I want to buy a digital camera. There are two models to compare ~

Buying a camera is not as good as buying a Canon. Sony's things look good, but the quality is not necessarily the same. Buying Sony is mainly about buying its brand. Buying Canon is the right choice, and I also use Canon. This is what I can do for you. I did my best. I hope it works for you.

Canon S3 IS is an anti-shake telephoto digital camera with 6 million pixels and 12 times optical zoom performance. IS optical anti-shake function ensures that the photos are clear and unambiguous when holding a digital camera to the maximum extent, and USM motor has a very fast zoom speed, which is suitable for snapshot. Although the new S5 has been listed, S3 is favored by many consumers because of its good performance, good reputation and relatively low price.

Canon S3 is

Canon S3 IS is equipped with 12 times optical zoom lens, and its focal length is equivalent to 36-432mm of traditional 35mm camera. Extraordinary focal length range can meet the needs of various shooting subjects. When using telephoto, the blur caused by hand-held shooting will seriously affect the image quality. Canon's IS optical stabilization system can effectively improve this phenomenon. The application of USM ultrasonic motor ensures fast and quiet zoom when shooting, and the zoom process from the wide-angle end of the lens to the telephoto end takes only one second. In addition to the excellent performance of telephoto end, S3 also has super macro function. The nearest shooting distance is zero centimeters, which means that the lens can touch the subject.

Canon S3 is

Canon S3 IS uses a 6-megapixel CCD of 1/2.5 inches, with a maximum resolution of 28 16×2 1 12. Canon lens with optical zoom of 12 times is adopted, the focal length is equivalent to 36-432mm of the traditional 35mm camera, and the maximum aperture is F2.7-F3.5. ISO is 80/ 100/200/400/800. The shutter is 15- 1/3200 seconds, with a 2.0-inch LCD screen, 1 1.5 million pixels and an electronic viewfinder (EVF). Use SD card with 16MB. The battery system uses 4 No.5 AA batteries. The body weight of Canon S3 IS is about 4 10g, and the external dimensions are:113.4× 78× 75.5mm. Canon S3 IS has exposure modes such as automatic program exposure, aperture priority, shutter priority and full manual operation, and has the functions of manually adjusting ISO sensitivity and customizing white balance.

Canon's latest 12 x optical zoom digital camera S3 IS has been deeply loved by consumers since its launch. The price of this telephoto camera when it went on the market was 3800 yuan. Today, the author saw that the price of S3 IS in the market has been slightly lowered, and the latest price is 3750 yuan.
