Features & Controls

The Optio S1 comes packed with a 5x optical zoom lens that has a 35mm equivalent zoom range of 28-140mm (F3.9-5.7 maximum aperture range). This Pentax zoom lens is made up of 9 elements in 8 groups. When powered off the lens will retract into the body of the camera for protection. This unit does not accept filters.

Focus Range:
Normal: 1.31' to infinity (wide), 3.3' to infinity (tele)
Macro: 0.33 - 1.64' (wide), 0.98 - 1.64' (mid-zoom)
Super Macro: Approx 0.16 - 0.98' (wide)


Shown here is the built-in series-control auto flash on the Optio S1. Flash modes include: Auto, Flash Off, Flash On, Auto + Redeye, On + Redeye. It has a maximum effective range of up to 12' (W), 8.2' (T); at auto ISO.


The top of the S1 has only two controls. The power On/Off button is the smaller one on the left, along side the shutter release button.


The Optio S1 is sent out with a 2.7-inch TFT color LCD, with 230K dots. The display offers various brightness adjustments, as well as an anti-reflective coating to help reduce glare.


Controls on the back: At the very top are the zoom controls, also used for accessing the index and zoom controls while in playback mode. These are followed by the blue Playback button and the red movie record button. Moving down you will see the 4-way pad, with an OK button in the center, used navigate menus and select images during playback. This 4-way pad is also used as a shortcut to frequently used settings in record mode. Pressing 'Up' will enable self-timer mode, 'Left' to change flash mode, 'Right' to change focus mode, and 'Down' to change recording Mode. The MENU button calls up and dismisses the menus. The GREEN button quickly puts the camera into the 'Green' or simple (point-n-shoot) mode, and during in playback it functions as the Delete button.


On the right side of the Optio S1 you will find the PC/AV port, which handles both the USB 2.0 (High-speed) connection for downloading images and movies to your PC, and the Audio/Video output for TV display. There is no HDMI port.

The S1 can save photos and video to 42.7MB of on-board internal memory. However, that won't get you far when using the best image and video quality settings. Therefore, the camera also accepts SD, SDHC, and SDXC memory cards. We show a SanDisk Extreme SDHC memory card with 4GB of memory above.

The RS 1500 is powered by a Pentax 3.7V 720mAh Li-Ion rechargeable battery, with enough power to capture up to 210 images, or approximately 260mins of record time on a single charge. The battery is charged in-camera using the included USB cord. You can charge the camera from your PC (slower), or with the included AC adapter (fastest). While the ability to top off the battery with any available powered USB port sounds nice, that means you have to carry around the cable with you. Also, this makes charging one pack while using another virtually impossible.
