The new Optio 550 and the Optio 450 from PENTAX - Distinctive clarity, distinguished digital performance
PENTAX Corporation is proud to present the Optio 550 and the Optio 450. Two cameras that follow in the footsteps of the popular Optio430 and Optio330, they offer high-level performance and are convenient enough to make you want to carry them everywhere. Each of the two new models has a compact body and a stylish design, yet provides high-quality images that satisfy. Even functionality and operability have been enhanced, and digital clarity is assured with the power of 5.0 and 4.0 effective megapixels respectively.
1. Sleek, sophisticated design
Stylishly crafted from aluminum alloy, and complete with a design accent that enhances the bases of the lenses, the Optio 550 and the Optio 450 convey a strong sense of refinement at the first glance. They also feel exceptionally comfortable in the hand and offer simple operation. As a result, the pleasure of these cameras comes as much from ownership as it does from usage. What's more, the dimensions of both cameras has also been reduced without a compromise in performance through use of an ultra-compact zoom lens that retracts in not one, but two stages when the power is switched off.
2. 5X optical zooming with an ultra-compact lens
Though the lenses on the Optio 550 and the Optio 450 are exceptionally compact, they succeed in offering a surprisingly high level of performance with 5X optical zooming. They deliver the satisfaction of high resolution while minimizing levels of distortion, and zooming power can be augmented through combination with digital 4X zoom for a total of 20X zoom performance. Both models also feature a convenient zoom button, that allows easy operation for swift composition as you desire.
3. The digital precision of 5.0 and 4.0 effective megapixels
The Optio 550 and the Optio 450 both excel when it comes to sheer image recording quality. Indeed, with 5.0 and 4.0 effective megapixels respectively, and the advantage of high-performance image processing technology, they have the ability to produce images of a much more artistic nature.
4. Simple, swift operation
Employing a newly designed processing circuit, the Optio 550 and the Optio 450 are as simple to use as they are stylish. The playback of images is made so much more easy and they are also both ready to shoot whenever the power is on. In fact, all you have to do to is compose your shot and press the shutter, so you can concentrate on content while the camera takes care of the technical details. The selection of shooting modes has also been made simple with single dial operation. This allows you to choose from Metered Manual, Shutter-priority AE, Aperture-priority AE, Program, Picture, Movie, Panorama Assist, 3D image, Digital Filter, User and Voice Recording modes with minimal effort. The Optio 550 and Optio 450 also offer standalone buttons for the easy access of frequently used shooting and playback functions, ways to customize the operational process, and handy functions such as quick deletion and quick enlargement.
5. 3D image mode achieves stereoscopic shooting
