Pentax Optio S4

 

Tiny and exceptionally easy to use, sharp pictures overall with especially good flash shots.

Slow to boot and recycle between shots, daylight shots can be underexposed.

Pentax Optio S4i Digital Camera

 

The Pentax Optio S4i's attractive silver metal body measures 3.3 by 2 by 0.8 inches, and the camera weighs only 4.5 ounces, including its rechargeable lithium ion battery. Somehow Pentax has managed to find room on the back of this tiny camera to fit a...

Pentax Optio S4i

 

Ultrasmall camera turns in unimpressive image quality.

The Pentax Optio S4i is relatively inexpensive and exceptionally easy to tote around, but its image quality falls short.

Review of the Pentax Optio S4i

 

Review of Pentax's new four megapixel ultracompact digital camera, the Optio S4i, which is the updated version the Optio S4 (just with a bigger LCD screen, better image quality, and a docking station), which was itself the follow-up to the...

Pentax Optio S4i

 

Extremely compact. Large LCD. Quick boot time and good battery life. Good feature set.

Nonstandard battery (which is hard to eject) and long recharge time. Flimsy and unwieldy plastic plugs. Small control buttons.

Pentax Optio S4

 

Stylish and ultracompact; nice selection of features for beginning and intermediate users.

Sluggish performance; finicky autofocus; below-average image quality.

Few competitors can top the S4's style and features, but many deliver better pictures and performance.

Pentax Optio S4

 

The Optio S4 features a patented sliding lens zoom mechanism that allows the camera's 3X (35-105mm in 35mm equivalent) optical lens to fully recede into the camera housing, flush with the body frame. This novel system helps protect the lens and helps...

Digital Cameras - Pentax Optio S4I Digital Camera Review, Information, Specifications

 

When I reviewed the Optio S4 (the predecessor to the S4i) last year, I was very impressed by it. I liked its compact design, rugged case, good image quality, and excellent feature set. While it's the same camera in many ways though, I didn't find...

The Optio S4i has a 3x zoom, 5.8-17.4mm lens, the equivalent of a 35-105mm lens on a 35mm camera, just like its predecessor, the Optio S4. The lens is where Pentax made a real innovation with the Optio S-series, in that its internal elements actually...
