1/40 sec.
* Aperture Value: f/5.6
* ISO Speed: 80
* Exp. Compensation: +2/3
* White Balance: Manual

Final Words :
All the speeds were pretty much top notch. The camera shot at around 1.7 FPS in burst mode, which is fast by any consumer model standards. The start-up to shot and shot-to-shot times were also minimal just the way its meant to be.
Canon has tried to cheat its way in the night portrait mode. To avoid image blurring when shooting without flash, it spikes up the ISO sensitivity levels, which results in high amounts of digital noise. But there's always an option of shooting in manual mode using a lower ISO level and higher exposure settings to get the perfect low-light shot like the one below.
he battery life was pretty good too. A pair of alkaline batteries can last for around 50 shots, some with flash and some without.
Conclusion
Anyway you look at it, the A570 is an excellent camera. It fills all the missing gaps in the lesser models to make a very strong mid-range camera. Though I personally think that the MRP of Rs. 16,990 is kind of an overkill, I think at the street price of Rs. 15,300 it's well worth it. Perfect for home usage as well as a user who wants to learn more about taking better pictures without shelling big bucks.
