Presenting the Pentax Optio S4

For some time now, we have been witnessing the decrease in size of ultra-compact cameras within the digital realm. With the arrival of the Pentax Optio S, and now the Pentax Optio S4, the meaning of the word “ultra-compact” has been totally redefined. The whole camera is so puny, it manages to fit neatly inside an empty Altoids© tin can (similar in size to a Strepsils tin can), making for an inexpensive hard camera case if you fancy that idea. Though small on size, it is certainly not meager in features as you will find out in this review.

Before we move on to the various aspects of the camera, here are the Pentax Optio S4’s detailed camera specifications:-
