The Powershot S70 is the "big brother" of the 5.0 megapixel PowerShot S60 and is aimed at the advanced user who wants full photographic control in a compact digital camera with very high resolution. The S70 combines a 7.1-megapixel imager with the same Canon 3.6x wide angle zoom lens used on the S60, it covers a 35mm equivalent of 28-100mm. This is a very high quality aspherical glass lens that produces image quality the equal of that found in the much larger professional cameras. And all of this state of the art imaging power is housed in a very compact, stylish and durable, two-toned dark metallic and black body.

Review

The S70's macro focus setting captures objects as close as 4 cm from the lens. The shutter speeds from 15 to 1/2000 second can be selected. When shooting photos in the RAW format, you can now select the resolution of the JPEG preview image that is simultaneously saved in the RAW image data. The Tv and Av modes have added the Safety Shift function, which automatically adjusts settings for an appropriate exposure when shooting.
