Pentax Optio S55 Digital Camera Review


In the compact Optio S55, Pentax has included a 1/2.5-inch 5.36 total megapixel CCD and 3x optical zoom lens, equivalent to 35.6 - 107mm in 35mm format. Available online for as low as $212 (USD), the Optio S55 offers point-and-shoot consumers an...

-Good fit and finish -Simple styling -Very simple options for automatic settings -Large LCD screen

-Ridiculously short battery life -AA batteries, rather than dedicated rechargeable pack -No manual mode (except for white balance) -LCD in live view looks like an old T.V. with bad reception -Short zoom range -The camera does not have a "Sports"...

Many fundamental aspects of the Optio S55 - its size, 5 megapixel CCD, 3x optical zoom lens, 115,000-pixel LCD, $250-or-so street price - are decidedly middle-of-the-road. There are loads of cameras with those specs, because many, many snapshooters...

Pentax Optio S55


Although I have the Optio 555 this is the closest to match. The movie feature uses Quick Time only and only records in 1/15 fps. thats a real bummer. cheaper cameras do much better.

User friendly controls

Movies record at 1/15 fps which produces grainy finish. also a little on the heavy side although that helps keep the camera stable

Owners Opinion: Pentax Optio S55 (wandi guidolin, 17 Apr 06)


I bought a Pentax s55 without thinking too much. This camera is easy to use. Images are in average comparable to other cameras on this segment of cost. But....

I did not imagine that this camera eats batteries with an extraordinary speed. Unbelievable! So you must pay attention. Buy (if you like it) at least 5 couples of rechargeable batteries if you want to make at least 300 snapshots. Good luck ; Pentax in...

Be very careful when purchasing this camera. I bought mine from and it lasted about 3 weeks, before the LCD display (that's also the view finder) just stopped working. When contacting PENTAX tech support, their first questions was: has...

Owners Opinion: Pentax Optio S55 (Cynicalcec, 21 Aug 05)


As a " mature" novice I am currently trying several digicams. The Pentax has 3 POF's before software(1) eats batteries due to large LCD; (2) double flash (which is not advertised) and, "buttons are easily inadventently hit when handling.

3 above and the lack of a viewfinder turned me off. The software description was enough to dissuade me from loading it

Owners Opinion: Pentax Optio S55 (hrioo, 29 Jul 05)


After doing a lot of research I bought this camera. I must say that this is an excellent liitle digicam. It's not as small as some of the ultracompact models around but it easily fits in my jean's pockets and is easy to carry around. The image quality...

Flash recycle time is too slow. sometimes as long as 8 seconds ; Camera is basically non functional while flash is recycling ; Usb cable is not easy to fit to camera, it fits very tight

Pentax Optio S55


Pentax is a name that many people consider synonymous with photography, thus we would have expected it to do a little more with the Optio S55. It's no...

Reasonable image quality

Bulky, mediocre feature set

This is a very ordinary camera with very little to make it worth recommending. Look elsewhere.

Pentax Optio S55


Will Pentax ever run out of compact digital cameras? Cliff Smith seems to doubt it.

The control layout is simple enough, but this is not a simple camera, and I would certainly not recommend it for a first time user. My parents, both in their 70s, took the S55 on holiday to Italy to get me some good test shots. My father is a keen...
