In a (http://www.samsungsem.com/global/news/news/news/1510559_4630.jsp) press release , SEM explained that
optical zoom is achieved by adjusting the distance, or focal length, between an image sensor and the corresponding lens.
As for the 10X zoom technology by Oppo, it's expected to work in a manner similar to the 5X
optical zoom that the company showcased at MWC two years ago.
The new range of travel zoom cameras comes with further enhanced
optical zoom and image quality.
The Digital IXUS 110 IS offers the ultimate in wide shooting via a wide-angle zoom lens, wide-aspect LCD and widescreen HD movie shooting, while the Digital IXUS 990 IS delivers superior telephoto reach via a 5.0x
optical zoom, and detailed image review with a 3.0" PureColor LCD II.
Available in high-resolution color with 22X
optical zoom or day/night high-resolution color with 23X
optical zoom, the cameras can be viewed and controlled via the Internet using a standard Web browser.
The projector's 1.7x
optical zoom lens can display an 100-inch image on a screen from 9.8 feet away, and its 2:3 pull-down circuitry converts interlaced 480 and 575 video to progressive-scan imagery.
Boasting a swiveling lens like the ones in the popular Nikon Coolpix series, the SL300R has an image-processing chip dubbed "Rtune," which allows for up to 3.5 images to be recorded per second, a 3,170,000-pixel CCD knocking out images at a maximum resolution of 2,048 x 1,536 dots and video at a maximum of 640 x 480 dots, running at a not-too-jerky 15 frames per second; it also sports a 3x
optical zoom. That's a lot of gadgety stuff in a very tiny package.
* Oppo F19, Oppo F19 Pro may have 10x Hybrid
Optical ZoomThe rear camera consists of a large circular camera opening that bulges out and acts as the
optical zoom, and a huge flash.
"Both have a F2.4 aperture lens which delivers better low light photos, a 5x
optical zoom, and a 2.7-inch LCD display.
