Pentax Optio 555 Digital Camera Camera


Though it isn't the most attractive point-and-shoot digital camera, the Optio 555 has nearly every feature you might ask for in one. This midsize, 5-megapixel model has aperture-priority, shutter-priority, and manual modes, plus several scene modes....

However, the Optio 555 is a little slow in a couple areas. The lens's length may contribute to a zoom that feels lethargic. The camera must extend the lens fully on start-up, and it does so slowly. We also noticed that the camera had a little trouble...

Pentax Optio 555


The Optio 555's body is crafted from aluminum alloy which makes it both light in weight and highly durable. The ultra-compact zoom system allows the lens to fully retract in two stages and helps reduce the depth of the camera. A single dial offers...

The Optio 555 excels at image recording quality with 5.0 effective megapixels and produces high quality, artistic images. Despite its compact size, the Optio 555 feature a high performance 5X optical zoom lens with 4X digital for an impressive 20X...

Digital Cameras - Pentax Optio 555 Camera Review, Information, Specifications

I liked the Optio 550 quite a bit -- is the 555 just as good? Find out now in our review

5X zoom in a compact body ; Very good photo quality ; Impressive battery life for a compact camera ; Full manual controls ; Live histogram in record mode ; Super macro mode allows you to get as close as 2 cm to subject ; Cool digital color filter...

Images slightly noisy, some vignetting ; Redeye ; Cheap plastic door over battery/memory card compartments ; Skimpy 16MB SD card included ; Average performance

While I don't think that Optio 550 owners should be racing out to upgrade, I do think that the Pentax Optio 555 is an attractive option for those who want a little more zoom in a compact camera. Not only will you get more zoom -- 5X in this case --...

Product Specifications

A successor to the popular Optio550, the Optio555 offers exceptionally compact and lightweight design that is ideal for use anywhere. PENTAX maximized the responsiveness of the Optio555 including reduced lag time so the camera is instantly ready when the power is turned on. In addition, a single touch of the playback button brings up recorded images and just a touch of the shutter button is all that is required to return to shooting. With enhanced operation capability and maximized responsiveness, the Optio555 allows satisfying shots to be taken with extreme ease. Add a powerful 5X optical zoom (4X digital zoom for a combined 20X total zoom), and the superb clarity of 5.0 effective megapixels, the Optio555 offers extreme versatility with superb detail and accuracy. The Optio555 also features PictBridge compatibility that eliminates the need for PC connectivity during printing by allowing the camera to be connected directly to a compatible printer. This feature allows direct control over printing and a full range of other functions.
